PART I



|Item 1. | Business
|------- | --------

Introduction

We develop, manufacture, market and sell innovative treatments for aortic disorders. Our
principal product, the Powerlink System is a minimally invasive device for the treatment of abdominal aortic aneurysm, or AAA. AAA is a weakening of the wall of the aorta, the largest artery of the body. Once AAA develops, it continues to enlarge
and if left untreated becomes increasingly susceptible to rupture. The overall patient mortality rate for ruptured AAAs is between 50% and 80%, making it a leading cause of death in the United States today.

The Powerlink System is a catheter and endoluminal stent graft, or ELG, system. The device consists of a self-expanding cobalt chromium
alloy stent cage covered by high density ePTFE. The Powerlink ELG is implanted in the abdominal aorta, which is accessed through the femoral artery. Once the Powerlink ELG is deployed into its proper position, blood flow is shunted away from the
weakened or aneurysmal section of the aorta, reducing pressure and the potential for the aorta to rupture. Our clinical trials demonstrated that implantation of our products reduces the mortality and morbidity rates associated with
conventional AAA surgery, as well as provides a clinical alternative for many patients who could not undergo conventional surgery. Sales of our Powerlink System in the United States, Europe, Asia, and South America are the sole source of our
reported revenue.

Industry Background

Atherosclerosis is the thickening and hardening of arteries. Some hardening of arteries occurs naturally as people grow older.
Atherosclerosis involves deposits of fatty substances, cholesterol, cellular waste products, calcium and other substances on the inner lining of an artery. Atherosclerosis is a slow, complex disease that starts in childhood and often progresses with
age.

Atherosclerosis also can reduce the integrity and strength of the blood vessel wall, causing the vessel to expand or
balloon out, which is known as an aneurysm. Aneurysms are commonly diagnosed in the aorta, which is the bodys largest artery. The highest incidence of aortic aneurysms occurs in the segment below the opening of the arteries that feed the
kidneys, the renal arteries, and the area where the aorta divides into the two iliac arteries that travel down the legs. Once diagnosed, patients with AAA require either a combination of medical therapy and non-invasive monitoring, or they must
undergo a procedure to repair the aneurysm.

For years, physicians have been interested in less invasive methods to treat AAA
disease as an alternative to open surgical repair. The high morbidity and mortality rates of this surgery are well documented, and medical pharmacological management for this condition carries the catastrophic risk of aneurysm rupture. Physicians
and commercial interests alike began investigating catheter-based alternatives to repair an aneurysm from within, utilizing surgical grafts in combination with stents to exclude blood flow and pressure from the weakened segment of the aorta.

We believe the appeal of the Powerlink System for patients, physicians, and health-care payors is compelling. The
conventional treatment is a highly invasive, open surgical procedure requiring a large incision in the patients abdomen, withdrawal of the patients intestines to provide access to the aneurysm, and the cross clamping of the aorta to stop
blood flow. This procedure typically lasts two to four hours and is performed under general anesthesia. The complication rates for the open surgical procedure, as well as ELG systems, vary depending upon patient risk classification.

An article published in the New England Journal of Medicine on January 31, 2008 compared the results of open surgical procedure and the
endovascular treatment of AAA on more than 45,000 patients over a three year period. Among the findings discussed in the article were:



| |  |  | The mortality rate of all patients in the study undergoing endovascular repair was approximately 1.2% as compared to 4.8% for open surgical repair.
Importantly, these findings are based on a patient population that typically has a significantly higher co-morbidity rate compared with those patients treated by open surgery.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Patients treated by endovascular repair were three times as likely to be discharged to their homes rather than another rehabilitation facility as
compared to patients treated with open repair. This results in substantial clinical and economic benefits for patients and payors alike.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The average hospital stay for patients in the study undergoing endovascular repair was 3.4 days versus 9.3 days for patients undergoing open repair.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | Open surgical repair entails risk of re-hospitalization due to problems associated with surgical incision. Patients had to be re-admitted over time for
surgical complications associated with the laparotomy, such as adhesions and bowel resections, at a much higher rate than those undergoing endovascular repair.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Market Opportunity

In the United States alone, it is estimated that between 1.2 million and 2 million people have an AAA. Although AAA is one of the most serious cardiovascular diseases, many AAAs are never
detected. Approximately 75% of AAA patients do not have symptoms at the time of their initial diagnosis, and AAAs generally are discovered inadvertently during procedures to diagnose unrelated medical conditions. Once an AAA develops, it continues
to enlarge and if left untreated, becomes increasingly susceptible to rupture. The overall patient mortality rate for ruptured aneurysms is between 50% and 80%.

We estimate that in 2009 over 200,000 people were diagnosed with AAA in the United States and that approximately 70,000 of those diagnosed underwent aneurysm repair, either via an ELG or via open surgery.

AAAs are generally more prevalent in people over the age of 65 and are more common in men than in women. In addition to the
current pool of potential patients, we expect that the number of persons seeking treatment for their condition will increase based on demographic factors. In 2009, the age 65 and over population in the United States numbered approximately
39 million, or 13% of the total population, and is expected to be 71 million by 2030. It is growing at a higher rate than the overall United States population.

Over the next several years, we forecast the United States ELG market to increase by at least 8% per year, and we estimate that up to 75% of AAA procedures will be performed using ELGs by 2013. We
estimate that the current total worldwide AAA market is approximately $965 million, with approximately $650 million of the market to be in the United States, and is expected to grow to approximately $1.3 billion by 2013. We expect that the total
aortic stent graft market (including thoracic stents, for which we do not currently have an approved product) will grow to $1.8 billion by 2013.

Our Strategy

Our objective is to become a leader in the development and
commercialization of innovative and cost effective products for the treatment of aortic disorders. Key elements of our strategy to accomplish this objective are as follows:



| |  |  | Focus exclusively on the aorta and become the industry expert in the treatment of aortic disorders;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | Provide innovative, less invasive devices for the treatment of aortic disorders with exceptional clinical results;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | Provide excellent clinical and technical support to physicians worldwide by building an experienced, knowledgeable and well-funded sales and marketing
organization.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our Products

Powerlink System

Our principal product is the Powerlink System for the treatment of AAA. The device consists of a self-expanding cobalt chromium alloy stent cage covered with high density ePTFE. The Powerlink ELG is
implanted in the abdominal aorta, gaining access through a small incision into the femoral artery. Once the Powerlink ELG is deployed into its proper position, blood flow is shunted away from the weakened, or aneurysmal, section of the aorta,
reducing pressure and the potential for the aorta to rupture.

We believe the Powerlink System is a superior design that
overcomes the inherent limitations of early generation AAA devices and offers the following advantages:



| |  |  | One-Piece, Bifurcated ELG. This eliminates many of the problems associated with early generation multi-piece systems. Our products eliminate
much of the guide wire manipulation required during the procedure to assemble the component parts of a modular system, thereby simplifying the procedure. In addition, in the follow-up period, there can be no limb component separation with a
one-piece system. We believe this should result in continued long-term exclusion of the aneurysm, and improved clinical results.

| |  |  | Anatomical Fixation. The Powerlink System is unique in that the placement of the stent graft on the aortoiliac bifurcation provides anatomical
fixation of the long main body device with the aortic extension providing seal at the infrarenal neck.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Fully Supported. The main body and limbs of the Powerlink System are fully supported by a cobalt chromium alloy stent. The cobalt chromium stent
greatly reduces or eliminates the risk of kinking of the stent graft in even tortuous anatomies, eliminating the need for additional procedures or costly peripheral stents. Kinking may result in reduced blood flow and limb thrombosis.

| |  |  | Unique, Minimally Invasive Delivery Mechanism. The Powerlink System requires only a small surgical incision in one leg. The other leg needs only
placement of a non-surgical introducer sheath, three millimeters in diameter. Other ELGs typically need surgical exposure of the femoral artery in both legs to introduce the multiple components. Our unique delivery mechanism and downsizing of the
catheter permits our technology to be used in patients having small or very tortuous access vessels.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Self-Expanding. The stent is formed from cobalt chromium alloy in a proprietary configuration that is protected by our patent portfolio. This
proprietary design expands to the proper size of the target aorta and eliminates the need for hooks or barbs for attachment. Based on our results to date, the Powerlink System has an excellent record of successful deployments.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Single Wire and Long Main Body Design. The long main body of the stent cage is made of a continuous wire which provides longitudinal support and
enables placement of the device on the aortic bifurcation, which minimizes the risk of migration.

Limitations of Earlier Technology

Our technology is dramatically different than other currently
available AAA devices. Despite enthusiasm by physicians and patients alike for minimally invasive technology, we believe early generation devices have achieved a limited market penetration due to design limitations and related complications. The
published clinical literature details many of the deficiencies of these approaches. In our opinion, early generation devices were limited because assembly was required by the surgeon. Multi-piece, or modular, systems require assembly by the mating
of multiple components to form a bifurcated stent graft within the aneurysm sac. These systems can be more difficult to implant and lead to longer operative times. In addition, there are a number of reports of component detachment during the
follow-up period. Component detachment can lead to a leak and a re-pressurization of the aneurysm sac. We believe this increases the risk of AAA rupture, often requiring a highly invasive, open surgical procedure to repair the detachment.

Powerlink System Products

Variations in patient anatomies require an adaptive technology. We designed our Powerlink System, with multiple proximal extensions, limb extensions, bifurcated main body lengths and diameters to simplify
procedures, improve clinical results, and drive product adoption by offering physicians a full line of products that are adaptable for treatment of the majority of patients with AAA disease.

Powerlink Infrarenal Bifurcated Systems. The Powerlink Infrarenal Bifurcated System is available in multiple diameters and lengths
and can treat patients that have an aortic neck up to 32 millimeters in diameter. The infrarenal device is made of a cobalt chromium alloy stent covered by high density ePTFE for placement below the renal arteries. The self-expanding stent permits
the graft to be used in a wide range of neck diameters, which allows us to treat a wide variety of anatomies with a standard device. We obtained the CE mark for this product in Europe in August 1999, U.S. Food and Drug Administration, or FDA,
pre-market approval, or PMA, in October 2004, and Shonin approval, which is equivalent to FDA approval of a PMA application in the United States, in Japan in February 2008. We commenced commercial sales in the United States in late 2004 and to Japan
in February 2008 through Cosmotec, our exclusive distributor in that country.

Powerlink Aortic Cuffs and Limb
Extensions. The Powerlink Proximal Extensions and Limb Extensions permit the physician to treat a greater number of patients. Proximal Extensions are available in 25, 28 and 34 millimeters in diameter and multiple lengths. They also are
available in both infrarenal and suprarenal configurations. Limb extensions are available in 16, 20, and 25 millimeters in diameter with various lengths, allowing the physician to customize the technology to treat a wide range of patient anatomies.
We have obtained the CE mark for these products in Europe in October 1999 (16/20 mm Limb Extensions), December 1999 (25/28 mm

Proximal Extensions), May 2002 (34 mm Proximal Extensions) and November 2008 (25 mm Limb Extensions). We obtained FDA marketing approval in October 2004 (25 and 28 mm proximal infrarenal
extensions and the 16 and 20 mm limb extensions), March 2008 (25 mm limb extensions), and October 2008 (34 mm proximal infrarenal and suprarenal extensions and 25 and 28 mm proximal suprarenal extensions). Our large diameter 34mm Proximal Extensions
are marketed under the trademark Powerlink XL.

IntuiTrak. In October 2008, we received FDA approval for a new system
to deliver and deploy the Powerlink System. The new system, called IntuiTrak, was designed to further simplify the implant procedure and provide a delivery profile advantage over many competitive devices. We had a full market introduction for the
product in the second quarter of 2009.

IntuiTrak Express.In March 2009, we received FDA approval for a new system to
deliver the Powerlink XL stent graft. This completes the application of IntuiTrak technology to the full range of sizes of the Powerlink System. IntuiTrak Express was introduced to the market at the Society for Vascular Surgery meeting in June 2009.

Clinical Trials

We continue to conduct clinical trials for other products related to the Powerlink System. In November 2009, we received an Investigational Device Exemption conditional approval from the FDA to begin a
prospective, multicenter, randomized clinical trial for a bilateral percutaneous approach to AAA repair. We plan to initiate this trial in the first quarter of 2010. The total cost of the trial is expected to be approximately $1.5 million, with the
majority of costs incurred in 2010. We expect to enroll 150 patients at 20 domestic clinical sites.

Research and
Development

We spent $6.6 million in 2009, $6.1 million in 2008, and $6.4 million in 2007, on research and
development, including clinical studies. Our focus is to continually develop innovative and cost effective medical device technology for the treatment of aortic disorders. We believe that our ability to develop new technologies is a key to our
future growth and success. Our research and development activities have focused, or are expected to focus, on technology that makes our existing products easier to use, developing products to treat patients with AAA that are not able to be treated
endovascularly due to limitations of currently marketed products and new technologies to address AAA and other aortic disorders, such as stent grafts for the thoracic region of the aorta. Historically, we have focused on developing the Powerlink
System for infrarental AAA, however, we believe that we will need to continue to devote more resources to new technologies for AAA and aortic disorders, such as juxtarenal and thoracic aneurysms, to continue to grow our business. Completing these
new product development activities will likely require significant cash resources and could take many years to complete, if at all.

Marketing and Sales

We sell and market products both in the United States and internationally. We sell
our products in the United States through a direct sales force and internationally through exclusive independent distributors. As of February 10, 2010, we marketed our products in 25 countries outside of the United States through 12 active
independent distributors.

United States. We market the Powerlink System in the United States through a direct sales
force consisting of just over 50 sales territories as of December 31, 2009 and we plan to add 30% more territories by the end of 2010. As of February 10, 2010, 50 of these territories were filled. The primary customer and decision maker for these
devices in the United States is the vascular surgeon. Through our direct sales force, we provide clinical support and service to many of the approximately 1,600 hospitals in the United States which perform endovascular aneurysm repair. We devote
significant resources to the training of our sales representatives, including educational programs on their interactions with physicians. Approximately 83% of our revenues for the year ended December 31, 2009 were generated from product sales in the
United States.

Europe. The market for ELGs in Europe is influenced by vascular surgeons, interventional radiologists
and, to a lesser extent, interventional cardiologists who perform catheter directed treatment of AAA. The European market is less concentrated than the U.S. market. We have obtained the right to affix a CE mark to our family of Powerlink System
products. Europe represents a smaller market opportunity due to capitated hospital budgets and a selling price that is typically less than in the United States. Approximately 6% of our revenues for the year ended December 31, 2009 were generated
from product sales in Europe. In addition, we have obtained regulatory approval but have not initiated the distribution process in several other countries, including Norway, Poland, Portugal, and Spain. We may or may not pursue these markets
depending on the availability of a suitable distribution partner.

Asia. We commenced commercial sales in Japan in
February 2008 after receipt of Shonin approval. We also commenced commercial sales in China in 2009 after receiving regulatory approval. Approximately 5% of our revenues for the year ended December 31, 2009 were generated from product sales in Asia.

South America and Mexico.We have obtained regulatory approval and have active
distribution partners in a number of countries, including Argentina, Brazil, Chile, Colombia, and Mexico. Approximately 6% of our revenues for the year ended December 31, 2009 were generated from product sales in South America.

Manufacturing and Supply

All of our products are manufactured, assembled, packaged and sterilized at our 30,200 square foot leased facility in Irvine, California. Our current manufacturing process is labor intensive and involves
shaping and forming a cobalt chromium stent, producing the high density ePTFE graft material to form the outside of the device, suturing the graft material on to the stent, and loading the device into a delivery catheter.

In April 2007, we received FDA approval to manufacture high density ePTFE graft material used for the Powerlink System. Beginning in 2008,
we manufactured all of our requirements for this graft material. Our cost to manufacture this graft material is significantly lower than our cost previously paid to a third party supplier of the graft material, which positively impacted our gross
margins for sales of the Powerlink System.

We rely on third parties for the supply of certain components used in our
products, such as wire used to form our cobalt chromium alloy stent cage. We outsource the manufacturing of these components as it allows us have relationships with suppliers who have appropriate competencies while minimizing our capital investment
and costs. Our third party manufacturers are required to meet FDA and/or ISO 13485 and other quality standards. We do not have long term supply arrangements with our suppliers. While we obtain some of these components from single source suppliers,
we believe there are alternative vendors for the supply of these components.

Patents and Proprietary Information

We believe that the protection of our intellectual property and proprietary information is a key to being able to
effectively compete. We are building a portfolio of apparatus and method patents covering various aspects of our current and future technology. In the AAA area, we have 18 United States patents issued, including 393 claims, and 21 pending United
States patent applications. Our current AAA related patents begin expiring in 2017 and the last patent expires in 2019. We intend to continue to file for patent protection to strengthen our intellectual property position as we continue to develop
our technology.

In addition to our AAA intellectual property, we own or have the rights to 36 issued United States patents,
one issued European patent, and one issued Japanese patent, and two pending United States patent applications relating to intravascular radiation, stents, and various catheter or intravascular technologies. The non-AAA patents begin expiring in 2012
and the last patent expires in 2018.

Our policy is to protect our proprietary position by, among other methods, filing United
States and foreign patent applications to protect technology, inventions and improvements that are important to the development of our business. We also own trademarks to protect the names of our products. In addition to patents and trademarks, we
rely on trade secrets and proprietary know-how. We seek protection of these trade secrets and proprietary know-how, in part, through confidentiality and proprietary information agreements. We make efforts to require our employees, directors,
consultants and advisors, other advisors and other individuals and entities to execute confidentiality agreements upon the start of employment, consulting or other contractual relationships with us. These agreements provide that all confidential
information developed or made known to the individual or entity during the course of the relationship is to be kept confidential and not be disclosed to third parties, except in specific circumstances. In the case of employees and some other
parties, the agreements provide that all inventions conceived by the individual will be our exclusive property.

Competition

The medical device industry is marked by intense competition. Any product we develop that
gains regulatory clearance or approval will have to compete for market acceptance and market share. We believe that the primary competitive factors in the market for AAA devices are:



| |  |  | clinical effectiveness;
| | - |  | -----------------------

| | - |  | ------

We
experience significant competition in the endovascular graft market and we expect that the intensity of competition will increase over time. Three manufacturers, Medtronic Inc., W.L. Gore Inc., and Cook Medical Products, Inc. have obtained FDA
marketing approval for their endovascular stent grafts. However, we believe that our technology offers clinical advantages over these other currently available technologies. The cardiovascular device industry is marked by rapid technological
improvements and, as a result, physicians are open to improved designs. Significant market share and revenue can be captured by designs demonstrating superior clinical outcomes. We believe deliverability of the device, dependability of the clinical
results and the durability of the product design are the most important product characteristics. The Powerlink System is the only available AAA device that provides anatomical fixation and gives physicians the choice of either infrarenal or
suprarenal proximal extensions.

The following chart details the stent graft characteristics of the minimally-invasive AAA
stent grafts being sold in the United States.

In addition to the
competitors mentioned above, Terumo-Vascutek, Trivascular, Nellix, Aptus, Cordis and Lombard Medical are believed to have active development programs.

Most of our existing competitors have substantially greater capital resources than we do and also have greater resources and expertise in the areas of research and development, obtaining regulatory
approvals, manufacturing, marketing, and sales. In addition, many of our competitors have multiple product offerings, which some physicians may find more convenient. We also compete with other medical device companies for clinical sites and for the
hiring of qualified personnel, including sales representatives.

Third-Party Reimbursement

In the United States, hospitals are the primary purchasers of our products. Hospitals then bill various third-party payors, such as Medicare,
Medicaid, and other government programs and private insurance plans, for the healthcare services and products provided to patients. Government agencies, private insurers and other payors determine whether to provide coverage for a particular
procedure and reimburse hospitals for medical treatment at a fixed rate based on the diagnosis-related group established by the United States Centers for Medicare and Medicaid Services, or CMS. The fixed rate of reimbursement is based on the
procedure performed, and is unrelated to the specific devices used in that procedure.

Reimbursement of interventional
procedures utilizing our products currently is covered under a diagnosis-related group. Some payors may deny reimbursement if they determine that the device used in a treatment was unnecessary, inappropriate or not

cost-effective, experimental or used for a non-approved indication. Therefore, we cannot assure you that reimbursement for any new product we develop will be available to hospitals and other
users, or that future reimbursement policies of payors will not hamper our ability to sell current or new products on a profitable basis.

In October 2000, the CMS issued a guideline regarding the proper coding of our procedures for billing purposes. CMS instructed that code 39.71, for endovascular graft repair of aneurysm, be utilized. For
purposes of hospital reimbursement, the majority of patients using the Powerlink System will be classified under DRG 237, Major Cardiovascular Procedures with Complication/ Co morbidity. In the latest data published by CMS, the national average
reimbursement for DRG 237, which includes hospital costs, approximated $27,250. In Europe, reimbursement for the procedure, including the device, typically comes from the hospitals general fund and is usually from about one-half to
three-quarters of the reimbursement available in the United States.

Outside the United States, market acceptance of products
depends partly upon the availability of reimbursement within the prevailing healthcare payment system. Reimbursement systems vary significantly by country, and by region within some countries, and reimbursement approvals must be obtained on a
country-by-country basis. Reimbursement is obtained from a variety of sources, including government sponsored healthcare and private health insurance plans.

Some countries have centrally organized healthcare systems, but in most cases there is a degree of regional autonomy either in deciding whether to pay for a particular procedure or in setting the
reimbursement level. The manner in which new devices enter the healthcare market depends on the system. There may be a national appraisal process leading to a new procedure or product coding, or it may be a local decision made by the relevant
hospital department. The latter is particularly the case where a global payment is made that does not detail specific technologies used in the treatment of a patient. Most foreign countries also have private insurance plans that may reimburse
patients for alternative therapies.

Government Regulation

United States

Our products are regulated in the United States as medical devices by the FDA under the Federal Food, Drug and Cosmetic Act. The FDA classifies medical devices into one of three classes based upon controls the FDA considers necessary to
reasonably ensure their safety and effectiveness. Class I devices are subject to general controls such as labeling, adherence to good manufacturing practices and maintenance of product complaint records, but are usually exempt from premarket
notification requirements. Class II devices are subject to the same general controls and also are subject to special controls such as performance standards, and FDA guidelines, and may also require clinical testing prior to approval. Class III
devices are subject to the highest level of controls because they are used in life-sustaining or life-supporting implantable devices. Class III devices require rigorous clinical testing prior to their approval and generally require a PMA or PMA
supplement approval prior to their sale.

If a medical device manufacturer can establish that a device is substantially
equivalent to a legally marketed Class I or Class II device, or to an unclassified device, or to a Class III device for which the FDA has not called for PMAs, the manufacturer may seek clearance from the FDA to market the device by filing a
510(k) premarket notification. The 510(k) notification must be supported by appropriate data establishing the claim of substantial equivalence to the satisfaction of the FDA. Following submission of the 510(k) notification, the manufacturer may not
place the device into commercial distribution in the United States until an order is issued by the FDA.

Manufacturers must
file an investigational device exemption (IDE) application if human clinical studies of a device are required and if the FDA considers experimental use of the device to represent significant risk to the patient. The IDE application must be supported
by data, typically including the results of animal and mechanical testing of the device. If the IDE application is approved by the FDA, human clinical studies may begin at a specific number of investigational sites with a maximum number of patients,
as approved by the FDA. The clinical studies must be conducted under the review of an independent institutional review board to ensure the protection of the patients rights.

Generally, upon completion of these human clinical studies, a manufacturer seeks approval of a Class III medical device from the FDA by
submitting a PMA application. A PMA application must be supported by extensive data, including the results of the clinical studies, as well as literature to establish the safety and effectiveness of the device. The Powerlink System was approved
through this PMA process.

FDA regulations require us to register as a medical device manufacturer with the FDA. Additionally,
the California Department of Health Services, or CDHS, requires us to register as a medical device manufacturer within the state. Because of this, the FDA and the CDHS inspect us on a routine basis for compliance with Quality System Records, or QSR,
regulations. These regulations require that we manufacture our products and maintain related documentation in a proscribed manner with respect to manufacturing, testing and control activities. We have undergone and expect to continue to undergo
regular QSR inspections in connection with the manufacture of our products at our facility. Further, the FDA requires us to comply with various FDA regulations regarding labeling. The Medical Device Reporting laws and regulations require us to
provide information to the FDA on deaths or serious injuries alleged to have been associated with the use of our devices, as well as product malfunctions that likely would cause or contribute to death or serious injury if the malfunction were to
recur. In addition, the FDA prohibits an approved device from being marketed for off-label purposes.

We are
subject to other federal, state and local laws, regulations and recommendations relating to safe working conditions, laboratory and manufacturing practices.

International

Our international sales are subject to regulatory requirements in the countries in which our products are sold. The regulatory review process
varies from country to country and may in some cases require the submission of clinical data. In addition, the FDA must approve the export to certain countries of devices that require a PMA but are not yet approved domestically.

In Europe, we need to comply with the requirements of the Medical Devices Directive, or MDD, and affix the CE mark on our products to attest
to such compliance. To achieve compliance, our products must meet the Essential Requirements of the MDD relating to safety and performance and we must successfully undergo verification of our regulatory compliance, or conformity
assessment, by a Notified Body selected by us. The level of scrutiny of such assessment depends on the regulatory class of the product.

In December 1998, we received ISO 9001:1994/ EN46001:1996 certification from our Notified Body with respect to the manufacturing of all of our products in our facilities. In September 2002, we received
ISO 9001:1994/ EN46001:1996 and ISO 13485:1996 certification. In December 2005, we received ISO13485:2003 certification. We are subject to continued surveillance by our Notified Body and will be required to report any serious adverse incidents to
the appropriate authorities. We also must comply with additional requirements of individual countries in which our products are marketed.

Fraud and Abuse

We may directly or indirectly be subject to various
federal and state laws pertaining to healthcare fraud and abuse, including anti-kickback laws. In particular, the federal healthcare program anti-kickback statute prohibits persons from knowingly and willfully soliciting, offering, receiving or
providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing, arranging for or recommending a good or service, for which payment may be made in whole or part under federal
healthcare programs, such as the Medicare and Medicaid programs. The anti-kickback statute is broad and prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. In implementing the statute, the
Office of Inspector General, or OIG, has issued a series of regulations, known as the safe harbors, which began in July 1991. These safe harbors set forth provisions that, if all their applicable requirements are met, will assure
healthcare providers and other parties that they will not be prosecuted under the anti-kickback statute. The failure of a transaction or arrangement to fit precisely within one or more safe harbors does not necessarily mean that it is illegal or
that prosecution will be pursued. However, conduct and business arrangements that do not fully satisfy all requirements of an applicable safe harbor may result in increased scrutiny by government enforcement authorities such as the OIG. Penalties
for violations of the federal anti-kickback statute include criminal penalties and civil sanctions such as fines, imprisonment and possible exclusion from Medicare, Medicaid and other federal healthcare programs.

The federal False Claims Act prohibits persons from knowingly filing or causing to be filed a false claim to, or the knowing use of false
statements to obtain payment from, the federal government. Suits filed under the False Claims Act, known as qui tam actions, can be brought by any individual on behalf of the government. These individuals, sometimes known as
relators or, more commonly, as whistleblowers, may share in any amounts paid by the entity to the government in fines or settlement. The number of filings of qui tam actions has increased significantly in recent years,
causing more healthcare companies to have to defend a False Claim action. If an entity is determined to have violated the federal False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus
civil penalties for each separate false claim. Various states have also enacted similar laws modeled after the federal False Claims Act which apply to items and services reimbursed under Medicaid and other state programs, or, in several states,
apply regardless of the payor.

The Health Insurance Portability and Accountability Act of 1996, or HIPAA, created two new
federal crimes: healthcare fraud and false statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private payors. A violation
of this statute is a felony and may result in fines, imprisonment or exclusion from government sponsored programs. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any
materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items, or services. A violation of this statute is a felony and may result in fines or imprisonment.

Product Liability

The manufacture and marketing of medical devices carries the risk of financial exposure to product liability claims. Our products are used in situations in which there is a high risk of serious injury or
death. Such risks will exist even with respect to those products that have received, or in the future may receive, regulatory approval for commercial sale. We are currently covered under a product liability insurance policy with coverage limits of
$10 million per occurrence and $10 million per year in the aggregate subject to usual self insured retention amounts.

Employees

As of December 31, 2009, we had 197 employees, including 91 in manufacturing, 13 in
research and development, nine in regulatory and clinical affairs, 70 in sales, marketing and customer service and 14 in administration. We believe that the success of our business will depend, in part, on our ability to attract and retain qualified
personnel. Our employees are not subject to a collective bargaining agreement, and we believe we have good relations with our employees.

|Item 1A. | Risk Factors
|-------- | ------------

The
following risks could affect our business, financial results and results of operations. These risk factors should be considered in connection with evaluating the forward-looking statements contained in this Annual Report on Form 10-K because these
factors could cause actual results and conditions to differ materially from those projected in the forward-looking statements.

All of our revenue is generated from the Powerlink System, and any declines in the sale of this product will negatively impact our business.

We have focused heavily on the development and commercialization of a single technology, the Powerlink System, because of limited resources. If we are unable to continue to achieve market acceptance of
the Powerlink System and do not achieve sustained positive cash flow from operations, we will be constrained in our ability to fund development and commercialization of improvements and other product lines. In addition, if we are unable to market
the Powerlink System as a result of failure to maintain regulatory approvals, we would lose our only source of revenue and business would be negatively affected.

Our success depends on the growth in the number of AAA patients treated with endovascular devices.

In the United States, over 200,000 new diagnoses of AAA are made each year. In 2009, approximately 70,000 AAA patients were treated by either endovascular repair or by open surgery. Our success with our
Powerlink System will depend on an increasing percentage of patients with AAA being diagnosed, and an increasing percentage of those diagnosed receiving endovascular, as opposed to open surgical procedures. Initiatives to increase screening for AAA
are underway but are out of our control and such general screening programs may never gain wide acceptance. The failure to diagnose more patients with AAA, could negatively impact sales of the Powerlink System.

Our success depends on convincing physicians to use the Powerlink System in more endovascular AAA procedures.

We believe that physicians may have chosen to use our Powerlink System for AAA procedures that involved abnormal vasculatures, such as those
with difficult neck anatomies, while using competitive products for more normal vasculatures. We believe physicians did not choose the Powerlink System for these more common endovascular AAA procedures primarily as result of the perception of the
ease of use of competitive products versus the Powerlink System. However, with the introduction of our IntuiTrak delivery system, we believe that physicians will be more willing to use the Powerlink System in a wider variety of endovascular AAA
procedures. However, if we are unable to convince physicians of the ease of use of the Powerlink System and IntuiTrak compared to competitive products, we may not be able to achieve our anticipated growth and our business could be negatively
impacted.

Our international operations subject us to certain operating risks, which could adversely impact our net
sales, results of operations and financial condition.

Sales of our products outside the United States represented
approximately 17% of our revenue in 2009. During 2009, we sold our products through twelve distributors located in the following countries outside of the United States: Argentina, Brazil, Chile, Colombia, Germany, Greece, Ireland, Italy, Japan,
Mexico, China, and Turkey. The sales territories authorized within these various distribution agreements cover a total of twenty five countries. The sale and shipment of our products across international borders, as well as the purchase of
components and products from international sources, subject us to extensive U.S. and foreign governmental trade, import and export, and custom regulations and laws. Compliance with these regulations is costly and exposes us to penalties for
non-compliance. Other laws and regulations that can significantly impact us include various anti-bribery laws, including the U.S. Foreign Corrupt Practices Act and anti-boycott laws. Any failure to comply with applicable legal and regulatory
obligations could impact us in a variety of ways that include, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of export privileges, seizure of
shipments, restrictions on certain business activities, and exclusion or debarment from government contracting. Also, the failure to comply with applicable legal and regulatory obligations could result in the disruption of our shipping and sales
activities.

| |  |  | the imposition of U.S. or international sanctions against a country, company, person or entity with whom we do business that would restrict or prohibit
continued business with the sanctioned country, company, person or entity;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | economic instability;
| | - |  | ---------------------



| |  |  | a shortage of high-quality sales people and distributors;
| | - |  | ---------------------------------------------------------



| |  |  | changes in third-party reimbursement policies that may require some of the patients who receive our products to directly absorb medical costs or that
may necessitate the reduction of the selling prices of our products;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in duties and tariffs, license obligations and other non-tariff barriers to trade;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | the imposition of new trade restrictions;
| | - |  | -----------------------------------------



| |  |  | the imposition of restrictions on the activities of foreign agents, representatives and distributors;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | scrutiny of foreign tax authorities which could result in significant fines, penalties and additional taxes being imposed on us;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | pricing pressure that we may experience internationally;
| | - |  | --------------------------------------------------------



| |  |  | laws and business practices favoring local companies;
| | - |  | -----------------------------------------------------



| |  |  | longer payment cycles;
| | - |  | ----------------------



| |  |  | difficulties in maintaining consistency with our internal guidelines;
| | - |  | ---------------------------------------------------------------------



| |  |  | difficulties in enforcing agreements and collecting receivables through certain foreign legal systems; and
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | difficulties in enforcing or defending intellectual property rights.
| | - |  | --------------------------------------------------------------------

If we experience any of these risks, our sales in international countries may be harmed and our results of operations would suffer.

If our products or processes infringe upon the intellectual property of third parties, the sale of our products may be
challenged and we may have to defend costly and time-consuming infringement claims.

We may need to engage in
expensive and prolonged litigation to assert or defend any of our intellectual property rights or to determine the scope and validity of rights claimed by other parties. With no certainty as to the outcome, litigation could be too expensive for us
to pursue. Our failure to prevail in such litigation or our failure to pursue litigation could result in the loss of our rights that could hurt our business substantially. In addition, the laws of some foreign countries do not protect our
intellectual property rights to the same extent as the laws of the United States, if at all.

##### Table of Contents

Our failure to obtain rights to intellectual property of third parties or the potential for
intellectual property litigation could force us to do one or more of the following:



| |  |  | stop selling, making or using products that use the disputed intellectual property;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | obtain a license from the intellectual property owner to continue selling, making, licensing or using products, which license may not be available on
reasonable terms, or at all;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign our products, processes or services; or
| | - |  | ------------------------------------------------



| |  |  | subject us to significant liabilities to third parties.
| | - |  | -------------------------------------------------------

If any of the foregoing occurs, we may be unable to manufacture and sell our products and may suffer severe financial harm. Whether or not
an intellectual property claim is valid, the cost of responding to it, in terms of legal fees and expenses and the diversion of management resources, could harm our business.

If third-party payors do not provide reimbursement for the use of the Powerlink System, our revenues may be negatively impacted.

Our success in marketing the Powerlink System depends in large part on whether domestic and international government
health administrative authorities, private health insurers and other organizations will reimburse customers for the cost of our product. Reimbursement systems in international markets vary significantly by country and by region within some
countries, and reimbursement approvals must be obtained on a country-by-country basis. Further, many international markets have government managed healthcare systems that control reimbursement for new devices and procedures. In most markets there
are private insurance systems as well as government-managed systems. If sufficient reimbursement is not made available for the Powerlink System, or any other product that we may develop, in either the United States or internationally, the demand for
our products will be adversely affected.

Current challenges in the commercial and credit environment may adversely
affect our business and financial condition.

The global financial markets have experienced unprecedented levels of
volatility. Our ability to generate cash flows from operations or enter into or maintain existing financing arrangements on acceptable terms could be adversely affected if there is a material decline in the demand for our products or in the solvency
of our customers, deterioration in our key financial ratios, maintenance of compliance with financial covenants in existing credit agreements, or credit ratings, or other significantly unfavorable changes in conditions. While these conditions and
the current economic downturn have not meaningfully impaired our ability to access credit markets or meaningfully adversely affected our operations to date, continuing volatility in the global financial markets could increase borrowing costs or
affect our ability to access the capital markets. Current or worsening economic conditions may also adversely affect the business of our customers, including their ability to pay for our products and services, and the amount spent on healthcare
generally. This could result in a decrease in the demand for our products and services, longer sales cycles, slower adoption of new technologies and increased price competition.

Our operating results may vary significantly from quarter to quarter, which may negatively impact our stock price in the future.

Our quarterly revenues and results of operations may fluctuate due to, among others, the following reasons:



| |  |  | physician acceptance of the Powerlink System;
| | - |  | ---------------------------------------------



| |  |  | the conduct and results of clinical trials;
| | - |  | -------------------------------------------



| |  |  | the timing and expense of obtaining future regulatory approvals;
| | - |  | ----------------------------------------------------------------



| |  |  | fluctuations in our expenses associated with expanding our operations;
| | - |  | ----------------------------------------------------------------------



| |  |  | the introduction of new products by our competitors;
| | - |  | ----------------------------------------------------



| |  |  | supplier, manufacturing or quality problems with our devices;
| | - |  | -------------------------------------------------------------



| |  |  | the timing of stocking orders from our distributors;
| | - |  | ----------------------------------------------------

##### Table of Contents

| |  |  | changes in our pricing policies or in the pricing policies of our competitors or suppliers; and
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | changes in third-party payors reimbursement policies.
| | - |  | ------------------------------------------------------

Because of these and possibly other factors, it is likely that in some future period our operating results will not meet investor
expectations or those of public market analysts.

Any unanticipated change in revenues or operating results is likely to cause
our stock price to fluctuate since such changes reflect new information available to investors and analysts. New information may cause investors and analysts to revalue our stock, which could cause a decline in the trading price of our stock.

We have limited resources to invest in research and development and to grow our business and may need to raise
additional funds in the future for these activities.

We believe that our growth will depend, in significant part, on
our ability to develop new technologies for the treatment of AAA and other aortic disorders and technology complementary to the Powerlink System. Our existing resources may not allow us to conduct all of the research and development activities that
we believe would be beneficial for our future growth. As a result, we may need to seek funds in the future to finance these activities. If we are unable to raise funds on favorable terms, or at all, we may not be able to increase our research and
development activities and the growth of our business may be negatively impacted.

Our future success depends on our
ability to develop, receive regulatory clearance or approval for, and introduce new products or product enhancements that will be accepted by the market in a timely manner.

It is important to our business that we continue to build a more complete product offering for treatment of AAA and other aortic disorders.
As such, our success will depend in part on our ability to develop and introduce new products and enhancements to the Powerlink System. However, we may not be able to successfully develop and obtain regulatory clearance or approval for product
enhancements, or new products or our future products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.

The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:



| |  |  | properly identify and anticipate physicians and patient needs;
| | - |  | --------------------------------------------------------------



| |  |  | develop and introduce new products or product enhancements in a timely manner;
| | - |  | ------------------------------------------------------------------------------



| |  |  | avoid infringing upon the intellectual property rights of third parties;
| | - |  | ------------------------------------------------------------------------



| |  |  | demonstrate, if required, the safety and efficacy of new products with data from preclinical studies and clinical trials;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | obtain the necessary regulatory clearances or approvals for new products or product enhancements;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | be fully FDA-compliant with marketing of new devices or modified products;
| | - |  | --------------------------------------------------------------------------



| |  |  | provide adequate training to potential users of our products;
| | - |  | -------------------------------------------------------------



| |  |  | receive adequate coverage and reimbursement for procedures performed with our products; and
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | develop an effective and FDA-compliant, dedicated marketing and distribution network.
| | - |  | -------------------------------------------------------------------------------------

If we do not develop new products or product enhancements in time to meet market demand or if there is insufficient demand for these
products or enhancements, our results of operations will suffer.

##### Table of Contents

If clinical trials of our current or future product candidates do not produce results
necessary to support regulatory clearance or approval in the United States or elsewhere, we will be unable to commercialize these products.

We are currently conducting clinical trials and will likely need to conduct additional clinical trials in the future in support of new product approvals or approval for new indications for use. Clinical
testing is expensive, typically takes many years and has an uncertain outcome. The initiation and completion of any of these studies may be prevented, delayed or halted for numerous reasons, including, but not limited to, the following:



| |  |  | the FDA, institutional review boards or other regulatory authorities do not approve a clinical study protocol, force us to modify a previously approved
protocol, or place a clinical study on hold;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | patients do not enroll in, or enroll at the expected rate, or complete a clinical study;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | patients or investigators do not comply with study protocols;
| | - |  | -------------------------------------------------------------



| |  |  | patients do not return for post-treatment follow-up at the expected rate;
| | - |  | -------------------------------------------------------------------------



| |  |  | patients experience serious or unexpected adverse side effects for a variety of reasons that may or may not be related to our products such as the
advanced stage of co-morbidities that may exist at the time of treatment, causing a clinical study to be put on hold;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | sites participating in an ongoing clinical study may withdraw, requiring us to engage new sites;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | difficulties or delays associated with bringing additional clinical sites on-line;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | third-party clinical investigators decline to participate in our clinical studies, do not perform the clinical studies on the anticipated schedule or
consistent with the investigator agreement, clinical study protocol, good clinical practices, and other FDA and Institutional Review Board requirements;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | third-party organizations do not perform data collection and analysis in a timely or accurate manner;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | regulatory inspections of our clinical studies require us to undertake corrective action or suspend or terminate our clinical studies;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in U.S. federal, state, or foreign governmental statutes, regulations or policies;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | interim results are inconclusive or unfavorable as to immediate and long-term safety or efficacy; or
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | the study design is inadequate to demonstrate safety and efficacy.
| | - |  | ------------------------------------------------------------------

Clinical failure can occur at any stage of the testing. Our clinical trials may produce negative or inconclusive results, and we may decide,
or regulators may require us, to conduct additional clinical and/or non-clinical testing in addition to those we have planned. Our failure to adequately demonstrate the efficacy and safety of any of our devices would prevent receipt of regulatory
clearance or approval and, ultimately, the commercialization of that device or indication for use.

If any future
acquisitions or business development efforts are unsuccessful, our business may be harmed.

As part of our business
strategy, we may acquire other companies, technologies and product lines to maintain our objectives of developing or acquiring innovative technologies. Acquisitions involve numerous risks, including the following:



| |  |  | the possibility that we will pay more than the value we derive from the acquisition, which could result in future non-cash impairment charges;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in integration of the operations, technologies, and products of the acquired companies, which may require significant attention of our
management that otherwise would be available for the ongoing development of our business;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the assumption of certain known and unknown liabilities of the acquired companies; and
| | - |  | --------------------------------------------------------------------------------------



| |  |  | difficulties in retaining key relationships with shareowners (employees), customers, partners and suppliers of the acquired company.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------

In addition, we may invest in new technologies that may not succeed in the marketplace. If they are not
successful, we may be unable to recover our initial investment, which could include the cost of acquiring the license, funding development efforts, acquiring products or purchasing inventory. Any of these would negatively impact our future growth
and cash reserves.

Our business is subject to extensive governmental regulation that could make it more expensive and
time consuming for us to introduce new or improved products.

Our products must comply with regulatory requirements
imposed by the FDA and similar agencies in foreign countries. These requirements involve lengthy and detailed laboratory and clinical testing procedures, sampling activities, an extensive FDA review process, and other costly and time-consuming
procedures. It often takes several years to satisfy these requirements, depending on the complexity and novelty of the product. We also are subject to numerous additional licensing and regulatory requirements relating to safe working conditions,
manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. Some of the most important requirements we face include:



| |  |  | FDA approval process;
| | - |  | ---------------------



14

##### Table of Contents

| |  |  | California Department of Health Services requirements;
| | - |  | ------------------------------------------------------



| |  |  | ISO 9001:1994 and ENISO 13485:2003; and
| | - |  | ---------------------------------------



| |  |  | European Union CE mark requirements.
| | - |  | ------------------------------------

Government regulation may impede our ability to conduct continuing clinical trials of Powerlink System enhancements and to manufacture the Powerlink System and other prospective products. Government
regulation also could delay our marketing of new products for a considerable period of time and impose costly procedures on our activities. The FDA and other regulatory agencies may not approve any of our future products on a timely basis, if at
all. Any delay in obtaining, or failure to obtain, such approvals could negatively impact our marketing of any proposed products and reduce our product revenues.

Our products remain subject to strict regulatory controls on manufacturing, marketing and use. We may be forced to modify or recall our product after release in response to regulatory action or
unanticipated difficulties encountered in general use. Any such action could have a material effect on the reputation of our products and on our business and financial position.

Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which
could harm our business. We could also be subject to new federal, state or local regulations that could affect our research and development programs and harm our business in unforeseen ways. If this happens, we may have to incur significant costs to
comply with such laws and regulations, which will harm our results of operations.

The use, misuse or off-label use of
our products may harm our image in the marketplace or result in injuries that lead to product liability suits, which could be costly to our business or result in FDA sanctions if we are deemed to have engaged in such promotion.

Our currently marketed products have been cleared by the FDA for specific treatments and anatomies. We cannot, however, prevent a
physician from using our products outside of those indications cleared for use, known as off-label use. There may be increased risk of injury if physicians attempt to use our products off-label. We train our sales force not to promote our products
for off-label uses. Furthermore, the use of our products for indications other than those indications for which our products have been cleared by the FDA may not effectively treat such conditions, which could harm our reputation in the marketplace
among physicians and patients. Physicians may also misuse our products or use improper techniques if they are not adequately trained, potentially leading to injury and an increased risk of product liability. If our products are misused or used with
improper technique, we may become subject to costly litigation by our customers or their patients. Product liability claims could divert managements attention from our core business, be expensive to defend and result in sizable damage awards
against us that may not be covered by insurance. If we are deemed by FDA to have engaged in the promotion of any our products for off-label use, we could be subject to FDA prohibitions on the sale or marketing of our products or significant fines
and penalties, and the imposition of these sanctions could also affect our reputation and position within the industry. Any of these events could harm our business and results of operations and cause our stock to decline.

If we fail to develop and grow our direct sales force, our business could suffer.

We have a nationally staffed direct sales force and we utilize a network of third-party distributors for sales outside of the United States.
As we launch new products and increase our marketing efforts with respect to existing products, we will need to retain and develop our direct sales personnel to build upon their experience, tenure with our products, and their business relationships.
There is significant competition for sales personnel experienced in relevant medical device sales. If we are unable to attract, motivate, develop, and retain qualified sales personnel and thereby grow our sales force, we may not be able to maintain
or increase our revenues.

##### Table of Contents

Our third-party distributors may not effectively distribute our products.

We depend on medical device distributors and strategic relationships for the marketing and selling of our Powerlink System
internationally. We depend on these distributors efforts to market our product, yet we are unable to control their efforts completely. In addition, we are unable to ensure that our distributors are complying all applicable laws regarding the
sales of our products. If our distributors fail to market and sell our products effectively and in compliance with applicable laws, our operating results and business may suffer substantially, or we may have to make significant additional
expenditures or concessions to market our products.

We are in a highly competitive market segment, which is subject to
rapid technological change. If our competitors are better able to develop and market products that are safer, more effective, less costly, easier to use, or otherwise more attractive than any products that we may develop, our ability to generate
revenue will be reduced or eliminated.

Our industry is highly competitive and subject to rapid and profound
technological change. Our success depends, in part, upon our ability to maintain a competitive position in the development of technologies and products for use in the treatment of AAA and other aortic disorders. We face competition from both
established and development stage companies. Many of the companies developing or marketing competing products are publicly traded or are divisions of publicly-traded companies, and these companies enjoy several competitive advantages, including:



| |  |  | greater financial and human resources for product development, sales and marketing and patent litigation;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | significantly greater name recognition;
| | - |  | ---------------------------------------



| |  |  | established relationships with physicians, customers and third-party payors;
| | - |  | ----------------------------------------------------------------------------



| |  |  | additional lines of products, and the ability to offer rebates or bundle products to offer greater discounts or incentives to gain a competitive
advantage;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | established sales and marketing, and distribution networks; and
| | - |  | ---------------------------------------------------------------



| |  |  | greater experience in conducting research and development, manufacturing, clinical trials, preparing regulatory submissions and obtaining regulatory
clearance or approval for products and marketing approved products.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our competitors may develop and patent
processes or products earlier than us, obtain regulatory clearance or approvals for competing products more rapidly than us, and develop more effective or less expensive products or technologies that render our technology or products obsolete or
non-competitive. We also compete with our competitors in recruiting and retaining qualified scientific, sales, and management personnel, establishing clinical trial sites and patient enrollment in clinical trials, as well as in acquiring
technologies and technology licenses complementary to our products or advantageous to our business. If our competitors are more successful than us in these matters, our business may be harmed.

Our dependence upon key personnel to operate our business puts us at risk of a loss of expertise if key personnel were to leave us.

We depend upon the experience and expertise of our executive management team. The competition for executives, as well
as for skilled product development and technical personnel and sales representatives, in the medical device industry is intense and we may not be able to retain or recruit the personnel we need. If we are not able to attract and retain existing and
additional highly qualified management, sales, regulatory, clinical and technical personnel, we may not be able to successfully execute our business strategy.

If we fail to properly manage our anticipated growth, our business could suffer.

We may experience periods of rapid growth and expansion, which could place a significant strain on our limited personnel, information technology systems, and other resources. In particular, the increase
in our direct sales force requires significant management and other supporting resources. Any failure by us to manage our growth effectively could have an adverse effect on our ability to achieve our development and commercialization goals. To
achieve our revenue goals, we must successfully increase production output as required by customer

demand. We may in the future experience difficulties in increasing production, including problems with production yields and quality control and assurance, component supply, and shortages of
qualified personnel. These problems could result in delays in product availability and increases in expenses. Any such delay or increased expense could adversely affect our ability to generate revenues. Future growth will also impose significant
added responsibilities on management, including the need to identify, recruit, train and integrate additional employees. In addition, rapid and significant growth will place a strain on our administrative and operational infrastructure. In order to
manage our operations and growth we will need to continue to improve our operational and management controls, reporting and information technology systems, and financial internal control procedures. If we are unable to manage our growth effectively,
it may be difficult for us to execute our business strategy and our operating results and business could suffer.

We
have a history of operating losses and may be required to obtain additional funds.

We have a history of operating
losses, and although we expect to generate positive cash flow from operations in 2010, we may not be able to continue to do so. Our cash requirements in the future may be significantly different from our current estimates and depend on many factors,
including:



| |  |  | the results of our commercialization efforts for the Powerlink System;
| | - |  | ----------------------------------------------------------------------



| |  |  | the need for additional capital to fund future development programs;
| | - |  | --------------------------------------------------------------------



| |  |  | the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | the establishment of high volume manufacturing and increased sales and marketing capabilities; and
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | our success in entering into collaborative relationships with other parties.
| | - |  | ----------------------------------------------------------------------------

To finance these activities, we may seek funds through borrowings or through additional rounds of financing, including private or public
equity or debt offerings and collaborative arrangements with corporate partners. We may be unable to raise funds on favorable terms, or at all. During the recent economic crisis, it has been difficult for many companies, particularly small cap
medical device companies, to obtain financing in the public markets or to obtain debt financing on commercially reasonable terms, if at all. In addition, the sale of additional equity or convertible debt securities could result in additional
dilution to our stockholders. If we borrow additional funds or issue debt securities, these securities could have rights superior to holders of our common stock, and could contain covenants that will restrict our operations. We might have to obtain
funds through arrangements with collaborative partners or others that may require us to relinquish rights to our technologies, product candidates or products that we otherwise would not relinquish. If we do not obtain additional resources, our
ability to capitalize on business opportunities will be limited, and the growth of our business will be harmed.

We rely
solely on an in-house process to manufacture our graft material for the Powerlink System, and any disruption in our ability to produce this material could delay or prevent us from producing the product for sale.

Currently, we rely solely on an in-house manufacturing process to produce graft material, which is a primary component for the Powerlink
System. Our reliance on a sole source exposes our operations to disruptions in supply caused by:



| |  |  | failure to comply with quality or regulatory requirements;
| | - |  | ----------------------------------------------------------



| |  |  | fire, flood or earthquake, or other natural disaster; and
| | - |  | ---------------------------------------------------------



| |  |  | a supply interruption in the underlying raw material for the process.
| | - |  | ---------------------------------------------------------------------

##### Table of Contents

Although we attempt to retain a significant stock of the graft material, the occurrence of
any of the above disruptions in supply or other unforeseen events that could cause a disruption in our process to manufacture graft material may cause us to halt or experience a disruption in manufacturing the Powerlink System. Because we do not
have alternative suppliers, our sales and operating results would be harmed in the event of a disruption.

We rely on a
single vendor to supply certain components for the Powerlink System, and any disruption in our supply could delay or prevent us from producing the product for sale.

Currently, we rely on certain vendors as a sole source to supply us with certain primary components for the Powerlink System. Our reliance
on a sole source supplier exposes our operations to disruptions in supply caused by:



| |  |  | failure to comply with regulatory requirements;
| | - |  | -----------------------------------------------



| |  |  | any strike or work stoppage;
| | - |  | ----------------------------



| |  |  | disruptions in shipping;
| | - |  | ------------------------



| |  |  | a natural disaster caused by fire, floods or earthquakes;;
| | - |  | ----------------------------------------------------------



| |  |  | a supply shortage experienced by our sole source suppliers; and;
| | - |  | ----------------------------------------------------------------



| |  |  | the fiscal health and manufacturing strength of our sole source suppliers.
| | - |  | --------------------------------------------------------------------------

Although we retain significant stock in sole source components, the occurrence of any of the above disruptions in supply or other unforeseen
events that could cause a disruption in supply from our sole source suppliers.

If we are unable to protect our
intellectual property, our business may be negatively affected.

The market for medical devices is subject to frequent
litigation regarding patent and other intellectual property rights. It is possible that our patents or licenses may not withstand challenges made by others or protect our rights adequately.

Our success depends in large part on our ability to secure effective patent protection for our products and processes in the United States
and internationally. We have filed and intend to continue to file patent applications for various aspects of our technology. However, we face the risks that:



| |  |  | we may fail to secure necessary patents prior to or after obtaining regulatory clearances, thereby permitting competitors to market competing products;
and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our already-granted patents may be re-examined, re-issued or invalidated.
| | - |  | -------------------------------------------------------------------------

We also own trade secrets and confidential information that we try to protect by entering into confidentiality agreements with other
parties. However, the confidentiality agreements may not be honored or, if breached, we may not have sufficient remedies to protect our confidential information. Further, our competitors may independently learn our trade secrets or develop similar
or superior technologies. To the extent that our consultants, key employees or others apply technological information to our projects that they develop independently or others develop, disputes may arise regarding the ownership of proprietary rights
to such information, and such disputes may not be resolved in our favor. If we are unable to protect our intellectual property adequately, our business and commercial prospects likely will suffer.

If we are unable to effectively manage our inventory held on consignment by our intended customers, we will not achieve our expected
results.

Our Powerlink System is sold on a consignment basis to certain hospitals which purchase our product as they
use it. In these consignment locations, we do not have physical possession of our products. We therefore must rely on information from our customers as well as periodic inspections by our sales personnel to determine when our products have been
used. Our efforts to strengthen our monitoring and management of consigned inventory may not be adequate to meaningfully reduce the risk of inventory loss. If we are not able to effectively manage appropriate consigned inventory levels, we may
suffer inventory losses which will reduce our operating results.

##### Table of Contents

We may face product liability claims that could result in costly litigation and
significant liabilities.

Manufacturing and marketing of our commercial products, and clinical testing of our products
under development, may expose us to product liability claims. Although we have, and intend to maintain, product liability insurance, the coverage limits of our insurance policies may not be adequate and one or more successful claims brought against
us may have a material adverse effect on our business and results of operations. Additionally, adverse product liability actions could negatively affect the reputation and sale of our products, our ability to obtain and maintain regulatory approval
for our products and may divert managements attention from other matters.

Our operations are currently conducted
at a single location that may be at risk from earthquakes or other natural disasters.

We currently conduct all of our
manufacturing, development and management activities at a single location in Irvine, California, near known earthquake fault zones. We have taken precautions to safeguard our facilities, including insurance, health and safety protocols, and off-site
storage of computer data. However, any future natural disaster, such as an earthquake, could cause substantial delays in our operations, damage or destroy our equipment or inventory, and cause us to incur additional expenses. A disaster could
seriously harm our business and results of operations. The insurance coverage we maintain may not be adequate to cover our losses in any particular case.

The price of our stock may fluctuate unpredictably in response to factors unrelated to our operating performance.

The stock market periodically experiences significant price and volume fluctuations that are unrelated to the operating performance of
particular companies. These broad market fluctuations may cause the market price of our common stock to drop. In particular, the market price of securities of small medical device companies, like ours, has been very unpredictable and may vary in
response to:



| |  |  | announcements by us or our competitors concerning technological innovations;
| | - |  | ----------------------------------------------------------------------------



| |  |  | introductions of new products;
| | - |  | ------------------------------



| |  |  | FDA and foreign regulatory actions;
| | - |  | -----------------------------------



| |  |  | developments or disputes relating to patents or proprietary rights;
| | - |  | -------------------------------------------------------------------



| |  |  | failure of our results of operations to meet the expectations of stock market analysts and investors;

Trading in our stock over the last twelve months has been limited, so investors may not be able to sell as much stock as they want at
prevailing prices.

The average daily trading volume in our common stock for the year ended December 31, 2009 was
approximately 190,000 shares. If limited trading in our stock continues, it may be difficult for investors to sell their shares in the public market at any given time at prevailing prices. Moreover, the market price for shares of our common stock
may be made more volatile because of the relatively low volume of trading in our common stock. When trading volume is low, significant price movement can be caused by the trading in a relatively small number of shares. Volatility in our common stock
could cause stockholders to incur substantial losses.

Some provisions of our charter documents and Delaware law may
make takeover attempts difficult, which could depress the price of our stock and inhibit your ability to receive a premium price for your shares.

Provisions of our amended and restated certificate of incorporation could make it more difficult for a third party to acquire control of our business, even if such change in control would be beneficial to
our stockholders. Our amended and restated

certificate of incorporation allows our board of directors to issue up to five million shares of preferred stock and to fix the rights and preferences of such shares without stockholder approval.
Any such issuance could make it more difficult for a third party to acquire our business and may adversely affect the rights of our stockholders. In addition, our board of directors is divided into three classes for staggered terms of three years.
We are also subject to anti-takeover provisions under Delaware law, each of which could delay or prevent a change of control. Together these provisions may delay, deter or prevent a change in control of us, adversely affecting the market price of
our common stock.

We do not anticipate declaring any cash dividends on our common stock.

We have never declared or paid cash dividends on our common stock and do not plan to pay any cash dividends in the near future. Our current
policy is to retain all funds and any earnings for use in the operation and expansion of our business. The payment of cash dividends by us is restricted by our revolving credit facility, which contains restrictions prohibiting us from paying any
cash dividends without the lenders prior approval. If we do not pay dividends, our stock may be less valuable to you because a return on your investment will only occur if our stock price appreciates.

|Item 2. | Properties
|------- | ----------

Currently, we
lease two adjacent facilities aggregating approximately 43,500 square feet in Irvine, California under separate lease agreements that expire in August 2011 and may be renewed for two additional twelve month periods, at our option. We believe that
our current facilities will be adequate and suitable for our operations through the current lease term.



|Item 3. | Legal Proceedings
|------- | -----------------

We are
involved in various claims and legal proceedings of a nature considered normal to our business, including product liability, intellectual property, employment and other matters.

We are involved in litigation with Cook Medical Incorporated, or Cook, alleging that the we infringe two of Cooks patents, one of
which was granted in 1991 and the other in 1998. The lawsuit was filed by Cook in the United States District Court, Southern District of Indiana, on October 8, 2009. In December 2009, the United States Patent Office, or PTO, granted our request
for a reexamination of the two patents asserted by Cook in the lawsuit, and in January 2010, the United States District Court ordered that the lawsuit be stayed pending the outcome of the patent reexaminations. In February 2010, the PTO completed
its re-examination process and concluded that one of the two patents in question was invalid, while the validity of the second was upheld. At this date, the legal proceedings remain stayed.

Dividend Policy

We have never paid any dividends. We currently intend to retain all earnings, if any, for use in the expansion of our business and therefore do not anticipate paying any dividends in the foreseeable
future. Additionally, the terms of our credit facility prohibit us from paying cash dividends without the lenders consent.

|Item 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

The following discussion and analysis should be read in conjunction with Selected Financial Data and our consolidated financial
statements and the related notes included in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the
forward-looking statements as a result of various factors including the risks we discuss in Item 1A of Part I, Risk Factors and elsewhere in this Annual Report on Form 10-K.

Overview

We are engaged in the development, manufacturing, marketing and sale of minimally invasive treatments for aortic disorders. Our primary focus is the marketing and sale of the Powerlink System, a catheter-based alternative treatment to
surgery for AAA. Beginning in 2009, our sole source of revenue is sales of the Powerlink System. Prior to 2009, we also generated license revenue from the licensing of our technology from our previous line of business.

For the year ended December 31, 2009, we had net sales of $52.4 million, which was an increase of approximately 39% from the year ended
December 31, 2008, and incurred a net loss of $2.4 million. As of December 31, 2009, we had an accumulated deficit of approximately $146.2 million. We have experienced year over year sales growth since the commercial launch of the Powerlink System
in the United States in 2004. We now sell our products in the United States, Europe, Asia and South America.

As a result of
our history of operating losses, we had limited resources with which to develop additional products beyond the Powerlink System. However, in 2009 we generated approximately $5 million of cash flow from operations and received approximately $14.7
million net proceeds from a public offering of our common stock, as well as entered into a new long term credit facility whereby we may borrow up to $10 million. Based on this increase in capital resources, we have the ability to increase our
research and development efforts to develop new technologies for the treatment of aortic disorders, which we believe is vital to the future growth of our business.

Summary of Accounting Policies and Use of Estimates

The preparation
of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosure of
contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to collectibility of customer accounts, whether the cost of inventories can be recovered, the value assigned to and estimated useful life of
intangible assets, the realization of tax assets and estimates of tax liabilities, contingent liabilities and the potential outcome of litigation. We base our estimates on historical experience and on various other assumptions that are believed to
be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions.

##### Table of Contents

The following critical accounting policies and estimates were used in the preparation of the
consolidated financial statements:

Revenue Recognition and Accounts Receivable

We comply with the revenue recognition guidelines in SEC Staff Accounting Bulletin No. 104, Revenue Recognition. We
recognize revenue when all of the following criteria are met:



| |  |  | Persuasive evidence of an arrangement exists;
| | - |  | ---------------------------------------------



| |  |  | The sales price is fixed or determinable;
| | - |  | -----------------------------------------



| |  |  | Collection of the relevant receivable is probable at the time of sale; and
| | - |  | --------------------------------------------------------------------------



| |  |  | Products have been shipped or used and the customer has taken ownership and assumed risk of loss.
| | - |  | -------------------------------------------------------------------------------------------------

For domestic sales, we generally recognize revenue upon completion of a procedure, when our product is implanted in a patient. For
international sales, we recognize revenue at the time of shipment of our products to a distributor.

In the past, we have
earned royalty revenue, which was included in license revenue in the consolidated statement of operations, as a result of the sale of product rights and technologies to third parties. Royalties were recognized upon the sale of products subject to
the royalty by the third party.

We do not offer rights of return and we have no post delivery obligations other than our
specified warranty.

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our
customers to make required payments. These estimates are based on our review of the aging of customer balances, correspondence with the customer, and the customers payment history. If additional information becomes available to us indicating
the financial condition of the customer is deteriorating, additional allowances may be required.

Inventories

We write down our inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost
of inventory and the estimated realizable value based upon assumptions about future demand, as driven by economic and market conditions, and the products shelf life. If actual demand, or economic or market conditions are less favorable than
those projected by management, additional inventory write-downs may be required.

Goodwill, Intangible Assets and
Long-Lived Assets

We record an impairment charge, or expense, for long-lived assets whenever events or changes in
circumstances indicate that the value recorded for the asset may not be recoverable. Future changes in operations could cause us to write down the asset value and record an expense to better reflect our current estimate of its value. Goodwill and
indefinite-lived intangible assets are tested for impairment annually, or more frequently if events or changes in circumstances indicate that the goodwill or indefinite-lived intangible assets are impaired. Factors that may impact whether there is
potential goodwill impairment include a significant decrease in our stock price and our evaluation of a control premium that may be used when estimating our total fair value. Our stock price may decline, or other factors may arise, which could
result in goodwill impairment in future periods. Factors that may impact whether there is a potential impairment to our indefinite-lived intangible assets include legal and regulatory considerations.

Income Taxes

We record the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards. We have
recorded a full valuation allowance to reduce our deferred tax assets to zero, because we believe that, based upon a number of factors, it is more likely than



24

##### Table of Contents

not that the deferred tax assets will not be realized. If we were to determine that we would be able to realize our deferred tax assets in the future, an adjustment to the valuation allowance on
our deferred tax assets would increase net income in the period such determination was made.

Stock-based compensation

We recognize compensation expense over a stock option awards vesting period based on the awards fair value at the
date of grant. We use the Black-Scholes option pricing model to value stock option grants. The fair value for awards that are expected to vest is then amortized on a straight-line basis over the requisite service period of the award, which is
generally the option vesting term. The amount of expense attributed is net of an estimated forfeiture rate, which is updated as appropriate. This option pricing model requires the input of highly subjective assumptions, including the expected
volatility of our common stock, pre-vesting forfeiture rate and the options expected life. The financial statements include such amounts based on our best estimates and judgments.

Results of Operations

Comparison of Years Ended December 31, 2009 and 2008

Product
Sales. Sales increased 39% to $52.4 million in 2009 from $37.6 million in 2008 primarily due to the increased productivity of our sales force, the introduction of new products including Powerlink XL, our suprarenal proximal extension, and the
IntuiTrak delivery system, and increased physician acceptance of the Powerlink System. Domestic sales increased from $31.9 million to $43.7 million, and sales to distributors outside the United States increased from $5.7 million in 2008 to $8.8
million in 2009. This increase was driven primarily by the introduction of IntuiTrak to most of our international distributors. Additionally, we had higher sales to our distributors in South America and Japan and an initial sale generating stocking
order from our distributor in China.

We expect that product sales will increase in 2010 by an estimated 18% to 26% from 2009,
to $62 million to $66 million. Based on the timing of new product launches and continued improvements in sales force productivity, we expect that the majority of the revenue growth will be weighted in the second half of the year. Outside the United
States, we expect growth in each of our major markets of Europe, Asia, and South America.

Cost of Product Revenue.The
cost of product revenue, which includes labor, overhead, materials and parts, rent, depreciation, small tools and supplies, samples for destructive testing, and utilities, among other items, increased 27% from $10.4 million in 2008 to $13.2 million
in 2009. The increase is primarily attributable to an increase in the volume of Powerlink System sales, partially offset by efficiencies in our manufacturing process.

Gross Profit.Gross profit increased 44% to $39.3 million in 2009 from $27.3 million in 2008. The increase in gross profit resulted from higher product sales in 2009 as compared to 2008 and from a
favorable product mix due to new product introductions, which have a higher average selling price. Gross profit as a percentage of revenue increased to 75% in 2009 from 72% in 2008 for these reasons.

We believe that gross profit dollars will increase in 2010 due to higher commercial sales of the Powerlink System both in and outside of the
United States. We also expect that gross profit as a percentage of product revenues will increase due to efficiencies from higher manufacturing volumes required to support sales growth.

Research, Development and Clinical.Research, development and clinical expenses increased by 8% to $6.6 million from $6.1 million in
2008. The increase primarily resulted from costs associated with the development of new products for the treatment of aortic disorders.

We expect that these expenses will significantly increase in 2010 as we pursue opportunities to develop additional new products for the treatment of aortic disorders and costs associated with the
bilateral percutaneous clinical trial. We also expect expenses to increase in subsequent years as we increase our new product development activities.

##### Table of Contents

Marketing and Sales.Marketing and sales expenses increased by 11% to $26.5 million
from $23.8 million in 2008. This increase was due to higher sales commission payouts on the 37% growth in domestic sales revenue and an increase in marketing efforts related to our product launches in 2009.

We expect that marketing and sales expense will increase in 2010 due to higher commission expense on the expected increase in sales and due
to higher compensation costs associated with the expected increase in the number of sales territories by approximately 30% by the end of 2010.

General and Administrative.General and administrative expenses decreased by 10% to $8.6 million from $9.5 million in 2008. The decrease was primarily due to $700,000 in costs associated with our
chief executive officer succession, which occurred in May 2008, and significant legal fees that occurred in 2008. These reductions were partially offset by higher stock based compensation charges and incentive comepensation accruals based on
performance metrics in 2009. We expect that general and administrative expenses in 2010 will be approximately unchanged from 2009.

Other Income/(expense).Other income/(expense) decreased 267% to ($92,000) in 2009 from $55,000 in 2008. An increase in interest income was offset by expenses related to interest expense incurred in the first three quarters of 2009.

We expect that other income will increase due to interest income on a higher average cash balance in 2010, and lower interest
expense.

Comparison of Years Ended December 31, 2008 and 2007

Product Sales. Sales increased 39% to $37.6 million in 2008 from $27.0 million in 2007 primarily due to the increased productivity of
our domestic field sales personnel, and the introduction of our suprarenal proximal extensions and Powerlink XL products. Domestic sales increased from $23.0 million to $31.9 million, and sales to distributors outside the United States increased
from $4.0 million in 2007 to $5.7 million in 2008. This increase was primarily due to sales to our distributor in Japan, as well as an increase in sales to distributors in South America.

License Revenue.License revenue decreased 96% to $33,000 in 2008 from $754,000 in 2007. License revenue from Abbott remained at the
contractual minimum level of $250,000 for 2007, and expectedly declined sharply in 2008 as the minimum royalty provision of the agreement expired at December 31, 2007. The license expired and was fully paid up in June 2008. Additionally in
2007, due to our licensing agreement with BioLucent, we received $504,000 in royalties and fees, including a one-time payment of $500,000 in exchange for a fully paid up license to certain of our patents in a certain field of use. Beginning
January 1, 2008, sales of our Powerlink System were our only material source of revenue.

Cost of Product Revenue.The cost of product revenue, which includes labor, overhead, materials and parts, rent, depreciation, small tools and supplies, samples for destructive testing, and utilities, among other items, decreased 2% to $10.4 million from $10.5 million
in 2007. This decrease is directly attributable to the substitution of lower-cost in-house produced graft material in a majority of the products sold in 2008.

Gross Profit.Gross profit increased 58% to $27.3 million in 2008 from $17.2 million in 2007. The increase in gross profit resulted from higher product sales in 2008 as compared to 2007 and a
reduction in the per unit cost of product due to substitution of lower-cost in-house produced graft material in a majority of the products sold in 2008. Gross profit as a percentage of revenue increased to 72% in 2008 from 62% in 2007 for these
reasons.

Research, Development and Clinical.Research, development and clinical expenses decreased by 5% to $6.1
million from $6.4 million in 2007. The decrease primarily resulted from lower costs associated with clinical trials in the 2008 period. We recorded $236,000 in 2008 and $417,000 in 2007, of stock compensation expense.

Marketing and Sales.Marketing and sales expenses increased by 18% to $23.8 million from $20.1 million in 2007. This increase was due
to higher sales commission payouts on the 39% growth in domestic sales revenue, severance payments, and the implementation of an in-depth sales training program. We recorded $1.0 million in 2008 and $878,000 in 2007, respectively, of stock
compensation expense.

##### Table of Contents

General and Administrative.General and administrative expenses increased by 48% to
$9.5 million from $6.4 million in 2007. The increase was due primarily to increases in patent and legal fees, settlement of the legal dispute with Cook, our chief executive officer succession process, and our analysis and response to the unsolicited
acquisition proposal from Elliott Associates. In addition, stock based compensation expense totaled $1.4 million in 2008 as compared to $894,000 in 2007.

Termination of Supply Agreement. Termination of supply agreement expense was $550,000 in 2007. The expense was due to the third amendment to our supply agreement for ePTFE graft material with Bard
Peripheral, dated September 21, 2007, which reduced the minimum purchase requirement for the 2007 year from $2.9 million to $2.2 million, and wherein both parties agreed to terminate the agreement on December 31, 2007. In consideration for
the reduction in the minimum purchase requirement for the 2007 year, we paid $550,000 to Bard Peripheral.

Other Income.Other income decreased 95% to $55,000 from $1.1 million in 2007. The decrease in other income was primarily the result of a realized gain of $412,000 on our investment in BioLucent in 2007, lower interest income, and higher interest expense in
2008 due to drawing down on the term loan and revolving line of credit with Silicon Valley Bank in September 2008.

Liquidity and Capital Resources

For the years ended December 31, 2009 and 2008, we incurred net
losses of $2.4 million and $12.0 million, respectively. As of December 31, 2009, we had an accumulated deficit of approximately $146.2 million. Historically, we have relied on the sale and issuance of equity securities to provide a significant
portion of funding for our operations. In August 2009, we completed a sale of our common stock that resulted in net proceeds of approximately $14.8 million. In 2009, we began to generate positive cash flows from operations for the first time in our
history.

In October 2009, we entered into a revolving credit facility with Wells Fargo Bank, National Association, or Wells,
whereby we may borrow up to $10.0 million. All outstanding amounts under the credit facility bear interest at a variable rate equal to the greater of 90 day LIBOR, the federal funds rate, or the lenders prime rate, plus 1.25%, which is payable
on a monthly basis. The unused portion is subject to an unused revolving line facility fee, payable quarterly, in arrears, on a calendar year basis, in an amount equal to 0.2% per annum of the average unused portion of the revolving line, as
determined by Wells. The credit facility also contains customary covenants regarding operations of our business and financial covenants relating to ratios of current assets to current liabilities and tangible net worth during any calendar quarter
and is collateralized by all of our assets with the exception of our intellectual property. All amounts owing under the credit facility will become due and payable on April 30, 2012. As of December 31, 2009, we did not have any outstanding
borrowings under this credit facility and we were in compliance with all covenants.

At December 31, 2009, we had cash
and cash equivalents of $24.1 million. We generated $5.0 million of operating cash flow in 2009. We believe that our current cash balance, in combination with cash flows from operations and borrowings available under our credit facility, will be
sufficient to meet anticipated cash needs for operating and capital expenditures for the foreseeable future. If we do not realize expected revenue and gross profit margin levels, are unable to manage our operating expenses in line with our revenues,
cannot maintain our days sales outstanding accounts receivable level, we may not continue to achieve positive cash flow from operations, we may need to obtain additional financing.

We believe that the future growth of our business will depend upon our ability to successfully develop new technologies for the treatment of
aortic disorders and bring these technologies to market, and to increase the size and productivity of our direct sales force. In order to achieve these objectives, we may need to seek additional sources of financing. In the event that we require
additional funding, we will attempt to raise the required capital through either debt or equity arrangements.

The timing and
amount of our future capital requirements will depend on many factors, including:



| |  |  | the need for additional capital to fund future development programs or sales force expansion;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | the need for additional capital to fund business development acquisition(s);
| | - |  | ----------------------------------------------------------------------------



| |  |  | our requirements for additional facility space or manufacturing capacity;
| | - |  | -------------------------------------------------------------------------

##### Table of Contents

| |  |  | our requirements for additional information technology infrastructure and systems; and
| | - |  | --------------------------------------------------------------------------------------



| |  |  | adverse outcome(s) from current or future litigation and the cost to defend such litigation.
| | - |  | --------------------------------------------------------------------------------------------

If we are required to obtain additional financing, we may not be able to do so on acceptable terms, if at all. Even if we are able to obtain
such financing it may cause substantial dilution for our stockholders, in the case of an equity financing, or may contain burdensome restrictions on the operations of our business, in the case of debt financing.

Accounts Receivable.Trade accounts receivable, net, increased 31% to $8.3 million at December 31, 2009 from $6.4 million at
December 31, 2008. The increase was due to the 39% increase in product sales in 2009.

Inventories.Inventories
decreased 22% to $5.5 million at December 31, 2009 from $7.1 million at December 31, 2008. The decrease was primarily the result of a lower cost basis of the ePTFE graft material and the complete transition to the Intuitrak product line.

Accounts Payable and Accrued Expenses.Accounts payable and accrued expenses increased 34% to $7.2 million at
December 31, 2009 from $5.4 million at December 31, 2008. The increase is primarily attributable higher accruals in 2009 related to incentive bonus and commission programs and higher accrued legal services

Cash Provided by/(Used in) Operations.In 2009, cash provided by operations was $5.0 million as compared to cash used in operations
of ($6.0) in 2008. The change was primarily attributed to a higher sales volume and improved inventory turns.

Cash Used in
Investing Activities.Cash used in investing activities decreased to $98,000 for the year ended December 31, 2009 from $447,000 for the year ended December 31, 2008. The change was due to the elimination of a restricted cash
requirement of $500,000 from our primary lender.

Cash Provided by Financing Activities.Cash provided by financing
activities was $11.5 million for the year ended December 31, 2009 from $5.5 million for the year ended December 31, 2008, primarily as a result of our equity offering of $14.8 million in 2009. In 2008, we borrowed $5.0 million, which was
repaid in 2009.

Off-Balance Sheet Arrangements

We do not maintain any off-balance sheet arrangements.

Commitments

As of December 31, 2009, expected future cash payments

Recent Accounting
Pronouncements

In December 2007, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards
Codification, or ASC, FASB ASC topic 805, Business Combinations (ASC 805). ASC 805 is a revision to previously existing guidance on accounting for business combinations. The statement retains the fundamental concept of the purchase
method of accounting, and introduces new requirements for the recognition and measurement of assets acquired, liabilities assumed and noncontrolling interests. The statement is effective for fiscal years beginning after December 15, 2008. As of
December 31, 2009, the adoption of ASC 805 had no impact on our consolidated financial statements.

##### Table of Contents

In December 2007, the FASB issued FASB ASC topic 810, Consolidation (ASC 810).
ASC 810 requires that noncontrolling interests be reported as stockholders equity. ASC 810 also establishes a single method of accounting for changes in a parents ownership interest in a subsidiary as long as that ownership change does not
result in deconsolidation. ASC 810 is required to be applied prospectively in 2009, except for the presentation and disclosure requirements which are to be applied retrospectively. The statement is effective for fiscal years beginning after
December 15, 2008. As of December 31, 2009, the adoption of ASC 810 had no impact on our consolidated financial statements.

In April 2008, the FASB issued FASB ASC topic 350, Intangibles-Goodwill and Other (ASC 350), which amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of
a recognized intangible asset under FASB Statement No. 142, Goodwill and Other Intangible Assets. ASC 350 allows an entity to use its own historical experience in renewing or extending similar arrangements, adjusted for specified
entity-specific factors, in developing assumptions about renewal or extension used to determine the useful life of a recognized intangible asset and it is effective for fiscal years and interim periods beginning after December 15, 2008.
Additional disclosures are required to enable financial statement users to assess the extent to which the expected future cash flows associated with the asset are affected by the entitys intent and/or ability to renew or extend the
arrangement. The guidance for determining the useful life of a recognized intangible asset is to be applied prospectively to intangible assets acquired after the effective date. The disclosure requirements are to be applied prospectively to all
intangible assets recognized as of, and subsequent to, the effective date. As of December 31, 2009, the adoption of ASC 350 had no impact on our consolidated financial statements.

In June 2008, the FASB issued FASB ASC topic 260, Earnings Per Share (ASC 260). ASC 260 clarifies that share-based payment
awards that entitle their holders to receive nonforfeitable dividends before vesting should be considered participating securities. As participating securities, these instruments should be included in the calculation of basic earnings per share. ASC
260 is effective for financial statements issued for fiscal years beginning after December 15, 2008, as well as interim periods in those years. Once effective, all prior period earnings per share data presented must be adjusted retrospectively
and early application is not permitted. As of December 31, 2009, the adoption of ASC 260 had no impact on our consolidated financial statements.



|Item 7A. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

We do not believe that we currently have material exposure to interest rate, foreign currency exchange rate or other relevant market risks.



29



---

##### Table of Contents

Interest Rate and Market Risk.Our exposure to market risk for changes in interest
rates relates primarily to our revolving credit facility. Under our revolving credit facility all outstanding amounts bear interest at a variable rate equal to the greater of 90 day LIBOR, the federal funds rate, or the lenders prime rate,
plus 1.25%. As of December 31, 2009, we had no amounts outstanding under the revolving line of credit. We may be exposed to market risk with respect to the revolving line of credit due to changes in interest rates.

We do not use derivative financial instruments in our investment portfolio. We place our investments with high credit quality issuers and,
by policy, limit the amount of credit exposure to any one issuer. We are averse to principal loss and try to ensure the safety and preservation of our invested funds by limiting default risk, market risk, and reinvestment risk. We attempt to
mitigate default risk by investing in only the safest and highest credit quality securities and by constantly positioning our portfolio to respond appropriately to a significant reduction in a credit rating of any investment issuer or guarantor. At
December 31, 2009, our investment portfolio consisted of money market instruments.

Foreign Currency Transaction Risk.We do not currently have material foreign currency exposure as the majority of our assets are denominated in U.S. currency and our foreign-currency based transaction exchange risk is not material. For the years ended December 31, 2009,
2008, and 2007, we recorded ($49,000), $194,000, and $51,000, respectively, of foreign currency transaction gains (losses).

Managements Report on Internal Control Over Financial Reporting

Our management is responsible for
establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our internal control over financial reporting is
a process designed to provide reasonable assurance regarding the reliability of the financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. This process
includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that
transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts

and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the internal control over financial reporting to future periods are subject to
risk that the internal control may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2009. In making this assessment, it used the criteria set forth by the Committee of
Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework. Based on our assessment, we have concluded that, as of December 31, 2009, our internal control over financial reporting was effective based on those
criteria.

##### Table of Contents

The effectiveness of our internal control over financial reporting as of December 31,
2009 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report, which is included herein.

Disclosure controls and procedures

We carried out an evaluation,
under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures as of December 31, 2009, pursuant to Rules
13a-15(e) and 15d-15(e) under the Exchange Act. Based on that evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures, as of such date, were effective.

Changes in internal control over financial reporting

There has been no change in our internal control over financial reporting during the fourth fiscal quarter that has materially affected, or
is reasonably likely to materially affect, our internal control over financial reporting.

Supplemental Stock Option Plan

This stock option plan was used to provide compensation to non-employees, typically as
part of a consulting services arrangement. The plan authorized the issuance of non-qualified stock options only. We account for non-employee stock-based awards, in which goods or services are the consideration received for the stock options issued,
in accordance with the provisions of SFAS No. 123 and related interpretations. (See Note 1 and 11 to the consolidated financial statements for additional information on recognition of expense associated with non-employee option grants under the
1997 Supplemental Stock Option Plan).

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Endologix, Inc.:

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Endologix, Inc. and its
subsidiaries at December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2009 in conformity with accounting principles generally accepted in the
United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2), presents fairly, in all material respects, the information set forth therein when read in conjunction
with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal
ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedule, for maintaining
effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A.
Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with
the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and
whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also
included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that,
in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject
to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

1. Business, Basis of Presentation and Summary of Critical
Accounting Policies

Business and Basis of Presentation

Endologix, Inc. (the Company) was incorporated in California in March 1992 and reincorporated in Delaware in June 1993. In
January 1999, the Company merged with privately held Radiance Medical Systems, Inc. (former Radiance), and changed its name to Radiance Medical Systems, Inc. In May 2002, the Company merged with privately held Endologix, Inc., and
changed its name to Endologix, Inc.

Since the merger in May 2002, the Company has been engaged in the development,
manufacture, sales and marketing of minimally invasive therapies for the treatment of vascular disease. The Companys primary focus is the development of the Powerlink System, a catheter-based alternative treatment for abdominal aortic
aneurysms, or AAA. AAA is a weakening of the wall of the aorta, the largest artery of the body.

The consolidated financial
statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany transactions have been eliminated in consolidation. The Company operates in a single business segment.

Liquidity and Capital Resources

The accompanying financial statements have been prepared assuming the Company will continue as a going concern. For the years ended December 31, 2009, 2008, and 2007, the Company incurred net losses
of $2,434, $11,992 and $15,075, respectively. As of December 31, 2009, the Company had an accumulated deficit of $146,164. The Company believes that its continued growth, gross margins, expense controls, and its current cash and cash
equivalents balance, in combination with cash flows from operations and borrowings available under its credit facility, will be sufficient to fund ongoing operations through at least December 31, 2010.

In the event that the Company requires additional funding to continue operations or to fund future development programs, it will attempt to
raise the required capital through either debt or equity arrangements. The Company cannot provide any assurance that the required capital would be available on acceptable terms, if at all, or that any financing activity would not be dilutive to its
current stockholders. If the Company is not able to raise additional funds, it may be required to significantly curtail its operations and this would have an adverse effect on its financial position, results of operations and cash flows. The
financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Summary
of Accounting Policies and Use of Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going
basis, the Company evaluates its estimates, including those related to collectibility of customer accounts, whether the cost of inventories can be recovered, the value assigned to and estimated useful life of intangible assets, the realization of
tax assets and estimates of tax liabilities, contingent liabilities and the potential outcome of litigation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions.

Cash and Cash Equivalents

Cash and cash equivalents includes cash on hand, demand deposits and money market funds with original maturities of three months or less from
the date of purchase.

Accounts Receivables

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the
Companys best estimate of the amount of probable credit losses in existing accounts receivable. The Company determines the allowance based on historical write-off experience. The Company reviews the allowance for doubtful accounts monthly.
Past due balances over 90 days and over a specified amount are reviewed individually for collectibility. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.

Inventories

The Company values inventory at the lower of the actual cost to purchase or manufacture the inventory or the market value for such inventory. Cost is determined on the first-in, first-out method. The
Company regularly reviews inventory quantities in process and on hand and records a provision for obsolete inventory based on actual loss experience and a forecast of product demand compared to the remaining shelf life.

Property and Equipment

Property and equipment are stated at cost and depreciated on a straight-line basis over the estimated useful lives of the assets, with the exception of the Companys in-house ePTFE manufacturing
equipment, which is depreciated by a per unit produced basis and approximates a six year useful life. Leasehold improvements are amortized over the term of the lease or the estimated useful life of the asset, whichever is shorter. Maintenance and
repairs are expensed as incurred while renewals or betterments are capitalized. Upon sale or disposition of property and equipment, any gain or loss is included in the statement of operations. The estimated useful lives for furniture and equipment
range from three to seven years and the estimated useful life for leasehold improvements is five years.

Intangible Assets

Goodwill and other intangible assets with indefinite lives are not subject to amortization but are tested for impairment
annually or whenever events or changes in circumstances indicate that the asset might be impaired. The Company most recently performed its annual impairment analysis as of June 30, 2009 and will continue to test for impairment annually as of
June 30. No impairment was indicated.

The developed technology is being amortized over its estimated useful life of 10
years.

Long-Lived Assets

Long-lived assets and intangible assets with determinate lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
The Company evaluates potential impairment by comparing the carrying amount of the asset with the estimated undiscounted future cash flows associated with the use of the asset and its eventual disposition. Should the review indicate that the asset
is not recoverable, the Companys carrying value of the asset would be reduced to its estimated fair value, which is measured by future discounted cash flows.

Fair Value of Financial Instruments

The carrying amount of all financial instruments approximates fair value because of the short maturities of the instruments.

Concentrations of Credit Risk and Significant Customers

The Company maintains its cash and cash equivalents in deposit accounts and in money market securities administered by a major financial institution.

The Company sells its products primarily to hospitals and distributors worldwide. The Company performs credit evaluations of its
customers financial condition and generally does not require collateral from customers. Management believes that an adequate allowance for doubtful accounts has been provided.

No single customer accounted for more than 10% of the Companys total revenue in 2009, 2008, and 2007.

As of December 31, 2009 and December 31, 2008, no single customer accounted for more than 10% of the Companys accounts
receivable balance.

Product Sales by Geographic Region

The Company had product sales by region, based on where the Company ships the product, as follows:

Revenue Recognition

The Company recognizes revenue when all of the following criteria are met:



| |  |  | Persuasive evidence of an arrangement exists;
| | - |  | ---------------------------------------------



| |  |  | The sales price is fixed or determinable;
| | - |  | -----------------------------------------



| |  |  | Collection of the relevant receivable is probable at the time of sale; and
| | - |  | --------------------------------------------------------------------------



| |  |  | Products have been shipped or used and the customer has taken ownership and assumed risk of loss.
| | - |  | -------------------------------------------------------------------------------------------------

For domestic sales, the Company generally recognizes revenue upon completion of a procedure, when the product is implanted in a patient. For
international sales, the Company recognizes revenue at the time of shipment of the products to a distributor.

From time to
time, the Company may earn royalty revenue, from the licensing of its technology, which is included in license revenue in the consolidated statement of operations, as a result of the sale of product rights and technologies to third parties.
Royalties are recognized upon the sale of products subject to the royalty, by the third party. Currently, the Company is not receiving royalty revenue.

The Company does not offer rights of return or price protection and has no post delivery
obligations other than its specified warranty.

Shipping Costs

Shipping costs billed to customers are included in revenue with the related costs in costs of goods sold.

Foreign Currency

The assets and liabilities of foreign subsidiaries are translated at the rates of exchange at the balance sheet date. The income and expense items of these subsidiaries are translated at average monthly rates of exchange. The resulting
translation gains and losses are included as a component of accumulated other comprehensive income on the consolidated balance sheet. Gains and losses resulting from foreign currency transactions, which are denominated in a currency other than the
respective entitys functional currency are included in the consolidated statement of operations.

Income Taxes

The Company records the estimated future tax effects of temporary differences between the tax basis of assets and liabilities
and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards. It has recorded a full valuation allowance to reduce its deferred tax assets to zero, because the Company believes that, based upon a number
of factors, it is more likely than not that the deferred tax assets will not be realized. If the Company were to determine that it would be able to realize their deferred tax assets in the future, an adjustment to the valuation allowance on its
deferred tax assets would increase net income in the period such determination was made.

Net Loss Per Share

Net loss per common share is computed using the weighted average number of common shares outstanding during the periods
presented. Because of the net losses during the years ended December 31, 2009, 2008, and 2007, options to purchase the common stock of the Company were excluded from the computation of net loss per share because the effect would have been
antidilutive.

If anti-dilutive stock options were included, the number of shares used to compute net loss per share would
have been increased by approximately 3,389,000 shares, 4,802,000 shares, and 2,874,000 shares, for the years ended December 31, 2009, 2008 and 2007, respectively. Of these amounts, 2,422,000, 4,746,000, and 2,678,000 shares had an exercise
price above the average closing price for the years ended December 31, 2009, 2008, and 2007, respectively.

Research
and Development Costs

Research and development costs are expensed as incurred.

Comprehensive Income (Loss)

Comprehensive income (loss) includes unrealized holding gains and losses and other items that have been previously excluded from net income
(loss) and reflected instead in stockholders equity. Comprehensive income (loss) includes net loss, the effect of foreign currency translation adjustments, and unrealized holding gains (losses) on marketable securities classified as
available-for-sale.

Product Warranty

Within six months of shipment, certain customers may request replacement of products they receive that do not meet the manufacturers product specifications. No other warranties are offered and the
Company disclaims responsibility for any consequential or incidental damages associated with the use of the products. Historically, the Company has not experienced a significant amount of costs as a result of its product warranty policy.

Recent Accounting Pronouncements

In December 2007, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Codification, or ASC, FASB ASC topic 805, Business Combinations (ASC 805). ASC 805 is a
revision to previously existing guidance on accounting for business combinations. The statement retains the fundamental concept of the purchase method of accounting, and introduces new requirements for the recognition and measurement of assets
acquired, liabilities assumed and noncontrolling interests. The statement is effective for fiscal years beginning after December 15, 2008. As of December 31, 2009, the adoption of ASC 805 had no impact on the Companys consolidated
financial statements.

In December 2007, the FASB issued FASB ASC topic 810, Consolidation (ASC 810). ASC 810
requires that noncontrolling interests be reported as stockholders equity. ASC 810 also establishes a single method of accounting for changes in a parents ownership interest in a subsidiary as long as that ownership change does not result in
deconsolidation. ASC 810 is required to be applied prospectively in 2009, except for the presentation and disclosure requirements which are to be applied retrospectively. The statement is effective for fiscal years beginning after December 15,
2008. As of December 31, 2009, the adoption of ASC 810 had no impact on the Companys consolidated financial statements.

In April 2008, the FASB issued FASB ASC topic 350, Intangibles-Goodwill and Other (ASC 350), which amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of
a recognized intangible asset under FASB Statement No. 142, Goodwill and Other Intangible Assets. ASC 350 allows an entity to use its own historical experience in renewing or extending similar arrangements, adjusted for specified
entity-specific factors, in developing assumptions about renewal or extension used to determine the useful life of a recognized intangible asset and it is effective for fiscal years and interim periods beginning after December 15, 2008.
Additional disclosures are required to enable financial statement users to assess the extent to which the expected future cash flows associated with the asset are affected by the entitys intent and/or ability to renew or extend the
arrangement. The guidance for determining the useful life of a recognized intangible asset is to be applied prospectively to intangible assets acquired after the effective date. The disclosure requirements are to be applied prospectively to all
intangible assets recognized as of, and subsequent to, the effective date. As of December 31, 2009, the adoption of ASC 350 had no impact on the Companys consolidated financial statements.

In June 2008, the FASB issued FASB ASC topic 260, Earnings Per Share (ASC 260). ASC 260 clarifies that share-based payment
awards that entitle their holders to receive nonforfeitable dividends before vesting should be considered participating securities. As participating securities, these instruments should be included in the calculation of basic earnings per share. ASC
260 is effective for financial statements issued for fiscal years beginning after December 15, 2008, as well as interim periods in those years. Once effective, all prior period earnings per share data presented must be adjusted retrospectively
and early application is not permitted. As of December 31, 2009, the adoption of ASC 260 had no impact on the Companys consolidated financial statements.

2. License Agreements

In June 1998, the Company signed a technology license agreement with Guidant granting Guidant the right to manufacture and distribute stent
delivery products using the Companys Focus technology. Under the agreement, the Company was entitled to receive certain milestone payments based upon the transfer of the technology to Guidant, and royalty payments based upon the sale of
products using the Focus technology. In April 2006, Abbott acquired Guidants vascular business, including all rights and obligations under the license. For the years ended December 31, 2008 and, 2007, the Company recorded $33 and $250,
respectively, in royalties under the agreement. This royalty agreement expired in June of 2008, at which time Abbott acquired a fully paid up license for the underlying technology.

In September 2006, the Company licensed to BioLucent, Inc., a privately held medical device company, rights under certain patents held by
the Company. In September 2007, Hologic, Inc. purchased BioLucent, Inc. Pursuant to this acquisition, the Company had the option to continue the royalty arrangement or to receive a one-time cash payment in exchange for a fully-paid up license. The
Company elected to receive the one-time payment of $500. For the year ended December 31, 2007, the Company recorded $504 in royalties under the agreement and all payments were received.

3. Restricted Cash Equivalents

The Company has $750 of available credit in conjunction with a Credit Card Services sub feature within the Companys revolving line of credit with Wells Fargo Bank. At December 31, 2008, the Credit Card Services Agreement required
the Company to maintain a restricted cash balance of $500 with the bank. At December 31, 2009, the Company was no longer required to maintain a restricted cash balance.

On February 21, 2007, the Company entered into a revolving credit facility with
Silicon Valley Bank (SVB), under which it could borrow up to $5 million. The credit facility was collateralized by all of its assets with the exception of the Companys intellectual property.

In July 2008, the Company entered into an amendment to the credit facility which added a term loan whereby the Company could borrow up to
$3.0 million and which extended the repayment date for borrowings under the revolving line of credit to July, 2010. The Company repaid all outstanding amounts under the credit facility with SVB in September 2009.

In October 2009, the Company terminated its revolving line of credit facility with SVB and entered into a revolving credit facility with

The weighted-average grant-date fair value of stock
granted during 2009, 2008 and 2007 where the exercise price on the date of grant was equal to the stock price on that date, was $3.56, $2.57, and $2.59, respectively.

Expense related to non-employee stock options is being amortized over the vesting period, which is generally four years. During the years ended December 31, 2009, 2008, and 2007, $33, $(8), and $42,
respectively, was recorded as compensation expense for the change in the fair value of unvested non-employee option grants. During the years ended December 31, 2009 and 2008, the Company did not grant any options to non-employees. For the year
ended December 31, 2007, the Company granted 10,000 options to non-employees. As of December 31, 2009, 2008 and 2007, a total of 83,350, 95,000, and 187,000 non-employee stock options, respectively, were outstanding. As of
December 31, 2009, 2008 and 2007, a total of 83,350, 76,667, and 168,667, non-employee stock options, respectively, were fully vested.

During the years ended December 31, 2009 and
2008, we granted 160,000 and 525,000 shares of restricted stock, respectively. We did not grant restricted stock during the year ended December 31, 2007. Restricted stock is granted subject to restrictions as to sale or other disposition of
shares and to restrictions that require continuous employment with the Company. The restrictions generally expire in either two or four years from the date of grant. Grants with a two year expiration completely vest after two years. Grants with a
four year term vest 25% after one year, with the remainder vesting in equal monthly amounts over the remaining three years. The grant-date fair value of shares granted during the years ended December 31, 2009 and 2008, was $520 and $1,389,
respectively. The weighted-average grant-date fair value per share for restricted stock granted was based upon the closing market price of the Companys common stock on the grant dates of the awards and was $3.25 and $2.65 per share for the
years ended December 31, 2009 and 2008, respectively. As of December 31, 2009, none of the shares vested. The Company recorded stock-based compensation related to restricted stock of $772 and $432 for the years ended December 31, 2009
and 2008, respectively. As of December 31, 2009, the unrecorded stock-based compensation balance related to restricted stock awards was $694, and will be recognized over an estimated weighted average amortization period of 1.0 years.

Employee Stock Purchase Plan

Under the terms of the Companys 2006 Employee Stock Purchase Plan (the Purchase Plan), eligible employees can purchase
common stock through payroll deductions at a price equal to the lower of 85% of the fair market value of the Companys common stock at the beginning or end of the applicable offering period. In 2008, an additional 250,000 shares of common stock
were approved and in 2009, another 1,500,000 shares of common stock were approved for issuance under the Purchase Plan. During the years ended December 31, 2009, 2008, and 2007, $335, $169, and $155, respectively, was recorded as stock based
compensation expense under the Purchase Plan. During 2009, 2008, and 2007, a total of approximately 489,000, 357,000, and 180,000, shares of common stock, respectively, were purchased at an average price of $1.61, $1.39, and $2.74, respectively.

Stock Based Compensation

The Company uses the Black-Scholes option pricing model as the valuation model to calculate the fair value of stock based compensation. The model requires extensive use of financial estimates and
accounting judgment, including estimates of the expected period of time employees will retain their vested stock options before exercising them, the expected volatility of the Companys common stock over the expected term, and the number of
shares that are expected to be forfeited before they are vested. Application of alternative assumptions could produce significantly different estimates of the fair value of the stock-based compensation and as a result, significantly different
results recognized in the consolidated statements of operations.

The weighted average of the assumptions used to estimate the
fair value of stock options granted using the Black-Scholes valuation method was as follows:



|                             |  |      |   |  |      |   |  |      |

During 2008, the Housing Assistance Act of 2008 was enacted. This act contains a provision that allows
taxpayers to claim a partial refund of its research and development credit and alternative minimum tax credit carryforwards (accelerated credits) in lieu of claiming certain tax depreciation deductions. The Company has elected to claim
the accelerated credit claim and as of December 31, 2009 and estimates a total refundable credit of approximately $48.

Significant components of the Companys deferred tax assets and (liabilities) are as follows at December 31:

Based upon the Companys history of continuing operating losses, realization of its
deferred tax assets does not appear more likely than not. The Company recorded a valuation allowance of $48.0 million. In determining the net asset subject to a valuation allowance, the Company recorded a deferred tax liability related to its
indefinite-lived other intangible assets that is not expected to reverse in the foreseeable future resulting in a net deferred tax liability of approximately $1.0 million after application of the valuation allowance.

The valuation allowance increased by $425, $4,973, and $5,517, in 2009, 2008 and 2007, respectively.

At December 31, 2009, the Company had net operating loss carryforwards for federal and state income tax purposes of approximately
$105,366 and $58,436, respectively. The federal net operating loss carryforward will begin expiring in 2015. The state net operating loss began expiring in 2007. In addition, the Company had research and development and other tax credits for federal
and state income tax purposes of approximately $3,218, and $3,077, respectively, which begin to expire in 2018. The state research and development credits do not expire for California purposes. In addition, the Company has approximately $110 of
California Manufacturers Investment Credits, which begin to expire in 2010.

The table of deferred tax assets and
liabilities shown above does not include certain deferred tax assets at December 31, 2009 and 2008 that arose directly from (or the use of which was postponed by) tax deductions related to equity compensation in excess of compensation
recognized for financial reporting. Those deferred tax assets include federal and state net operating losses. Equity will be increased by $91 if and when such deferred tax assets are ultimately realized. The Company uses SFAS 109 ordering for
purposes of determining when excess tax benefits have been realized.

Utilization of the NOL and R&D credit carryforwards
may be subject to a substantial annual limitation due to an ownership change (as defined) that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the
Code), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards, and other tax attributes, that can be utilized annually to offset future taxable income and tax,
respectively. In general, an ownership change as defined by Section 382 of the Code results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of
the outstanding stock of a company by certain stockholders or public groups. Since the Companys formation, the Company has raised capital through the issuance of capital stock on several occasions which, combined with the purchasing
stockholders subsequent disposition of those shares, may have resulted in such an ownership change, or could result in an ownership change in the future upon subsequent disposition.

The Company has not completed a study to assess whether an ownership change has occurred or whether there have been multiple ownership
changes since the Companys formation due to the complexity and cost associated with such a study. If the Company has experienced an ownership change at any time since its formation, utilization of the NOL, R&D credit carryforwards, and
other tax attributes, would be subject to an annual limitation under Section 382 of the Code. In general, the annual limitation, which is determined by first multiplying the value of the Companys stock at the time of the ownership change
by the applicable long-term, tax-exempt rate, could further be subject to additional adjustments, as required. Any limitation may result in the expiration of a portion of the NOL or R&D credit carryforwards before utilization. Further, until a
study is completed and any limitation is known, no amounts are being considered as an uncertain tax position or disclosed as an unrecognized tax benefit under FIN 48. Due to the existence of the valuation allowance, future changes in the
Companys unrecognized tax benefits will not impact its effective tax rate. Any carryforwards that will expire prior to utilization as a result of a limitation under Section 382 will be removed from deferred tax assets with a corresponding
reduction of the valuation allowance.

The results of operations for the years ended December 31, 2009, 2008 and 2007
include the net losses of the Companys wholly-owned German subsidiary of $17, $11, and $14, respectively.

The Company has not recognized any additional liability for unrecognized tax benefits.
The Company expects any resolution of unrecognized tax benefits, if created, would occur while the full valuation allowance of deferred tax assets is maintained; therefore, the Company does not expect to have any unrecognized tax benefits that, if
recognized, would affect the effective tax rate.

The Company is subject to taxation in the U.S. and various states. The
Companys tax years for 2006, 2007, and 2008 are subject to examination by the taxing authorities. With few exceptions, the Company is no longer subject to U.S. federal, state, local or foreign examinations by taxing authorities for years
before 2006.

13. Employee Benefit Plan

The Company provides a 401(k) Plan for all employees 21 years of age or older. Under the 401(k) Plan, eligible employees voluntarily contribute to the Plan up to 100% of their salary through payroll
deductions, subject to statutory limitations. Employer contributions may be made by the Company at its discretion based upon matching employee contributions, within limits, and profit sharing provided for in the Plan. No employer contributions were
made in 2009, 2008, or 2007.

14. Legal Matters

The Company is involved in various claims and legal proceedings of a nature considered normal to its business, including product liability, intellectual property, employment and other matters. The Company
is involved in litigation with Cook Medical Incorporated (Cook), alleging that the Company infringed two of Cooks patents, one of which was granted in 1991 and the other in 1998. The lawsuit was filed by Cook in the United States
District Court, Southern District of Indiana, on October 8, 2009. In December 2009, the United States Patent Office (PTO) granted the Companys request for a reexamination of the two patents asserted by Cook in the lawsuit. In
January 2010, the United States District Court ordered that the lawsuit be stayed pending the outcome of the patent reexaminations. In February 2010, the PTO completed its reexamination process and concluded that one of the two patents in question
was invalid, while the validity of the second was upheld. As of March 5, 2010, the legal proceedings remain stayed.

The
Company accrues for contingent liabilities when it is probable that a liability has been incurred and the amount can be reasonably estimated. These accruals are adjusted periodically as assessments change or additional information becomes available.
At December 31, 2009, the Company had not accrued for any contingent liabilities. While it is possible that the Company may incur costs in connection with this matter, it is unable to provide a reasonable estimate of the range of any such costs
that may be incurred.

Management is of the opinion that the outcome of these matters will not have a material adverse effect
on the Companys financial position, results of operations, or cash flow. However, as these matters are ongoing, there is no assurance that these matters will be resolved favorably by the Company or will not result in a material liability.
