Revenue Recognition
  §
    
    Persuasive Evidence of an Arrangement. Persuasive evidence of an
arrangement for sales of Sensei systems is determined by a sales contract signed and
dated by both the customer and the Company, including approved terms and conditions.
Evidence of an arrangement for the sale of disposable products is determined through
an approved purchase order from the customer.§
    
    Delivery.
 §
    
    Multiple-element Arrangements. Typically, all products and services sold
to customers are itemized and priced separately. In arrangements that include
multiple elements, the Company allocates revenue based on vendor-specific
objective evidence of fair value (VSOE) and defers revenue for undelivered
items. VSOE for each element is based on the price for which the undelivered
item is sold separately, determined based on historical evidence of
stand-alone sales of these elements, price lists or stated renewal rates for
the element. When the Company cannot reasonably determine the price of an
element, the Company cannot establish VSOE and the entire arrangement fee is
deferred until all elements are delivered. If the Company cannot establish
VSOE for an element of the arrangement and the only undelivered element is
post-contract customer support (PCS), the arrangement fee is recognized
ratably over the term of the PCS.§
    
    Systems.Typically, ownership of the Sensei systems passes to customers
upon shipment. The Company is currently the only party capable of installing
the Sensei system and training doctors as to its proper use. Sales contracts
for systems typically include installation and training. These services are
not as yet offered on a stand-alone basis. As the Company is not currently
able to reliably estimate the fair value of these services based on VSOE, all
system revenues are currently deferred until training and installation are
completed.§
    
    Disposable Products.Ownership of Artisan control catheters and other
disposable products typically passes to customers upon shipment, at which time
delivery is deemed to be complete.
 §
    
    Sales Price Fixed and Determinable. Sales prices are documented in the
executed sales contract or purchase order received prior to shipment. The Companys
standard terms do not allow for contingencies, such as trial or evaluation periods,
refundable orders, payments contingent upon the customer obtaining financing or other
contingencies which would impact the customers obligation. In situations where
contingencies such as those identified are included, all related revenue is deferred
until the contingency is resolved.§
    
    Collectibility. The Companys sales contracts generally do not allow the
customer the right of cancellation, refund or return, except as provided under the
Companys standard warranty. If such rights were allowed, all related revenues would
be deferred until such rights expired.
 Allowance for Doubtful Accounts

ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 The following discussion should be read in conjunction with the condensed consolidated
financial statements and notes thereto appearing elsewhere in this Quarterly Report on Form 10-Q .
 Except for the historical information contained herein, the matters discussed in this
Managements Discussion and Analysis of Financial Condition and Results of Operations, are
forward-looking statements that involve risks and uncertainties. In some cases, these statements
may be identified by terminology such as may, will, should, expects, could, intends,
might, plans, anticipates, believes, estimates, predicts, potential, or continue,
or the negative of such terms and other comparable terminology. These statements involve known and
unknown risks and uncertainties that may cause our results, levels of activity, performance or
achievements to be materially different from those expressed or implied by the forward-looking
statements. Factors that may cause or contribute to such differences include, among others, those
discussed in this report in Part II, Item 1A Risk Factors. Except as may be required by law, we
undertake no obligation to update any forward-looking statement to reflect events after the date of
this report.

Critical Accounting Policies, Estimates and Judgments
   Revenue Recognition
  §
    
    Persuasive Evidence of an Arrangement. Persuasive evidence of an
arrangement for sales of Sensei systems is determined by a sales contract signed and
dated by both the customer and us, including approved terms and conditions. Evidence
of an arrangement for the sale of disposable products is determined through an
approved purchase order from the customer.§
    
    Delivery.
 §
    
    Multiple-element Arrangements. Typically, all products and services sold
to customers are itemized and priced separately. In arrangements that include
multiple elements, we allocate revenue based on vendor-specific objective
evidence of fair value, or VSOE, and defer revenue for undelivered items. VSOE
for each element is based on the price for which the undelivered item is sold
separately, determined based on historical evidence of stand-alone sales of
these elements, price lists or stated renewal rates for the element. When we
are not able to reasonably determine the price of an element, we cannot
establish VSOE and we defer the entire arrangement fee until all elements are
delivered. If we cannot establish VSOE for an element of the arrangement and
the only undelivered element is post-contract customer support, or PCS, the
arrangement fee is recognized ratably over the term of the PCS.§
    
    Systems.Typically, ownership of our Sensei systems passes to our customers
upon shipment. We are currently the only party capable of installing our
Sensei system and training doctors as to its proper use. Sales contracts for
our systems typically include installation and training. These services are
not as yet offered on a stand-alone basis. As we are not currently able to
reliably estimate the fair value of these services based on VSOE, we currently
defer all system revenues until training and installation are completed.

##### Table of Contents



§
    
    Disposable Products.Ownership of our Artisan catheters and other
disposable products typically passes to our customers upon shipment, at which
time delivery is deemed to be complete.
 §
    
    Sales Price Fixed and Determinable. Sales prices are documented in the
executed sales contract or purchase order received prior to shipment. Our standard
terms do not allow for contingencies, such as trial or evaluation periods, refundable
orders, payments contingent upon the customer obtaining financing or other
contingencies which would impact the customers obligation. In situations where
contingencies such as those identified are included, we defer all related revenue
until the contingency is resolved.§
    
    Collectibility. Our sales contracts generally do not allow the customer
the right of cancellation, refund or return, except as provided under our standard
warranty. If such rights were allowed, we would defer all related revenues until such
rights expired.

ITEM 1A. RISK FACTORS
 Any investment in our stock involves a high degree of risk. You should consider carefully the risks
and uncertainties described below before you decide whether to purchase our common stock. The risks
and uncertainties described below are not the only ones facing us. Additional risks and
uncertainties, not presently known to us, or that we currently see as immaterial, may also harm our
business. If any of the following risks actually occurs or any of the additional risks not
presently known to us occur, our business could be materially harmed and our financial condition
and results of operations could be materially and adversely affected.
 Risks Related to Our Business
 We are a company with a limited history of operations, which makes our future operating results
difficult to predict.
  We have limited sales, marketing and distribution experience and capabilities, which could impair
our ability to achieve profitability.
  
    
    our ability to recruit, train and retain adequate numbers of qualified sales and
marketing personnel;
    
    the ability of sales personnel to obtain access to or persuade adequate numbers of
hospitals to purchase our products or physicians to use our products;
    
    costs associated with hiring, maintaining and expanding an independent sales and
marketing organization; and
    
    government scrutiny and labeling restrictions with respect to promotional activities in
the healthcare industry.

We have limited experience in manufacturing and assembling our products and may encounter problems
at our manufacturing facilities or otherwise experience manufacturing delays that could result in
lost revenue.
   Our reliance on third-party manufacturers and on suppliers, and in one case, a single-source
supplier, could harm our ability to meet demand for our products in a timely manner or within
budget, leading to possible losses of revenue.
   
    
    suppliers may fail to comply with regulatory requirements or make errors in
manufacturing components that could negatively affect the efficacy or safety of our
products or cause delays in or prevent shipments of our products;
    
    we may not be able to respond to unanticipated changes and increases in customer
orders;
    
    we may be subject to price fluctuations due to a lack of long-term supply arrangements
for key components with our suppliers;

##### Table of Contents




    
    we may lose access to critical services and components, resulting in an interruption in
the manufacture, assembly and shipment of our systems and other products;
    
    our suppliers manufacture products for a range of customers, and fluctuations in demand
for products these suppliers manufacture for others may affect their ability to deliver
components to us in a timely manner;
    
    our suppliers may wish to discontinue supplying goods or services to us beyond the
development phase for risk management reasons, such as intellectual property reasons or
medical products liability reasons;
    
    we may not be able to find new or alternative components for our use or reconfigure our
system and manufacturing processes in a timely manner if the components necessary for our
system become unavailable; and
    
    our suppliers may encounter financial hardships unrelated to our demand for components,
which could inhibit their ability to fulfill our orders and meet our requirements.
   If we fail to maintain necessary FDA clearances and CE marks for our medical device products, or if
future clearances are delayed, we will be unable to commercially distribute and market our
products.

procedures, we may not be commercially successful.
   We expect to derive substantially all of our revenues from sales of our Sensei system and Artisan
catheters. If hospitals do not purchase our system, we may not generate sufficient revenues to
continue our operations.
  We have incurred substantial losses since inception and anticipate that we will incur continued
losses for the foreseeable future.
