Introduction 
3.1 
Background and Rationale 
Surgical site wound closure plays a vital role in post-operative success. This effect is magnified with 
commonly performed elective procedures such as knee arthroplasty[1].  Sutures and staples are most 
commonly used based on surgeon preference and wound location. Staples are frequently used due to their 
deployment speed advantage over sutures. It has been suggested that the ideal method of wound/incision 
closure should be fast and non-traumatic, be associated with a low incidence of dehiscence and infection, 
and should yield acceptable cosmetic results; and while sutures and staples are presently the most common 
method of surgical closure, they do not demonstrate many of these properties [1,2]. Therefore, developing 
new methods to reduce overall treatment time while producing comparable or potentially improved cosmetic 
scar results and maintaining low complication rates has obvious benefits. 
ZipLine Medical, Inc. has developed a novel, non-invasive skin closure device called “Zip Surgical Skin 
Closure” to replace sutures, staples and glue for closure of the skin layer for surgical incisions or laceration 
repair.  The device is FDA Class I, 510(k) Exempt and began commercial use in the USA in April 2013.  
The device is designed to provide closure speed superior to sutures, while resulting in a suture-like cosmetic 
outcome.  Both pre-clinical feasibility study data and feedback from over 2000 human cases during the 
device’s commercial use in the USA suggest that these design intentions are correct.  This study will test 
these assertions in a controlled clinical setting, with the goal of providing results with statistical significance.     
We anticipate this clinical study to be completed within 12 months from site initiation/training to site 
closure. 
3.2 
Summary of Findings from Previous Studies 
3.2.1 
Pre-clinical Studies  
Preclinical feasibility testing of the ZipLine technology using a chronic porcine model was conducted in 
2010.  Surgical incisions were closed either with the ZipLine technology, or absorbable subcuticular 
sutures.  Devices were removed at two weeks post-operatively, and resulting scars were evaluated at 6-
weeks by a blinded panel of four board-certified plastic surgeons.  Results revealed excellent cosmesis when 
compared to subcuticular suture controls. 
Below is an example of comparative outcomes at 2 weeks post-op: 
ZipLine Closure 
Subcuticular Suture Closure 
 
The Cosmetic Visual Analog Scale (CVAS) and ordinal Wound Evaluation Scale (WES) were used to 
evaluate photographs of each scar from the test subjects.  Evaluators were blinded to the type of closure 
method used for each wound.

These results suggest that incisions and excisions closed using ZipLine technology can result in at least 
equivalent cosmesis when compared to suture closure.  
 
Histology 
Histological analysis was performed on sample scars from both test and control groups. 
Surgical Incision Closure 
Subcuticular Suture Closure

Skin Excision Closure  
Subcuticular Suture Closure 
ZipLine Closure 
  
H&E staining was performed on representative cross-sections of incisions closed with traditional suture 
techniques vs. the ZipLine device.  The width and depth of the resulting scars as well as the degree of local 
inflammatory response were evaluated by a pathologist blinded to the closure method.  The degrees of 
scarring and inflammation were deemed to be qualitatively equivalent between the two groups. 
This was an internal feasibility study and the results have not been published. 
  
3.2.2 
Clinical Studies 
Mt. Sinai School of Medicine- 
A randomized, controlled, prospective post-market study was recently completed at Mt. Sinai School of 
Medicine’s Division of Mohs, Reconstructive, and Cosmetic Surgery.  The study compared suture control to 
an earlier variant of the Zip Surgical Skin Closure device for skin cancer excision.  The manuscript has been 
completed and submitted to a peer-reviewed journal for publication. 
Preliminary clinical study results from this study were presented at the 16th Annual Mount Sinai Winter 
Symposium on Advances in Medical and Surgical Dermatology which took place Dec. 6-8, 2013 in New 
York. 
Hooman Khorasani, M.D., Chief of the Division of Mohs, Reconstructive, and Cosmetic Surgery at Mount 
Sinai School of Medicine, and principal investigator for the study presented the preliminary results to an 
audience of over 400 dermatological surgeons.  He is deeply involved in minimal scar wound repair research 
and has done extensive research in this area of scar-less wound healing. He is currently conducting two 
clinical trials addressing improved scarring after surgery. 

 
 
 
“In the study, the ZipLine device produced similar cosmetic outcomes to a traditional suture closure while 
significantly reducing the treatment time, which can in turn reduce the overall cost of the procedure.  In 
addition, since with the ZipLine there are no sutures to remove, this limited the need for immediate patient 
return, which can benefit both the patient and clinic.  The patient can instead return later when the wound is 
more healed,” said Dr. Khorasani.  The preliminary data suggested a 57% reduction in wound closure 
procedure time when using the ZipLine device instead of sutures.   
UC San Diego CIED (Pacemaker) Study – 
A blinded, controlled and randomized study is currently underway at UC San Diego. Most cases have 
already been completed with promising results. A total of 40 patients underwent pacemaker or defibrillator 
insertions, and skin closure was randomly assigned to either subcuticular sutures or the Zip Surgical Skin 
Closure device. Primary endpoints for the study are closure time and cosmesis. 
The Zip Surgical Skin Closure Device is an FDA Class I, 510(k) Exempt device, and no clinical studies 
were required for regulatory clearance.  The aforementioned clinical studies are post-market studies aimed at 
providing statistically significant performance data regarding the Zip device.

Device Description 
4.1 
 Device Overview 
ZipLine Medical, Inc. has developed a novel, non-invasive skin closure device called “Zip Surgical Skin 
Closure” to replace sutures, staples and glue for closure of the skin layer for surgical incisions or laceration 
repair.  The device is designed to provide closure speed superior to sutures, while resulting in a suture-like 
cosmetic outcome.  Both pre-clinical feasibility study data and feedback from over 2000 human cases during 
the device’s commercial use in the USA suggest that these design intentions are correct.  This study will test 
these assertions in a controlled clinical setting, with the goal of providing results with statistical significance.     
The Zip device is a single use, sterile medical device. 
 
 
Figure 1. Zip Surgical Skin Closure Device 
 
The Zip Surgical Skin Closure Device is applied to clean, dry skin after deeper tension-relieving (i.e., 
dermal or subcutaneous) sutures have been applied. 
The device adheres to the skin adjacent to an incision by use of pressure-sensitive skin adhesives.  A 
combination of acrylic and hydrocolloid adhesives are used to provide a skin-friendly environment while 
providing the necessary tack to maintain skin adhesion during the recommended wear time of the device (7-
14 days). 

 
 
Figure 2. Adjusting Incision Closure Tension 
 
The device remains on the skin for the recommended 7-14 days.  During this period, patients may shower 
(but not soak in a tub or pool) with the device on.  The device is removed by lifting the edge of the device 
and gently peeling along the incision, taking care not to apply stress to the incision.  If there is a risk of skin 
stripping, an adhesive removal agent may be used during removal. 
 
 
Figure 3. Key Components of the Zip Surgical Skin Closure Device 
In addition to the pressure-sensitive adhesives, the device’s closure and force distribution components are 
made up of polyurethane monofilm, polyethylene tape, polyester and nylon.

After application, the surgeon approximates the incision edges and tensions the wound by adjusting the 
ratcheting straps located along the device.  Once the desired tension is achieved, the excess strap ends are 
trimmed with scissors, and a conventional absorptive dressing may be applied.   
4.2 
Regulatory Status 
The Zip Surgical Skin Closure is a FDA Class I, 510(k) Exempt device. 
In 2010, ZipLine Medical, Inc. submitted a “513(g)” request for product classification to the U.S. Food and 
Drug Administration (FDA).  In July 2010, ZipLine Medical received a letter from the FDA indicating that 
FDA reviewers “believe the ZipLine 1 System falls within Title 21 of the Code of Federal Regulations (CFR) 
880.5240, Medical adhesive tape and adhesive bandage (Product Code- KGX).  A Medical adhesive tape 
and adhesive bandage is a Class I type device, exempt from the premarket notification [510(k)] 
requirements of the Act, subject to the limitations of the exemption found in 21 CRF 880.9.” 
Quality System Regulations:  The Zip Surgical Skin Closure Devices have been developed and are 
manufactured in full compliance with FDA Title 21 CFR Part 820 Quality System Regulations, including 
design controls, document controls, purchasing controls, identification and traceability, production and 
process controls, acceptance activities, nonconforming product, corrective and preventive action, labeling 
and package control, handling, storage, distribution and installation, record keeping, servicing, and statistical 
techniques. 
Origin of Manufacture:  The Zip® brand Surgical Skin Closure Devices are manufactured in the USA. 
Company Registration:  ZipLine Medical, Inc. is registered with the FDA in compliance with Title 21 
Code of Federal Regulations (CFR) Part 807, Subparts A-D. 
4.3 
Indication For Use 
The Zip Surgical Skin Closure Device is indicated for use during and after skin incision procedures to 
approximate skin and hold together the skin edges until healing can take place. 
4.4 
Device Labeling 
The Zip Surgical Skin Closure Devices are labeled in full compliance with FDA Title 21 CFR Part 820 
Quality System Regulations.  Each device label includes the device name, part number, lot number and 
expiration (use by) date.  The devices are provided sterile, each in a sealed pouch designed for aseptic 
handoff into a sterile field.  The devices are provided in boxes of 10 individually packaged devices, and a 
copy of the device Instructions For Use (IFU) accompanies each box of 10 devices.    
4.5 
Commercial Status and Clinical Experience 
The Zip device has been commercially available since April 2013, with over 2000 clinical cases conducted 
in the USA, and approximately 60% of these cases being orthopedic procedures.  Feedback from these cases 
includes the following:  
• 
Orthopedic surgeons generally close in several layers, including a deep dermal layer. 
• 
Devices are typically removed at 10-14 days.   
• 
Orthopedic surgeons have indicated that they are impressed with the ease of application 
at the end of a case; in some cases surgeons delegated skin closure with the Zip to an 
assistant, such as a Physician’s Assistant in the sterile field.  They also felt that the 
outcomes were excellent at the time of removal. 
• 
Orthopedic surgeons liked the ability to cut the device to match the incision size and to 
combine devices for longer incisions.

Study Objective 
The primary objective of this post-market study is to evaluate scar appearance / cosmesis 
associated with the use of the Zip Surgical Skin Closure versus conventional staples when utilized 
for surgical wound closure after bilateral knee arthroplasty (unicompartmental or total).  For safety 
analysis, the rate of adverse events up to 8 weeks post-surgery will be compared between the 
ZipLine Surgical Skin Closure and standard staples. 
5.1 
Sample Size 
A total of up to 25 subjects (targeted min. n=22) requiring bilateral knee arthroplasty 
(unicompartmental or total) will be enrolled.  There is anticipated patient fall out (screen 
failures) post procedure due to surgeon not knowing exactly which procedure is required 
(total or unicompartmental) until time of surgery. Subjects who are initially enrolled in the 
study and surgery results in a total knee on one side and a unicompartmental on the other 
side will be exited from the study and not included in the final analysis. Each subject will 
serve as their own control since one knee closure will be with staples, and the other knee 
closure with Zip device.  The order of patients will be randomized to receive Zip device 
on one knee and steel staples on the opposing knee.

8.4 
Study Procedures 
 
8.4.1 
Pre-Procedure 
Prior to the subject’s scheduled procedure, obtain informed consent, a medical history, pain assessment, 
ROM and record the subject’s demographic (age, race, sex and date of birth) and baseline information 
(height, weight). Patient’s medical records may be screened prior to obtaining consent to assess eligibility 
for the study.  
(Please reference Figure 4 – Schematic of Study Design) 
 
8.4.2 
Randomization – Wound Closure Device Placement 
All subjects will be screened for inclusion/exclusion criteria by study site personnel.   
Once the screening and consent process is completed, subjects will be randomized to receive the Zip device 
(Treatment Group) on either the right or left knee by opening one of the sealed envelopes containing a 
randomization card.  The subject will receive the staples (Control Group) on the opposing knee. The subject 
is considered enrolled into the study upon randomization and the subject disposition will be accounted for in 
study reports.    
8.4.3 
Procedure 
For consented subjects that meet the eligibility criteria, record the relevant data regarding their procedure.  
Record the following procedure information: 
• 
Treatment and control sides 
• 
Length of incisions 
• 
Note: Subjects who require a total knee on one side and a unicompartmental on the other side will not 
be included in the final analysis and should be exited from the study. 
8.4.4 
Wound Closure Procedure / Protocol 
The Zip device placement will be carried out following a standard protocol as described in the Instructions 
for Use (IFU) 
8.4.5 
Data to be collected at time of procedure and/or prior to discharge: 
• 
Closure Method Satisfaction (Surgeon Rating) 

 
• 
Pain (Subject Rating) - A 11 point Numerical Rating Scale rating pain from No Pain (0) to Worst Pain 
Imaginable (10) will be used to measure general pre and post-operative pain and specific incisional pain. 
• 
Any complications/adverse events 
• 
High resolution digital photographs of any preexisting scar or unusual skin appearance at the incision 
site and immediately after incision closure (optional) 
8.4.6 
Data to be collected at follow up visits 
While performing the 2 week follow up visit, record the following information:  
• 
Cosmetic Outcome (Surgeon Rating)

Scar Satisfaction - A  5 point Likert Scale ranging from Very Satisfied to Very Dissatisfied  
o 
Scar Assessment - A 10 point Visual Analog Scale rating scar cosmesis from 0=Best 
Expected Scar  to 10=Worst Scar 
o 
Wound Evaluation Scale (WES) – The surgeon will conduct a follow up evaluation of the 
wound using the WES assessment. The WES evaluates six clinical variables including 
incision edges, contour irregularity, width, edge inversion, inflammation and overall 
cosmesis. 
o 
Cosmetic Visual Analogue Scale (CVAS) – High definition photos will be taken of the 
incision/scar area at the final follow-up visit. Photos will be collected and evaluated using a 
VAS Scar Score by an objective independent panel (not affiliated with the study site) of up to 
5 plastic surgeons. 
8.5 
Follow-up 
The subject should be queried before discharge regarding any discomfort experienced after Zip device and 
staple use.  After removal of both the Zip device and staples the status of the wounds should be assessed.  
Any Adverse Events should be noted. These data will be captured on the Case Report Forms.  High 
resolution digital photographs should be taken after closure device removal (day 14) and at final 6 or 8 week 
follow-up visit.  A user survey will be provided and will be required to be filled out as part of the follow-up.  

 
Scar / cosmetic appearance will be evaluated on a visual analogue scales (CVAS). Physician and patient 
satisfaction with the closure techniques and the scar appearances will be evaluated. 
8.6 
Study Exit 
Once the subject has completed the final follow-up visit or has withdrawn early, they should be exited from 
the study.  The date of exit and subject status should be recorded on the Case Report Form.

Statistical Considerations 
9.1 
 Analysis Populations and Data Handling Conventions   
9.1.1 
Effectiveness Intent-to-Treat (ITT) Population 
All subjects will be included in effectiveness ITT analyses according to the randomized order of patients  
for treatment assignments, including the dermal closure procedure, regardless of protocol deviations.   
9.1.2 
Effectiveness Per Protocol Population 
The effectiveness per protocol population includes all subjects completing Zip Surgical Skin Closure and 
standard dermal closure (Staple) treatments per protocol.  The analysis will be performed according to the 
actual treatments received, including the dermal closure procedure. 
9.1.3 
Safety 
All subjects who receive any portion of the Zip Surgical Skin Closure treatment or control (staple) treatment 
will be included in safety analysis and analyzed by actual treatment received. 
9.1.4 
Missing Data 
Missing or loss data will not be included in the analysis. 
9.2 
Statistical Analysis Plan  
9.2.1 
General Summary  
CVAS summary statistical results will include, averages standard deviation, range, and Coefficient of 
Variation (CVs) will be reported for both the control and treatment.  Results will include significance testing 
(t test) with calculated p value(s).  Graphic representation of data with distribution analysis of CVAS results 
will also be presented and summarize.  All variables of interest including subject demographics, baseline 
characteristics, effectiveness and safety endpoints will be summarized. 
9.2.2 
Effectiveness  
11.2.2.1. Primary Effectiveness Analyses 
There is one primary endpoint for the study, i.e. Cosmetic Visual Analogue Scale (CVAS) for incision 
appearance at the final (6 to 8 week) follow-up evaluation for gathering CVAS scores.  The purpose is to 
reveal superior cosmesis results of Zip device in comparison to standard staple closure. The sample size 
determined, per Section 7, for this study is up to 25 patients. 
 
CVAS 
The hypothesis for cosmesis is that use of the Zip Surgical Skin Closure device will result in CVAS results 
that are significantly superior to standard staples administered.  A 1-sided paired “t” test will be performed 
to reject the H0 with >95% confidence. Alpha Error for the 1-sided test = 0.025.   
The assumption (hypothesis) for CVAS is:    
H0:  Zipline CVAS scores will not be superior to CVAS scores for staples. 
HA: Zipline CVAS scores will be superior to CVAS scores for staples. 

 
Since CVAS scores are measured on a 0 – 10 Likert scale for quality of closure, a distribution analysis will 
also be performed with summary statistics to show that the incisions closed with the Zip devices result in a 
cosmetically superior scar as compared to the incisions closed with staples. 
 
11.2.2.2  Secondary “Effectiveness” Endpoints Analyses 
Secondary effectiveness endpoints include surgeon and patient closure method satisfaction, scar appearance 
satisfaction and patient pain and comfort surveys. All results will be summarized by treatment. 
9.2.3 
Safety 
Cumulative adverse events from time of closure to final visit (6 to 8 weeks post op) will be collected, 
analyzed and summarized by closure treatment.   Separate tables will be constructed for (a) all reported 
adverse events, (b) adverse events reported as closure device related, and/or (d) serious adverse events.   
The primary safety analysis will be the overall comparison between Zip and staple adverse events. 
 
9.3 
Sample Size Justification 
 
Since this is a Bilateral Study, with CVAS scores (Scores:  0 – 10), a paired “t” significant test is the most 
appropriate test as there is only one variable changing with the patients, i.e., type of closure device.   A 
paired “t” test has more statistical power as well, and is more appropriate since the results will be comparing 
the treatment and control in a paired fashion. 
The targeted  minimum sample size of  n=22 subjects (paired observations) was determined assuming an 
average difference (∆) > 1.0, an hypothesized standard deviation of ~1.5, with the Power of Test set at 
90%.  Alpha Error for the test of differences = 0.025. 
 
10 Data Management – Data Collection and Processing 
Conventional paper-based CRFs will be used.  Investigators are responsible for the accurate completion and 
timely submission of the data collected during the study.  All data from the study will be entered into CRFs.  
Any data issues are to be promptly addressed with the investigator by the sponsor or designee.  Investigator 
and staff training will take place prior to subject enrollment to ensure that complete, accurate and timely data 
are submitted, that protocol requirements are followed and that complications, adverse events and adverse 
device effects are correctly reported and investigated, as appropriate.  Investigators are to maintain all source 
documents as required by the protocol, including laboratory results, supporting medical records, and signed 
Informed Consent forms.  The source documents will be used during the regular monitoring visits to verify 
information from the database against data contained on the completed CRFs.  
The Principal Investigator must maintain detailed records on all subjects who sign the Informed Consent and 
begin the pre-procedure evaluation.  Data for enrolled subjects will be entered into CRFs provided by the 
Sponsor.  All data should be entered completely, promptly and legibly.  For source documents, corrections 
should be made in a manner that does not obscure or eliminate the original error, by striking through the 
original data with one line, and initialing and dating the change, along with the reason for the change (if not 
obvious).   
Study Exit CRFs are completed for all enrolled subjects, regardless if they did or did not complete the study 
(e.g., subject discontinuation, study termination). 
 
 

 
11 Monitoring Procedures 
11.1 Monitoring  
Monitoring visits to the clinical sites will be made periodically during the study, to ensure that all aspects of 
the current, approved protocol/amendment(s) are followed. Original source documents will be reviewed for 
verification of data in the case report forms. The Investigator/institution guarantees direct access to original 
source documents by ZipLine Medical Inc. personnel and their designees.  
It is important that the Investigator and relevant study personnel are available during the monitoring visits 
and that sufficient time is devoted to the process. 
Phone contacts and site visits will be conducted to ensure that the protocol is being followed and that any 
protocol deviations are properly documented.  Clinical monitoring will include a verification that Informed 
Consent was properly obtained for all enrolled study participants, a review of clinical records for accuracy 
and completeness, resolution of missing or inconsistent results and a review of source documents.  The 
clinical monitor will verify that the Case Report Forms (CRFs) are in agreement with the source 
documentation and other records.  The investigator will make available to the clinical monitor for review all 
Informed Consent documents, access to completed CRFs, source documentation, original laboratory data 
and other relevant records for all enrolled subjects at the site.  It is important that the investigator and other 
relevant site personnel are available for consultation with the clinical monitors during the monitoring visits 
and that sufficient time is devoted at the site to the monitoring process. 
Additionally, telephone and/or e-mail contact will be conducted on a regular basis with the investigator and 
the site staff to ensure that the protocol is being followed and to address any issues that may occur during the 
course of the study. 
If a deficiency is noted during an on-site visit (or at any other time during the course of the study), the 
clinical monitor is required to discuss the situation with the investigator and the Sponsor (if required) to 
secure compliance. Any protocol deviations will be reported to the IRB within the required timelines. 
 
 
12 Quality Control and Quality Assurance 
12.1 Site Training 
To ensure accurate, complete, and reliable data, the Sponsor or its representatives will provide instructional 
material to the study sites, as appropriate;  
• 
Instruct the Investigators and study personnel on the protocol, the completion of the CRFs, 
and study procedures 
• 
Communicate regularly with site personnel via mail, email, telephone, and/or fax 
• 
Make periodic visits to the study site. 
During those visits, the Sponsor or its representatives will monitor the subject data recorded in the paper 
CRFs against source documents at the study site. 
   
12.2 Audits and Inspections 
The Principal Investigator for the site will also allow representatives of the governing IRB to inspect all 
study records, CRFs, and corresponding portions of the subject’s office and/or hospital medical records at 
regular intervals throughout the study.  These inspections are for the purpose of verifying adherence to the 
protocol, and completeness and exactness of the data being transcribed onto the CRF. 

 
The Principal Investigator for the site will inform the Sponsor or the Sponsor’s designee in advance if they 
are to be audited or inspected by any regulatory agencies.  The Sponsor or the Sponsor’s designee will also 
inform the site if they are made aware of a pending audit or inspection by a regulatory agency. 
 
 
13 Adverse Events  
13.1 General  
 
All adverse events (AE) and serious adverse events (SAE) will be monitored from the time of treatment 
through 3 months.  
An AE is defined as any undesirable clinical occurrence in a subject whether or not it is considered to be 
device related. In addition, the definition of AE applies to any event with an onset post study procedure or to 
any underlying diseases, present at baseline, that exacerbate in severity post study procedure. Therefore, an 
underlying disease that was present at the time of enrollment is not reported as an AE, but any increase in 
the severity of the underlying disease is to be reported as an AE. This definition includes events occurring 
during the follow-up period. 
All reported AEs must be recorded. A description of the event, including the start date, resolution date, 
action taken, and the outcome should be provided, along with the Investigator’s assessment of the 
relationship between the AE, the study treatment and the study procedure. 
  
The following definitions for rating severity of adverse events will be used: 
Mild 
Awareness of signs or symptoms, but easily tolerated; are of minor irritant type; 
causing no loss of time from normal activities; symptoms would not require 
medication or a medical evaluation; signs or symptoms are transient. 
Moderate 
Interferes with the subject’s usual activity and/or requires symptomatic 
treatment. 
Severe 
Symptom(s) causing severe discomfort and significant impact of the subject’s 
usual activity and requires treatment. 
 
The following definitions will be used to rate the relationship of the adverse event to the study treatment and 
the study procedure. 
Not Related 
• 
not associated with device application 
• 
due to an underlying or concurrent illness or effect of another device or drug 
 
Possible 
• 
temporal sequence between device application and event is such that the 
relationship is not unlikely or subject’s condition or concomitant therapy 
could have caused the adverse event 
 
Probable 
• 
temporal sequence is relevant or 
• 
event abates upon device removal 
 
Definitely 
Related 
• 
temporal sequence is relevant and  
• 
event abates upon device removal or 

 
• 
reappearance of the event on repeat device re-application 
 
A serious adverse event (SAE) is defined as an event which leads to:   
• 
Death due to any cause 
• 
Life-threatening condition 
• 
Results in persistent or significant disability/incapacity 
• 
Requires in-patient hospitalization or prolonged hospitalization 
• 
Necessitates an intervention to prevent a permanent impairment of a body function or permanent damage to 
a body structure 
 
All SAE’s will be reported. 
Device-Related Adverse Event: an adverse event is considered to be device-related when, in the judgment of 
the Investigator, the clinical event has a reasonable time sequence associated with use of the device and is 
unlikely to be attributed to concurrent disease or other procedures or medications.  It is reasonable to believe 
that the device directly caused or contributed to the adverse event.  
Procedure-Related Adverse Event: an adverse event is considered to be procedure-related when, in the 
judgment of the Investigator; it is reasonable to believe that the event is associated with the assigned study 
procedure and is not specific to the device used.  Other products, surgical techniques, or medications 
required specifically for the procedure are likely to have contributed to the occurrence of the event. 
Concomitant Medication-Related Adverse Event: an adverse event is considered to be concomitant 
medication related when, in the judgment of the Investigator, it is reasonable to believe that the event is 
associated with concomitant medications used in conjunction with the device and is not otherwise specific to 
the device (e.g. bleeding associated with anticoagulation medication). 
Pre-Existing Condition-Related Adverse Event: an adverse event is considered to be related to a pre-
existing condition when, in the judgment of the Investigator, it is reasonable to believe that the event is 
associated with the subject’s pre-existing condition and is not specific to the device or procedure. Pre-
existing conditions that are aggravated or become more severe during or after the procedure should be 
evaluated on a case-by-case basis to determine if the event may be more appropriately classified as device-
related or procedure-related. 
ZipLine Medical Inc. Inc., or its designee, in cooperation with the Investigator, will assess all adverse events 
considered to be device-related for potential reportability to the FDA and other regulatory authorities as an 
Unanticipated Adverse Device Effect (UADE).  
The Investigator should follow all unresolved serious adverse events until the events are resolved, the 
subject is lost to follow-up, the subject has withdrawn consent, or the adverse event is otherwise explained. 
 
13.2 Reporting of Serious and Non-Serious Adverse Events  
13.2.1 General Reporting Requirements (Serious & Non-Serious Adverse Events) 
All serious and potentially device related and/or procedure-related adverse events must be recorded on the 
Adverse Event CRF by the Investigator (or designee).  The report should include: severity, duration, action 
taken, treatment outcome and relationship of the adverse experience to the study device, procedure, 
concomitant medications, pre-existing condition, etc. (i.e., unrelated, related or relationship unknown).   
In the case of serious adverse events, procedure and/or device observations and malfunctions, medical record 
documentation (e.g. procedure notes, operative notes, discharge summary, relevant progress notes, imaging 
or lab studies) must be provided to ZipLine Medical Inc. or its designee.  

 
The following criteria must also be adhered to by the Investigator in the case of serious adverse events: 
• 
The Adverse Event CRF must be signed by the Investigator or Co-Investigator. 
• 
It is the responsibility of the Investigator to inform their IRB/EC of serious adverse events as required by their 
IRB/EC procedures and in conformance with FDA and local regulatory requirements. 
All serious adverse events must be reported by the Investigator (or designee) to the sponsor, within 48 hours 
of learning of the adverse event via CRF. The ZipLine Medical Inc. contact information for questions is: 
Sponsor:  
ZipLine Medical, Inc. 
747 Camden Ave., Suite A,  
Campbell, CA 95008 
 
Contact: 
Christy Cowley 
Manager, Clinical Affairs 
Mobile: 408-857-2083 
13.3 Device Failures and Malfunctions 
All reported device observations, malfunctions or failures of the Zip device, ZipLine Medical Inc., are 
required to be documented in the CRF.  In the event of a suspected observation or device problem, ZipLine 
Medical, Inc. Customer Service shall be notified and the Zip device shall be returned to the Sponsor for 
analysis.  If the device has been in contact with the subject or may have been in contact with the subject’s 
bodily fluids, proper biohazard controls and labeling shall be used when handling and transporting the 
device.  Device failures and malfunctions should also be documented in the subject’s medical record. 
NOTE: Device failures or malfunctions are NOT to be reported as adverse events. However, if there is an 
adverse event that results from a device failure or malfunction, that specific event would be recorded in the 
usual way. 
 
 
14 Ethical Considerations 
14.1 Trial Conduct  
The study will be performed in accordance with US FDA Good Clinical Practice (GCP) guidelines. 
14.2 Institutional Review Board 
A copy of the protocol, proposed Informed Consent form, other written subject information and any 
proposed advertising material must be submitted to the IRB/IEC for written approval. A copy of the written 
IRB/IEC approval of the protocol and Informed Consent form must be received by ZipLine Medical Inc. 
before recruitment of subjects into the study may begin. 
The Sponsor must submit and, where necessary, obtain approval from the IRB, for all subsequent significant 
protocol amendments and significant changes to the Informed Consent form.  The Investigator should notify 
the IRB of deviations from the protocol or SAEs and UADEs occurring at the site and other SAE/UADE 
reports received from ZipLine Medical Inc. in accordance with local procedures. 
The Investigator will be responsible for obtaining annual IRB approval and renewal throughout the duration 
of the study. Copies of the Investigator’s reports and the IRB continuance of approval must be sent to 
ZipLine Medical Inc. 

 
14.3 Informed Consent Form 
The written Informed Consent documents should be prepared in the language(s) of the potential patient 
population. 
The reviewing IRB and the sponsor must first approve the Informed Consent forms that are used. The 
Informed Consent forms that are used should be in accordance with the current guidelines as outlined by the 
Good Clinical Practices (GCP) guidelines.  
Prior to participation in the clinical study, each subject must give written Informed Consent after the context 
of the study has been fully explained to the subject in language that is easily understood by the subject. The 
subject must also be given the opportunity to ask questions and have those questions answered to their 
satisfaction. 
14.4 Amending the Protocol 
An Investigator may not make protocol changes without prior approval by ZipLine Medical Inc.  All 
significant protocol changes that may affect the following must be submitted and approved by the 
Sponsor before initiating the change: 
 
• 
validity of the data or information resulting from the completion of the approved protocol; 
• 
relationship of the likely subject risk to benefit relied upon to approve the protocol; 
• 
scientific soundness of the investigational plan, or; 
• 
rights, safety, or welfare of the human subjects involved in the investigation. 
 
The change must be approved by ZipLine Medical Inc and submitted and subsequently approved by the site 
IRB. The investigative sites must send ZipLine Medical Inc. a copy of the IRB approval letter for the 
protocol amendment. 
 
ZipLine Medical Inc. may make certain administrative changes to the protocol without prior approval of the 
IRB.  ZipLine Medical Inc. will notify the investigative site and the IRB of such changes to ensure the study 
continues to be conducted consistently.  
14.5 Emergency Actions 
ZipLine Medical Inc. accepts the right of the Investigator to deviate from the protocol in an emergency when 
necessary to safeguard the life or the physical wellbeing of a study subject.  The Investigator must give 
notice of any emergency deviations and justification for the deviation to ZipLine Medical Inc. and the IRB 
as quickly as possible after the episode, in any event no later than 24 hours after the emergency to ZipLine 
Medical Inc. and 10 days to the IRB. 
14.6 Protocol Deviations 
A protocol deviation is defined as an event where the Clinical Investigator or site personnel did not conduct 
the study according to the protocol. 
Investigators shall be required to obtain prior approval from ZipLine Medical Inc. clinical study 
management and IRB before initiating deviations from the protocol, except where necessary to protect the 
life or physical wellbeing of a subject in an emergency.  Such approval shall be documented in writing and 
maintained in clinical study management and Investigator files.  Prior approval is generally not expected in 
situations where unforeseen circumstances are beyond the Investigator’s control, (e.g. subject was not 
available for scheduled follow-up office visit, blood sample lost by laboratory, etc.); however, the event is 
still considered a deviation and will be reported via the appropriate CRF. 
Deviations must be reported to ZipLine Medical Inc. regardless of whether medically justifiable, pre-
approved by ZipLine Medical Inc. or taken to protect the subject in an emergency.  Subject specific 
deviations will be reported on the Protocol Deviation case report form. Investigators will also adhere to 

 
procedures for reporting study deviations to their IRB in accordance with their specific IRB reporting 
policies and procedures. 
Regulations require that Investigators maintain accurate, complete and current records, including documents 
showing the dates of and reasons for each deviation from the protocol.   
14.7 Coverage of Expenses 
The treated subjects will not be reimbursed or compensated for participating in the study. 
14.8 Confidentiality  
Confidentiality of subjects will be maintained throughout the study.  A unique identification code will be 
assigned to each subject participating in this study.  Any data that may be published in abstracts, scientific 
journals, or presented at medical meetings will reference a unique subject code and will not reveal the 
subject’s identity.  The Sponsor and their designee will make every reasonable effort to protect the 
confidentiality of the subjects participating in the study.

Description
The Zip™ 16 Surgical Skin Closure Device is a single-use non-in-
vasive skin closure device that may be used to close up to 16cm 
of incision length. Multiple devices may be applied end-to-end as 
needed for longer incisions, and the device may be cut for shorter 
incisions. The device is applied to clean, dry skin prior to skin closure. 
The device remains on the skin during wound healing.  The device is 
removed by lifting one edge and peeling the device from the skin. The 
device is made of polymeric materials, utilizes a non-latex, pressure 
sensitive skin adhesive.  The device contents are provided sterile in 
an intact and unopened package.
Federal (USA) law restricts this device to use by or on the order of a 
physician.
Caution
The Zip™ 16 Surgical Skin Closure Device is indicated for use during 
and after skin incision procedures to approximate skin and hold 
together the skin edges until healing can take place.  
Intended Use
1. Do not use where adhesion cannot be obtained.  Potential causes 
of inadequate adhesion are presence of exudate, skin oils, 
moisture or hair.  
2. Do not use on infected wounds.
3. Do not use in high tension wounds which cannot be easily ap-
Contraindications
1. The development of postoperative edema may cause skin shear-
ing, skin blistering or loss of adhesion to occur.  
2. Application of any surgical tape or adhesive skin closure may 
result in skin stripping upon removal.
3. As with all adhesive products applied to the skin, a small per-
centage of individuals may experience allergic reaction and/or 
hypopigmentation or hyperpigmentation following removal.  
4. The effect of petroleum-based ointments when used in conjunc-
tion with this device is unknown.
5. Do not use if device becomes damaged during the procedure.  
Risk of device failure if device is damaged.
6. Single use device.  Do not reuse.  Risk of device failure or infec-
tion if reused.
Warnings
1. Skin should be clean, dry and free of exudate, skin oils, excess 
prep residue or hair for adequate adhesion.
2. If applied to regions such as joints where the skin surrounding the 
incision is substantially strained, carefully monitor wound closure 
integrity as mobility is increased.
3. In areas of high body contour, the ability of the device to conform 
and adhere to the application site should be assessed carefully 
prior to application.

the length of the incision.  Do not use excessive force or pull in a 
direction that is away from the incision.  To aid in the removal of the 
device, medical adhesive remover may be used.  Continuously wipe 
a soaked cotton ball or swab along the lifted edge of the device as it 
is gently pulled along the incision.  Adhesive residue may be removed 
with soap and water.
