Cagent Vascular, LLC 150 Strafford Avenue #315 Wayne, PA 19087 ## 510(k) Summary [as required by 21 CFR 807.92(c)] ### Serranator® PTA Serration Balloon Catheter Cagent Vascular, LLC # 510(k): K193181 | DATE PREPARED | April 15, 2020 | |-----------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------| | APPLICANT INFORMATION | Carol Burns/President & CEO<br>150 Strafford Avenue #315<br>Wayne, PA 19087 | | CONTACT INFORMATION | Carol A. Burns, President and CEO<br>Phone: (610) 688-2006<br>Fax: (610) 688-2667<br>Email: cburns@cagentvascular.com | | TRADE NAME | Serranator® PTA Serration Balloon Catheter | | DEVICE CLASSIFICATION | Class 2 per 21 CFR §870.1250 | | CLASSIFICATION NAME | Percutaneous Catheter | | PRODUCT CODE | PNO | | PREDICATE DEVICES | Predicate Device:<br>AngioSculpt® PTA Scoring Balloon Catheter (K142983)<br>Reference Device:<br>Serranator® Alto PTA Serration Balloon Catheter (K163380) | {4}------------------------------------------------ ### 5.1 Intended Use/Indications for Use The Serranator® PTA Serration Balloon Catheter is intended for dilatation of lesions in infrapopliteal arteries. Not for use in the coronary or neuro-vasculature. ### 5.2 Device Description The Serranator® PTA Serration Balloon Catheter is an over-the-wire (OTW) balloon dilatation catheter designed to perform percutaneous transluminal angioplasty (PTA) for peripheral indications as described in the Indication for Use statement. The Serranator® has a nylon semicompliant balloon with three embedded external metal strips or scoring elements. The unique scoring elements are serrated, designed to modify the plaque by creating linear, interrupted scoring along the endoluminal surface. This occurs during balloon inflation and is designed to aid arterial expansion. #### 5.3 Comparison with Predicate Devices A comparison of the Serranator® PTA Serration Balloon Catheter (Serranator) and predicate device shows that the technological characteristics such as the components, design, materials, sterilization method, and operating principle of the Serranator are identical or similar to the currently marketed AngioSculpt® PTA Scoring Balloon Catheter (AngioSculpt) (K142983) and the Serranator® Alto PTA Serration Balloon Catheter (Serranator Alto) (K163380), predicate and reference devices respectively. The technological differences are that the scoring elements of Serranator® are interrupted, rather than a continuous metal configuration such as the AngioSculpt device. The unique scoring elements are serrated, designed to create linear, interrupted scoring along the endoluminal surface. The intended use of the subject device and the predicate device is similar. The indications for use of the Serranator® PTA Serration Balloon Catheter are similar to that of the Serranator Alto reference device. #### 5.4 Non-Clinical Testing/Performance The Serranator® PTA Serration Balloon Catheter has been tested through the design verification activities to demonstrate that the device meets design input requirements. The following tests were conducted and passed all requirements (see Table 3.1 below). {5}------------------------------------------------ | Test | Result | |----------------------------------|--------| | Shipping, environmental stresses | Pass | | Flex/Kink | Pass | | Visual Inspection | Pass | | Delivery, Deployment, Retraction | Pass | | Fatigue | Pass | | Rated Burst/Compliance | Pass | | Torsion | Pass | | Corrosion | Pass | | Tensile Test of Joints | Pass | Table: 5.1 Summary of Non-Clinical/Performance Testing Bench testing in accordance with FDA guidance[1], ASTM and ISO standards was performed on sterile, unaged (Time Zero) and accelerated aged (Time Aged) test samples of Serranator® PTA Serration Balloon Catheter. The non-clinical testing demonstrated that the Serranator® met all acceptance criteria. Performance data demonstrate that the device functions as intended and has an acceptable safety and effectiveness profile. #### 5.5 Biocompatibility FDA guidance document Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing" Guidance for Industry and Food and Drug Administration Staff, June 16, 2016, ISO-10993 Biological Evaluation of Medical Devices Part 1: Evaluation and Testing, and ISO-10993 Biological Evaluation of Medical Devices Part 12: Sample Preparation and Reference Materials were followed in selecting and conducting the biocompatibility testing of the Serranator PTA Serration Balloon Catheter. Biocompatibility testing was conducted on sterile, finished devices manufactured using the manufacturing processes which will be used for the cleared devices. Testing confirmed that the Serranator is non-cytotoxic, non-sensitizing, not systemically toxic, nonthrombogenic, and non-hemolytic. ^[1] Guidance for Industry and FDA Staff - Non-Clinical Engineering Tests and Recommended Labeling for Intravascular Stents and Associated Delivery Systems, April 2010. Only the sections associated with Delivery Systems were applied to Serranator. {6}------------------------------------------------ Table 3.2 provides a list of the various tests completed and passed. | Test | Results | |----------------------------------|---------| | <b>Cytotoxicity</b> | Pass | | <b>Sensitization</b> | Pass | | <b>Irritation</b> | Pass | | <b>Systemic Toxicity (acute)</b> | Pass | | <b>Pyrogenicity</b> | Pass | | <b>Hemocompatibility</b> | Pass | Table 5.2: Biocompatibility Tests In addition to the tests indicated in Table 5.2, thrombogenicity evaluation was conducted as part of the Acute Porcine Study. #### 5.6 Animal Studies An animal study was performed to assess usability, performance and acute thromboresistance of the Serranator® PTA Serration Balloon Catheter in swine peripheral arteries. In accordance with general FDA animal study guidelines and ISO-10993-4 methodology, a total of two porcine test subjects were used for assessment. No adverse events including filling defects, dissections, thrombus formation or perforations occurred in this study. #### 5.7 Cadaver Studies A diseased cadaver study was not performed using the Serranator® PTA Serration Balloon Catheter (Serranator) as this testing was conducted in the reference device, the Serranator® Alto PTA Serration Balloon Catheter (Serranator Alto) submission (K163380). The results between the subject device and the Serranator Alto (reference) were not expected to differ as both devices have the same function, design and mechanism of action. A cadaver artery assessment was performed to determine the medial thickness of non-diseased infrapopliteal arteries. These data were used to determine an appropriate strip height for safety. Arteries assessed showed minimal atherosclerotic disease ranging from mild disease to no calcification. Average medial thickness varied significantly between popliteal, anterior tibial, posterior tibial, tibial-peroneal, and peroneal sections. {7}------------------------------------------------ #### 5.7 Conclusion The Serranator® PTA Serration Balloon Catheter has similar intended use and similar technological characteristics such as components, design, materials, sterilization method, and operating principles as the predicate and reference devices. Performance data demonstrates that the device functions as intended. Data presented in this 510(k) Submission support that the Serranator® PTA Serration Balloon Catheter is substantially equivalent to the predicate AngioSculpt® PTA Scoring Balloon Catheter and reference Serranator® Alto PTA Serration Balloon Catheter.
