Device Description Summary The Coronary Dilatation Balloon Catheter (VesPenetrator®, VesTraveler® and VexPander®) is a percutaneous transluminal coronary angioplasty (PTCA) is indicated for balloon dilatation of the stenotic portion of a coronary artery. Balloon diameters ranged from 1.5mm to 4.0mm. The balloon is made of Nylon material with a rated burst pressure of 16 atmospheres (atm) for both VesPenetrator and VesTraveler, and 18atm for VexPander. The proximal shaft of the catheter is composed of a female {4}------------------------------------------------ luer connector bonded to a PTFE coated stainless steel tube. The proximal shaft joins with a smooth transition to a distal shaft composed of an outer tube of nylon or Pebax and a tri-extrusion inner tube with a balloon welded to both tubes at the distal tip. Two radiopaque platinum marker bands are positioned within the balloon shoulders. The inner tube accepts a standard 0.014 inch guidewire. The guide wire enters the catheter's tip and advances coaxially out the distal Rx port, thereby allowing both coaxial guidance and rapid exchange of catheter with a single standard length guide wire. Two marked sections of 5mm length each located on the proximal shaft indicate catheter position relative to the tip of the brachial artery or the guide tube of the femoral artery. # 5. Intended Use/ Indications for Use The VesPenetrator®, VesTraveler® Coronary Dilatation Balloon Catheters are indicated for: · balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis in patients evidencing coronary ischemia for the purpose of improving myocardial perfusion • balloon dilatation of a coronary artery occlusion for the treatment of acute myocardial infarction The VexPander® Coronary Dilatation Balloon Catheters are indicated for: - · balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis in patients evidencing coronary ischemia for the purpose of improving myocardial perfusion - balloon dilatation of a coronary artery occlusion for the treatment of acute myocardial infarction - in-stent restenosis - · post-delivery expansion of balloon expandable coronary stents ## 6. Comparisons with Predicate Device Comparisons of the subject devices, coronary dilatation balloon catheter (VesPenetrator®, VesTraveler®, VexPander®), and the predicate device, Sapphire® NC plus coronary dilatation catheter shows that the subject device such as indication for use, prescription use and design (such as effective length, guide wire size, proximal shaft diameter, distal shaft diameter, monorail catheter, markers bands, sterilization method) are identical. In the terms of balloon diameter and balloon compliance, VesPenetrator® & VesTraveler® are identical to Sapphire® coronary dilatation catheter, and VexPander® is identical to Sapphire® NC plus coronary dilatation catheter, details are provided in Table 1. Comparisons of the subject devices to the reference device show that the balloon length of subject device covered by reference device Mozec™ NC-Rx PTCA balloon dilatation catheter, the coating of subject device is identical to reference device Tamarin Blue® PTCA RX dilatation catheter, therefore the balloon length and coating do not raise any new questions of safety or effectiveness. Similar nominal pressure and rated bust pressure will be satisfied with technical requirement in compliance and do not raise any new questions of safety or effectiveness. The biocompatibility of subject device conforms to FDA guidance of biological evaluation of medical devices and do not raise any new questions of safety effectiveness. {5}------------------------------------------------ ## 7. Performance Data The subject device, coronary dilatation balloon catheter (VesTraveler®, VexPander®), was subjected to the following applicable testing to assure reliable design and performance under the specified testing parameters and ensure that the design and construction are suitable or its intended use as recommended by the Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters (FDA; September 8, 2010): The results of these tests provided reasonable assurance that the subject device has been designed and tested to assure conformance to the requirements for its intended use. No new questions of safety or performance issues were raised during the testing and, therefore, these devices may be considered substantially equivalent to the predicate device. ## Biocompatibility Testing: Per ISO 10993-1:2018 and FDA guidance, the following tests were performed to ensure the biocompatibility of the subjective device. - In vitro cytotoxicity, per ISO 10993-5:2009 - Intracutaneous reactivity, per ISO 10993-10: 2010 - . Skin sensitization, per ISO 10993-10: 2021 - . Acute systemic toxicity, per ISO 10993-11: 2017 - . Hemocompatibility (hemolysis, complement activation (SC5b-9, C3a), coagulation (partial thromboplastin time, prothrombin time), in vivo thromboresistance), per ISO 10993-4:2017 - . Material mediated pyrogenicity, per USP General Chapter <151> ### Non-clinical Testing/Performance Data: The following tests were completed and support the coronary dilatation balloon catheter (VesPenetrator®, VesTraveler®, VexPander®) - . Catheter visual inspection - Catheter dimensional inspection - Guide wire compatibility test - Guiding catheter compatibility test - . Haemostasis valve compatibility - . Balloon preparation, deployment and retraction - Balloon fatigue test - Balloon rated burst pressure (RBP) - Balloon compliance - . Balloon inflation and deflation time - Catheter bond strength - Tip pull test - Flexibility and kink test - Torque strength test - . X-Ray detectability - Particle contamination test - . Balloon rated burst pressure (RBP; in stent) {6}------------------------------------------------ - Balloon fatigue (repeat balloon inflations; in stent) - . Bacterial endotoxin testing ## 8. Conclusion Based on the indications for use, technological characteristics, and performance testing, the coronary dilatation balloon catheter (VesPenetrator®, VesTraveler®, VexPander®) has been shown to shown to be appropriate for its intended use and is considered to be substantially equivalent to the predicate device.
