The OPC for Optimal Delivery of Paclitaxel for the Prevention of Endovascular Restenosis - Above and Below the Knee

The purpose of this study is to assess the safety and efficacy of paclitaxel administration using the occlusion perfusion catheter (OPC) for the prevention of restenosis in infrainguinal de novo, restenotic femoropopliteal and infrapopliteal stenoses and occlusions, and in-stent restenosis. Subjects will be treated with the endovascular intervention selected by the treating physician in SFA reference vessels ranging from 4mm to 7mm in diameter and infrapopliteal vessels ranging from 2mm to 4mm. Following the achievement of optimal interventional results (less than thirty (30) percent residual stenosis without stenting) the OPC will be placed at the interventional treatment area and paclitaxel will be delivered to the treated segment. Data will be collected to assess acute safety, long-term safety and durability to demonstrate the safety and efficacy of paclitaxel delivered with the ACT, Inc. OPC device.
