  20. Current participation in another investigational drug or device clinical study that has not completed the primary endpoint at the time of enrollment or that clinically interferes with the current study endpoints (Note: studies requiring extended follow-up for products that were investigational, but have become commercially available since then are not considered investigational studies)
  21. Septicemia at the time of enrollment
  22. Presence of outflow lesions in the target limb requiring intervention during the index procedure
  23. Presence of other hemodynamically significant lesions in the target limb requiring intervention within 30 days of enrollment

5. Study Description

Brief Summary
This clinical study is a prospective, non-randomized, multicenter, single-arm study to demonstrate the acceptable safety and performance of the JETSTREAM™ Atherectomy System (Jetstream) used during percutaneous peripheral vascular intervention in patients with occlusive atherosclerotic lesions in the native SFA and/or PPA. It is intended that all patients with qualifying lesions would be considered for enrollment and treated with the Jetstream System.
Detailed Description
study objectives: To evaluate the safety and effectiveness of JETSTREAM™ Atherectomy System (Jetstream) for treating symptomatic Chinese patients with occlusive atherosclerotic lesions in native superficial femoral artery (SFA) and/ or proximal popliteal arteries (PPA)during percutaneous peripheral vascular intervention. Planed Indications for use: The Jetstream System is intended for use in atherectomy of the peripheral vasculature and to break apart and remove atherosclerotic disease, debris, and thrombus from the SFA and/or PPA. Primary Safety Endpoint: Major Adverse Event (MAE), defined as all-cause death, target limb unplanned major amputation and/or target lesion revascularization (TLR), within 30 days post index procedure Primary Effectiveness Endpoint: Acute reduction of percent diameter stenosis (%DS) post atherectomy but prior to any adjunctive therapy, when compared to its baseline diameter stenosis (absolute mean percentage).
