About the study
Who can take part
INCLUSION CRITERIA
Inclusion Criteria:
- Subjects age 18 and older
- Subject or the subject's legal representative is willing and able to provide consent before any study-specific test or procedure is performed, signs the consent form, and agrees to attend all required follow-up visits
- Subject has documented chronic, symptomatic lower limb ischemia defined as Rutherford categories 2 - 4, and is eligible for percutaneous peripheral vascular intervention
Stenotic, restenotic or occlusive lesion(s) located in the native SFA and/or PPA, and meet all of following angiographic criteria by visual assessment:
i. Atherosclerotic lesion with diameter stenosis ≥70% ii. Guidewire must cross lesion(s) within the true lumen, without a sub-intimal course by physicians performed, based on visual estimate iii. Minimum vessel diameter proximal to the lesion ≥ 3 mm and < and =6 mm iv. Lesion length of single or multiple focal stenosis or chronic total occlusion (CTO) lesion can be up to 15 cm long v. Target lesion located at least 3 cm above the inferior edge of the femur
Patent infrapopliteal and popliteal artery, i.e., single distal runoff or better with at least one of three vessels patent (< 50% stenosis by visual assessment) to the ankle or foot with no planned intervention
EXCLUSION CRITERIA
Exclusion Criteria:
- Target lesion is located in the iliac artery or above the SFA
- Target lesion stenosis < 70%
- Target lesion is moderately to severely angulated (> 30°) or torturous at treatment segment
- Target lesion/vessel previously treated with drug-coated balloon within 12 months prior to the index procedure
- Target lesion/vessel previously treated with atherectomy, laser or other debulking devices prior to the index procedure
- Target lesion/vessel with in-stent restenosis
- Subjects who have undergone prior surgery or endovascular intervention of SFA/PPA in the target limb to treat atherosclerotic disease within 3 month prior to the index procedure
- Use of drug-coated devices, or laser or any other debulking devices other than Jetstream System (such as CTO devices or cutting balloon) in the target limb during the index procedure
- History of major amputation in the target limb
- Documented life expectancy less than 12 months due to other medical co-morbid condition(s)
- Known hypersensitivity or contraindication to contrast dye that, in the opinion of the investigator, cannot be adequately pre-medicated
- Known history of coagulopathy or hypercoagulable bleeding disorder
- Known hypersensitivity/allergy to the investigational devices or protocol related therapies (e.g., nitinol, stainless steel or other stent materials, and antiplatelet, anticoagulant, thrombolytic medications)
- Platelet count < 80,000 mm3 or > 600,000 mm3 or history of bleeding diathesis
- Undergoing hemodialysis or concomitant renal failure with a serum creatinine > 2.0 mg/dL (176.8umol/L)
- History of myocardial infarction (MI), stroke/cerebrovascular accident (CVA) or gastrointestinal bleeding within 6 months prior to the enrollment
- Unstable angina pectoris at the time of enrollment.
- History of severe trauma, fracture, major surgery or biopsy of a parenchymal organ within past 14 days
- Pregnant, breast feeding, or plan to become pregnant in the next 12 months
- 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)
- Septicemia at the time of enrollment
- Presence of outflow lesions in the target limb requiring intervention during the index procedure
- Presence of other hemodynamically significant lesions in the target limb requiring intervention within 30 days of enrollment
- Acute ischemia and/or acute thrombosis of the target lesion/vessel prior to the index procedure
- Presence of aneurysm in the target vessel
- Perforated vessel as evidenced by extravasation of contrast media prior to the enrollment
