简要总结
Cohort 1: Single-Arm, multicenter study to continue to assess the safety and performance of the Stellarex 035 Drug Coated Balloon (formerly known as the Cardiovascular Ingenuity (CVI) Paclitaxel-Coated PTA Balloon Catheter) in the treatment of de novo or restenotic lesions in the superficial femoral and/or popliteal arteries.
Cohort 2: To evaluate this patient population for treatment of in-stent restenotic lesions.
详细描述
Cohort 1:
The purpose of this single arm study is to continue to assess safety and performance of the Stellarex 035 DCB in the treatment of de novo or restenotic lesions in the superficial femoral (SFA) and/or popliteal arteries.
Cohort 2:
A second cohort is being added to evaluate this patient population for treatment of in-stent restenotic lesions.

排除标准

- •Cohort 1: Angiographic Exclusion Criteria:
- •Has significant stenosis (≥50%) or occlusion of inflow tract that is not successfully revascularized (<30% residual stenosis without death or major vascular complication) prior to treatment of the target lesion(s). Only treatment of target lesion(s) is acceptable after successful treatment of inflow iliac artery lesion(s).
- •Has an acute or sub-acute intraluminal thrombus within the target vessel.
- •Has in-stent restenosis or restenosis of the target lesion following previous treatment with a drug-coated balloon.
- •Has an aneurysm (at least twice the reference vessel diameter) located in the target vessel, abdominal aorta, iliac, or popliteal arteries.
- •Has perforation, dissection or other injury of the access or target vessel requiring stenting or surgical intervention prior to enrollment.
- •Has no normal arterial segment proximal to the target lesion in which duplex ultrasound velocity ratios can be measured.
- •Requires use of adjunctive therapies (i.e., laser, atherectomy, cryoplasty, scoring/cutting balloons, brachytherapy).
- •Has severe calcification that precludes adequate PTA treatment.
- •Cohort 2: General Inclusion Criteria:
- •Has symptomatic leg ischemia, requiring treatment of the SFA and/or popliteal artery.
- •Has a Rutherford Clinical Category of 2 -
- •Note: Rutherford Clinical Category 2 subjects should be entered into the study if conservative treatment has been unsuccessful.
- •Is between 18-85 years old.
- •Has life expectancy >1 year.
- •Is able and willing to provide written informed consent prior to study specific procedures.
- •Is willing and capable of complying with the required follow-up visits, testing schedule and medication regimen.
- •History of previous femoropopliteal nitinol stenting which is suspect for in-stent restenosis.
- •The patient has a resting ankle-brachial index (ABI) <0.9 or an abnormal exercise ABI (<0.9) if resting ABI is normal. Patient with incompressible arteries (ABI>1.2) must have a toe-brachial index (TBI) <0.7 in target limb.
- •Cohort 2: Angiographic Inclusion Criteria:
- •Has angiographic evidence of significant restenosis (≥50% by visual estimate) within a previously deployed femoropopliteal bare nitinol stent(s) including ISR Class I, II or III.
- •Has target limb with at least one patent (<50% stenosis) tibio-peroneal run-off vessel to the foot confirmed by baseline angiography or magnetic resonance angiography (MRA) or computed tomography angiography (CTA). Note: Treatment of outflow disease is NOT permitted.
- •Total target treatment length of in-stent restenosis must be ≥4.0 cm in length and may include a single lesion or a multifocal lesion within the femoropopliteal segment (This includes the proximal, mid, and/or distal SFA and PI, P2 and/or P3 segment of the popliteal artery).

Drug eluting stent (DES) and drug coated balloon (DCB) will not be allowed. The lesion length must be treatable with a single stent (if required). The lesion must not be contiguous with the target lesion; at least 2 cm of normal appearing vessel between the lesion and target lesion/ target stent or between deployed stent (if required) and the target lesion/ target stent.
