7. Requires use of adjunctive therapies (i.e., laser, atherectomy, cryoplasty, scoring/cutting balloons, brachytherapy).
8. Has severe calcification that precludes adequate PTA treatment.

Cohort 2: General Inclusion Criteria:

1. Has symptomatic leg ischemia, requiring treatment of the SFA and/or popliteal artery.

3. Is between 18-85 years old.
4. Has life expectancy >1 year.
5. Is able and willing to provide written informed consent prior to study specific procedures.
6. Is willing and capable of complying with the required follow-up visits, testing schedule and medication regimen.
7. History of previous femoropopliteal nitinol stenting which is suspect for in-stent restenosis.
8. 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:

1. 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.
2. 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.
3. 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). Edge restenosis may be treated provided the lesion extends no more than 3 cm outside the margin of the stent (proximal and/or distal margin).

2. Identification of any lesion of the native vessel (excludes ISR) above the target stent in the femoropopliteal segment >50% that is not successfully treated prior to index procedure (e.g. complication requiring additional treatment) or with final residual stenosis >30% documented by angiography. 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).
