Title: EXCImer Laser Randomized Controlled Study for Treatment of FemoropopliTEal In-Stent Restenosis
Brief Summary: The purpose of the study is to evaluate the safety and efficacy of laser atherectomy with balloon angioplasty compared to balloon angioplasty alone in the treatment of above the knee peripheral artery in-stent restenosis.

Exclusion Criteria:

* contraindication for combined antiplatelet treatment

* need for amputation

B: General Inclusion Criteria:

* Patient is willing to comply with specified follow-up evaluations at the specified times
* Patient is \>18 years old
* Patient understands the nature of the procedure and provides written informed consent, prior to enrolment in the study
* Patient has a projected life-expectancy of at least 24 months
* Noninvasive lower extremity arterial studies (resting or exercise) demonstrate ankle-brachial index ≤0.8
* Patient is eligible for treatment with the Viabahn® Endoprosthesis (W.L. Gore)
* Male, infertile female, or female of child bearing potential practicing an acceptable method of birth control with a negative pregnancy test within 7 days prior to study procedure

Angiographic Inclusion Criteria

* Restenotic or reoccluded lesion located in a stent which was previously implanted (\>30 days) in the superficial femoral artery, suitable for endovascular therapy
* Total target lesion length between 4 and 27 cm (comprising in-stent restenosis and adjacent stenotic disease)

* Severe ipsilateral common/deep femoral disease requiring surgical reintervention
* Perioperative unsuccessful ipsilateral percutaneous vascular procedure to treat inflow disease just prior to enrollment

* No patent tibial arteries (\>50% stenosis)
* Prior ipsilateral femoral artery bypass
* Severe medical comorbidities (untreated CAD/CHF, severe COPD, metastatic malignancy, dementia, etc) or other medical condition that would preclude compliance with the study protocol or 2-year life expectancy
* Serum creatinine \>2.5mg/dL within 45 days prior to study procedure unless the subject is currently on dialysis
* Major distal amputation (above the transmetatarsal) in the study or non-study limb
* Septicemia or bacteremia
* Any previously known coagulation disorder, including hypercoagulability
* Contraindication to anticoagulation or antiplatelet therapy
* Known allergies to stent or stent graft components (nickel-titanium or ePTFE)
* Known allergy to contrast media that cannot be adequately pre-medicated prior to the study procedure
* Patient with known hypersensitivity to heparin, including those patients who have had a previous incidence of heparin-induced thrombocytopenia (HIT) type II
* Currently participating in another clinical research trial, unless approved by W.L. Gore \& Associates in advance of study enrolment
* Angiographic evidence of intra-arterial thrombus or atheroembolism from inflow treatment
* Any planned surgical intervention/procedure within 30 days of the study procedure
* Target lesion access not performed by transfemoral approach.
C: Inclusion Criteria:

* PAD with Rutherford class 1-4
* Resting ABI \<0.9 or abnormal exercise ABI \<0.9
* History of previous femoropopliteal nitinol stenting
* Angiographic significant restenosis (\>=50%)

* Ipsilateral and/or contralateral iliac stenosis \>= 50% DS that is not successfully treated prior to index procedure or with final residual stenosis \<= 30% documented by angiography
* Planned or predicted cardiovascular surgical or interventional procedures prior to completion of the 30-day follow-up
* Identification of any lesion below the target stent in the treated leg \>50% that will require preplanned or predicted treatment within 30 days(prior to the 6 month follow up)
