NCT ID:
NCT01108861
Eligibility Criteria:
General Inclusion Criteria:
* Patient presenting with lifestyle-limiting claudication, rest pain or minor tissue loss (Rutherford classification from 2 to 5)
* 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)
* Minimum of 1.0cm of healthy vessel (non-stenotic) both proximal and distal to the treatment area
* Popliteal artery is patent at the intercondylar fossa of the femur to P3
* Target vessel diameter visually estimated to be \>4mm and \<7.6 mm at the proximal and distal treatment segments within the SFA
* Guidewire and delivery system successfully traversed lesion
* There is angiographic evidence of at least one-vessel-runoff to the foot, that does not require intervention (\<50% stenotic)
Exclusion criteria :
* Untreated flow-limiting aortoiliac stenotic disease
* Presence of a chronic total occlusion, i.e. a complete occlusion of the failed bare stent that cannot be re-opened with thrombolysis or does not allow easy passage of the guidewire by the physician
* Any previous surgery in the target vessel
* Severe ipsilateral common/deep femoral disease requiring surgical reintervention
* Perioperative unsuccessful ipsilateral percutaneous vascular procedure to treat inflow disease just prior to enrollment
* Femoral or popliteal aneurysm located at the target vessel
* Non-atherosclerotic disease resulting in occlusion (e.g. embolism, Buerger's disease, vasculitis)
* 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.
