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.

* Target lesion length \>=4 cm; no more than 3 cm outside stent at either end
* Vessel diameter \>=5 mm and \<=7 mm
* At least one widely patent tibial or peroneal artery to the foot

Exclusion Criteria:

* Patient is pregnant or breast feeding
* Evidence of acute limb ischemia
* Life expectancy \<12 months
* CVA within 60 days of screening

* Known contraindication to aspirin, antiplatelet and anti-coagulation therapies
* Uncontrolled hypercoagulability
* Present or suspected systemic infection in target limb
* Serum creatinine \>= 2.5 mg/dl unless dialysis dependent
* Previous treatment to target vessel within 3 months of study procedure
* Drug eluting stents or covered stents in target lesion
* 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)
* Tibial artery containing a \>50% Diameter Stenosis (DS) by visual estimate after popliteal
* Grade 4 or 5 stent fracture affecting target stent or proximal to the target stent, or where evidence of stent protrusion into the lumen is noted on angiography in 2 orthogonal views.
B: Inclusion Criteria:

* Rutherford Clinical Category 2-4
* At least 18 years of age
* Is able and willing to provide written informed consent prior to study specific procedures

Exclusion Criteria:

* Has a life expectancy of less than 24 months
* Is pregnant, of childbearing potential not taking adequate contraceptive measures, or nursing
* Has one or more of the contraindications listed in the SilverHawk/ TurboHawk or Cotavance IFUs
C: Inclusion Criteria:

* Symptomatic ≥ 70% stenosis of the SFA (Rutherford stage 2-6)
* Written informed consent

Exclusion Criteria:

* Acute ischemia and/or acute thrombosis of the SFA
* Untreated ipsilateral iliac artery stenosis \>70%
* Previous stenting of the SFA
* Popliteal stenosis \>70%
* Severe renal insufficiency
D: Inclusion Criteria:

* Written informed consent
* Age \> 18 years
* If female patient with child bearing potential, patient may not be pregnant at the study entry and must utilize reliable birth control for the duration of her participation into the study
* Patient is willing and able to comply with the specified follow-up evaluation
* Critical Limb Ischaemia, this is Fontaine stage III (ischaemic rest pain) and IV (ischaemic ulcers or gangrene) or Rutherford category 4 (ischaemic rest pain), 5 (minor tissue loss) or 6 (major tissue loss)
* Stenotic (\>50% luminal loss) or occluded infrapopliteal artery, including the tibiofibular trunk, the anterior tibial artery, the posterior tibial artery and the peroneal artery, with a lesion length ≤ 60 mm
* Artery to be treated with a diameter more tham or equal to 2mm and less than or equal to 4mm
* Patent common iliac, external iliac, superficial femoral and popliteal artery on the ipsilateral side prior to randomisation, possibly after treatment during the same session
* At least one patent crural (anterior tibial, posterior tibial or peroneal) artery with expected unobstructed runoff to ankle level after treatment

Exclusion Criteria:

* Acute limb ischaemia
* Subacute limb ischaemia which requires thrombolysis as first treatment modality
* Active bleeding or bleeding diathesis
* Recent (less than 3 months) hemorrhagic stroke or other any other CNS abnormality with increased risk of haemorrhage, such as intracranial neoplasm, arteriovenous malformation, intracranial aneurysm or aneurysm repair
* Gastrointestinal or genitourinary bleeding of clinical significance within the previous 6 weeks before treatment
* Aneurysm in common femoral, superficial femoral or popliteal artery on the ipsilateral side
* Revascularization involving the same limb within 30 days prior to the index procedure or planned revascularization of the same limb within 30 days of the index procedure
* Previous implanted stent at the index site
* Life expectancy of less than 6 months or other factors making clinical follow-up difficult
* Known allergy to acetylsalicylic acid (aspirin), clopidogrel, heparin or paclitaxel
* Known allergy to contrast media
* Known heparin induced thrombocytopenia (HIT type 2)
* Patient unable or unwilling to tolerate anticoagulant, anti-platelet therapy or contrast media
* Creatinine clearance \< 20 ml/min (as derived from Cockcroft-Gault or MDRD formula)unless patient is on hemodialysis
* Aneurysm in common femoral, superficial femoral or popliteal artery on the ipsilateral side
* Severely calcified lesions with expected resistance to stenting
* Poor inflow due to ipsilateral stenoses or occlusions of the iliac or femoropopliteal arteries that cannot be treated during the same session
* Significant vessel tortuosity or other parameters prohibiting access to the lesions and/or delivery of the stent
* Patients without (expected) distal runoff to the index site
* Previous implanted stent at the index site
