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
