入选标准

  • Patients must between 18 and 85 years old, without gender limit.
  • Patients who can understand the purpose of the trial, voluntarily participate in and sign the informed consent form, and complete the 1-year follow-up.
  • Subject has lower extremity atherosclerotic occlusive disease with symptomatic Critical Limb Ischemia (CLI).
  • Rutherford Becker Clinical Category 3-
  • The target lesion is below the popliteal artery (including bifurcation).
  • The target lesion is located in the proximal 2/3 of native infrapopliteal vessels or tibiofibular trunk.
  • The target lesion stenosis is ≥70% or occlusion of no more than two infrapopliteal arteries (including the anterior and/or posterior tibial and/or peroneal artery and/or tibiofibular trunk).
  • The length of target lesion is ≤200mm, which could be covered by no more than two stents, with vessel diameter of 2.25-4.25 mm.

排除标准

  • Severe renal insufficiency, hepatic dysfunction (Cr>2 times of normal limit or renal dialysis, ALT or AST > 5 times of normal limit).
  • Surgery in target vessel before treatment.
  • Volume reduction surgery in target vessel before treatment.
  • Thrombosis in target vessel, or acute thrombosis requiring thrombolysis and thrombectomy.
  • Systematic coagulation disorder or hypercoagulability.
  • Lower extremity arteries surgery or thrombolytic therapy in the ipsilateral extremity in the past 6 weeks.
  • Stroke occurs within 3 months before surgery, or stroke occurs with severe hemiplegia aphasia sequelae more than 3 months before treatment.
  • Acute myocardial infarction or angina pectoris within 30 days before treatment.
  • In-stent restenosis.
  • Guide wire cannot pass target lesion.
  • Previously treated with drug eluting balloon within 1 year before treatment.
  • More than two infrapopliteal arteries needed treatment.
  • The inflow tract (including ipsilateral iliac artery, femoral artery, popliteal artery) has lumen stenosis >30% with or without intervention.
  • The inflow tract (including ipsilateral iliac artery, femoral artery, popliteal artery) has > 150 mm stenosis or occlusion before treatment.
  • Aneurysm of lower extremity artery.
  • Thromboangiitis obliterans (Buerger's disease).
  • Significant (≥ 50% stenosis) lesion in a distal outflow artery that would be perfused by the target vessel and that requires treatment at the time of the index procedure.
  • Patients known to be allergic to aspirin, heparin, Plavix, contrast agents, Sirolimus, poly lactic acid polymer, iron, zinc and their degradation product, and those who cannot tolerate postoperative dual anti-platelet therapy.
  • Patients who have a history of disease related to iron overload or iron disorder, such as hereditary hemochromatosis, etc.
  • Patients who are participating in another clinical trial that has not yet completed its primary endpoint.
  • Pregnant or those who plan pregnancy during the clinical investigation follow-up period.
  • Angiography suggests intraoperative thromboendarterectomy, percutaneous transluminal rotational atherectomy or laser therapy are needed.
  • Patients have life expectancy ≤ 1 year.
  • Patients who are not suitable for participating the trial judged by investigator.
