入选标准

  • Age ≥18 years old
  • Rutherford Classification: 3-5 in target limb; Rutherford Classification 3 subjects may be enrolled but will be capped to a limit of 20% of the total enrollment (no more than two Rutherford Class 3 subjects may be enrolled into the study).
  • Able and willing to provide informed consent, and comply with follow-up visits at both 30 days and 180 days (6 months)
  • Able to comply with antiplatelet therapy as required
  • Reference Vessel Diameter is ≥2.0 mm and ≤4.0 mm
  • Target lesion length is ≤150 mm
  • De novo or restenotic target lesion(s) (except for in-stent restenotic lesion) with stenosis ≥70%, by visual estimation, in a single limb in a single native vessel
  • Inflow artery is patent, free from significant lesion stenosis (≥50% stenosis is considered significant) as visually confirmed by angiography. Note: Successful inflow artery treatment is allowed during the index procedure. Successful inflow artery treatment is defined as attainment of residual diameter stenosis ≤50% without major vascular complications (absence of flow limiting dissection, embolic event)
  • Guidewire has successfully crossed the target lesion(s) within the true lumen

排除标准

  • Females who are pregnant or lactating
  • Pre-existing illness with life expectancy <1 year
  • Known or suspected systemic infection
  • Significant gastrointestinal bleeding or any coagulopathy that would preclude the use of anti-platelet therapy
  • Subjects with a diagnosis of osteomyelitis and are currently on IV antibiotic therapy
  • Endovascular or surgical procedure performed on the target lesion within 3 months of the index procedure
  • Subjects who in the opinion of the Investigator have underlying kidney disease and may be at risk for contrast-induced acute kidney injury (AKI)
  • Subjects who in the opinion of the Investigator have uncontrolled diabetes
  • Allergic to iodine/radiopaque contrast that in the opinion of the Investigator cannot be adequately pre-treated
  • History of Coronary Artery Bypass Graft (CABG), unstable angina pectoris, or myocardial infarction within 30 days and/or hemorrhagic stroke within 90 days
  • Subjects scheduled to undergo a planned major amputation of the lower limb above the ankle on the target limb
  • Allergic to any of the components of the atherectomy device system
  • Intraprocedural complications prior to use of the investigational device
  • Subjects with a positive COVID-19 test within the last 60 days and/or is symptomatic, at the Investigator's discretion
  • Subject with other medical, social or psychological problems that, in the opinion of the investigator, preclude them from receiving this treatment, and the procedures and evaluations pre - and post-treatment
  • Presence of flow-limiting stenosis (>50% diameter reduction) or occlusion of inflow vessels that was not successfully treated (<50% residual stenosis without flow limiting dissection) before the study intervention/prior to the point of enrollment
  • No obvious angiographic evidence of flow to the foot following inflow treatment
  • Co-existing aneurysmal disease requiring treatment
  • Presence of vessel dissection at the target lesion requiring stent placement
  • Clinical/angiographic evidence of distal embolization or acute thrombus
  • Severe calcification that is measured >10mm in length and circumferential
  • Prior stent placement in the target lesion
