Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Ischemic rest pain for more than 2 weeks or ulceration or gangrene of the foot or toes (Rutherford Becker Category 4, 5 or 6)
  • Willing and able, as evaluated by the PI, to provide Informed Consent
  • Willing to undergo up to 5 years of clinical follow up visits as scheduled
  • Angiographic pattern of infrainguinal disease that can be reasonably managed either by surgery or plaque excision in the first instance
  • Reconstitution of at least one patent target tibial segment below the knee which provides run-off to the foot
  • The patient must be >18 years of age
  • Target lesion(s) is located at or below the level of the superficial femoral artery
  • Target lesion(s) is >50% stenosed by quantitative vascular angiography
  • Ability to take at least one of the following types of medications: anti- platelet or anti-thrombotic therapy

Exclusion Criteria:

  • Patient has cardiac or cardiovascular comorbidities that would make surgery inappropriate
  • Patient has terminal or Stage 4 cancer
  • Patient has extensive gangrene that requires both a Below-the-Knee amputation and a revascularization procedure
  • Previous stent in the target lesion
  • Active infection at planned incision site
  • The patient is a pregnant woman
  • The patient has significant suprainguinal or Common Femoral disease that can not be treated either prior to or during the index procedure
  • Target Lesion is a Chronic Total Occlusion (CTO) that is greater than 15cm in length and has severe, continuous calcification
