Criteria

Inclusion Criteria:

  • Patient is ≥18 years of age
  • Patient is Rutherford category 2-4
  • De novo lesion in the SFA or popliteal artery with a diameter stenosis ≥50%
  • Target lesion is a de novo occlusion that can be successfully pre-dilated resulting in a lesion of <99%
  • Target lesion stenosis has a length of ≤100 mm based on visual assessment
  • Target vessel reference diameter is ≥3.0 mm and ≤7.0 mm based on visual assessment
  • Angiographic evidence of distal runoff defined as minimum one (1) patent tibial artery with a straight flow to the foot
  • Patient is willing and able to provide written informed consent prior to any study specific procedure
  • Patient is willing and able to comply with specified follow-up evaluations at the specified times

Exclusion Criteria:

  • Any prior intervention in the intended target lesion including 10 mm proximal or distal from the intended treatment area
  • Evidence of thrombus in the target vessel
  • Prior ipsilateral or contralateral lower limb arterial bypass
  • Treatment of ipsilateral lesions during the index procedure or planned treatment after the index procedure
  • Target lesion is severely calcified
  • Any known allergies and / or intolerances to the following: ASA, Clopidogrel, Heparin, contrast agents (that cannot be adequately pre-medicated).
  • Any planned surgery within 30 days of the study procedure.
  • Renal failure (serum creatinine > 2.0 mg/dL)
  • Female with childbearing potential without a negative pregnancy test
  • Patient has had an organ transplant
  • Patient is currently participating in an investigational drug or device study which has not reached the primary endpoint yet or which clinically interferes with the endpoints of this study
  • In the investigator's opinion, the patient has a severe co-morbid condition(s) that could limit the ability to participate in the study
