Outcome Measures

Primary Outcomes (2)

  • The primary safety endpoint is defined as freedom from all cause death, unplanned index limb amputation, and target lesion revascularization.

    through 30 days

  • The primary efficacy endpoint is defined as stent patency via Color Duplex Ultrasound (Peak Velocity Ratio ≤ 2.5).

    3 months

Secondary Outcomes (4)

  • Clinically-Driven Target Lesion Revascularization (i.e., with documented preintervention evidence of at least 50% diameter stenosis (quantitative angiographic ≥ 50% or PSVR > 2.5).

    12 months

  • Change in Rutherford Classification compared to pre-implant.

    12 months

  • Stent Patency via Color Duplex Ultrasound (Peak Systolic Velocity Ratio ≤ 2.5).

    12 months

  • Stent Fractures.

    12 months

Study Arms (1)

Stent placement

EXPERIMENTAL
Device: Stenting of atherosclerotic lesion(s)

Interventions

Stenting of atherosclerotic lesions post pre-dilatation of lesion(s)

Also known as: SAMBA Stent and Delivery System

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Screening
  • Patient must be ≥ 21 years of age with life expectancy \> 1 year.
  • Symptomatic leg ischemia requiring treatment of the superficial femoral and/or popliteal artery (Rutherford category 2-4; claudication, rest pain).
  • Patient must be a suitable candidate for PTA and stenting.
  • Patient is willing and able to return to the site of the investigation at the specified study intervals and undergo follow-up requirements.
  • The patient or legal representative has provided written informed consent using a form that is reviewed and approved by the EC for the Clinical Site.
  • Pre-Intervention
  • Target lesion has ≥ 50% stenosis as demonstrated angiographically.
  • Lesion length ≤ 15 cm.
  • Reference vessel diameter of 5 to 6 mm.
  • Patient has at least 1 vessel run-off prior to treatment.

You may not qualify if:

  • Screening
  • The subject is pregnant or will become pregnant during the study or has any other condition that would preclude having x-rays. (Pre-menopausal women must have a negative pregnancy test within 7 days of the procedure.)
  • Patients who have experienced a cardiovascular accident (CVA) or a myocardial infarction (MI) within 3 months prior to the procedure.
  • Subject has had or plans to have a surgical or interventional procedure within 30 days before or after the implantation procedure of the SAMBA Stent.
  • Existing hemorrhagic disease or coagulation problems or inability to take dual anti-platelet therapy.
  • Contrast allergy that cannot be corrected with medication (e.g. steroids, etc.).
  • Subject has 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.
  • Patient is currently participating in another investigational drug or device study.
  • Pre-Intervention
  • Uncorrectable severe aorto-iliac occlusive disease or severe common femoral artery stenosis preventing access or limiting inflow (e.g., stenosis greater than 50%).
  • Uncorrectable occlusive disease limiting outflow (e.g., stenosis greater than 50%)
  • Patients with previous surgery in the target vessel or stent that will be closer than 2 cm to either edge of SAMBA Stent(s).
  • Lack of 1 cm of healthy vessel proximal to proximal target
  • Lack of popliteal reconstitution (at least 2 cm of normal distal popliteal).
  • Inability to cross the lesion with a guidewire.
  • +2 more criteria
