Study Overview

Brief Summary

This study will assess the results up to 12 months with the Protégé EverFlex stent (ev3) in patients presenting with a narrowing or blocking at the level of the knee artery, which leads to a limited walking distance, rest pain or non-healing ulcers.

Inclusion Criteria

  • General Inclusion criteria
  • De novo, restenotic or reoccluded lesion located in the popliteal artery, with or without superficial femoral artery involvement
  • Patient presenting a score from 2 to 5 following Rutherford classification
  • Patient is willing to comply with specified follow-up evaluations at the specified times
  • Patient is >18 years old
  • Patient (or their legal representative) understands the nature of the procedure and provides written informed consent, prior to enrolment in the study
  • Prior to enrollment, the guidewire has crossed target lesion
  • Patient is eligible for treatment with the self-expanding nitinol EverFlex (ev3) stent
  • Angiographic Inclusion Criteria
  • The target lesion has angiographic evidence of stenosis or restenosis > 50% or occlusion which can be passed with standard guidewire manipulation
  • The target lesion, visually estimated, has a maximal length of 14 cm and can be categorized as either a type A or B lesions according the TASC II guidelines
  • Target vessel diameter visually estimated is >3.5mm and <7.5 mm
  • There is angiographic evidence of at least one-vessel-runoff to the foot

Exclusion Criteria

  • Presence of another stent in the target vessel that was placed during a previous procedure
  • Presence of an aortic thrombosis or significant common femoral ipsilateral stenosis
  • Previous by-pass surgery in the same limb
  • Patients for whom antiplatelet therapy, anticoagulants or thrombolytic drugs are contraindicated
  • Patients who exhibit persistent acute intraluminal thrombus of the proposed lesion site
  • Perforation at the angioplasty site evidenced by extravasation of contrast medium
  • Patients with known hypersensitivity to nickel-titanium
  • Patients with uncorrected bleeding disorders
  • Aneurysm located at the level of the SFA and/or popliteal artery
  • Female patient with child bearing potential not taking adequate contraceptives or currently breastfeeding
  • Life expectancy of less than twelve months
  • Ipsilateral iliac treatment before the target lesion procedure with a residual stenosis > 30% or ipsilateral iliac treatment conducted after the target lesion procedure
  • Use of thrombectomy, artherectomy or laser devices during procedure
  • Any patient considered to be hemodynamically unstable at onset of procedure
  • Patient is currently participating in another investigational drug or device study that has not completed the entire follow up period.

Outcomes

Primary Outcomes

primary patency

Time Frame: 12 months post-procedure

primary patency at 12 months, defined as a target lesion without a hemodynamically significant stenosis on duplex ultrasound (systolic velocity ratio no greater than 2.4) and without TLR within 12 months

Secondary Outcomes

  • Technical success(1 day post-procedure)
  • Primary patency rate at 6-, 12-month follow-up.(6-, 12-month follow-up)
  • Clinical success(6-, 12-month follow-up)
  • tent fracture rate at 12-month follow-up(12-month follow-up)
  • Serious adverse events(1 year)
