Brief Summary:
The objective of this study is to evaluate the performance of the In.Pact Admiral DEB for the treatment of popliteal lesions in comparison with literature results of stent treatment in popliteal lesions

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 100 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: In.Pact Flexion, a Physician Initiated Trial Investigating the Performance of the In.Pact Admiral Drug-eluting Balloon for the Treatment of Popliteal Lesions
Study Start Date : April 2014
Estimated Primary Completion Date : December 2018
Estimated Study Completion Date : December 2018

Arm Intervention/treatment
Experimental: InPact Admiral
Patients treated with the InPact Admiral balloon for popliteal lesions
Device: InPact Admiral DEB

Primary Outcome Measures :
  1. Primary Patency at 12 months [ Time Frame: 12 months ]
    defined as absence of a hemodynamically significant stenosis on duplex ultrasound (systolic velocity ratio no greater than 2.4) at the target lesion and without TLR within 12 months.

Secondary Outcome Measures :
  1. Technical success [ Time Frame: 1 day post-op ]
    defined as the ability to cross and dilate the lesion and achieve residual angiographic stenosis no greater than 30%.

  2. Primary Patency at 1 and 6-months [ Time Frame: 1 and 6 months ]
    defined as absence of a hemodynamically significant stenosis on duplex ultrasound (systolic velocity ratio no greater than 2.4) at the target lesion and without TLR within the time of procedure and the given follow-up

  3. Clinical success at 1, 6 and 12-months [ Time Frame: 1, 6 and 12 months ]
    defined as an improvement of Rutherford classification at 1-, 6- and 12-month follow-up of one class or more as compared to the pre-procedure Rutherford classification

  4. Serious Adverse Events [ Time Frame: up to 12 months ]
    defined as a clinical event that is fatal, life-threatening, or judged to be severe by the investigator; resulted in persistent or significant disability; necessitated surgical or percutaneous intervention; or required prolonged hospitalization

  5. Survival rate [ Time Frame: up to 12 months ]
    all-cause death ratio

  6. Target Lesion Revascularization [ Time Frame: up to 12 months ]
    defined as a repeat intervention to maintain or re-establish patency within the region of the treated arterial vessel plus 5 mm proximal and distal to the treated lesion edge

  7. Limb Salvage Rate [ Time Frame: up to 12 months ]
    defined as absence of major amputation. Major amputation is defined as amputation at or above the ankle, as opposed to minor amputation, being an amputation at or below metatarsal level, preserving functionality of the foot)

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • - De novo, restenotic or reoccluded lesion located in the popliteal artery, with or without superficial femoral artery involvement

  • Prior to enrollment, the guidewire has crossed target lesion
  • Patient is eligible for treatment with the In.Pact Admiral drug-eluting balloon
  • The target lesion, visually estimated, has a maximal length of 14 cm and can be categorized as either a type A or B lesion according the TASC II guidelines
  • The target lesion has angiographic evidence of stenosis or restenosis > 50% or occlusion which can be passed with standard guidewire manipulation
  • 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, irrespective of whether or not outflow was re-established by means of previous endovascular intervention.

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

  • 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, atherectomy 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.
