Brief Summary:

This is a multi-center, clinical pilot-study of ProEndoTecc Vascular Grafts (6, 7 or 8 mm Diameter) as superficial femoral artery bypass/interponate.

The aim of this study is to demonstrate safety of implantation, patency and durability of a new type of vascular graft.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 33 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Multicenter, Clinical Pilot-Study of ProEndoTecc Vascular Grafts (6, 7 or 8 mm Diameter) as Superficial Femoral Artery Bypass/Interponate
Study Start Date : March 2010
Actual Primary Completion Date : November 2012
Actual Study Completion Date : November 2012

Intervention Details:
  • Device: ProEndoTecc Vascular Graft
    Implantation of the device as an interponate / bypass of the superficial femoral artery
    Other Name: ProEndoTecc Vascular Graft Prosthesis

Primary Outcome Measures :
  1. Primary patency of device [ Time Frame: 6, 12, 24 months after implatation ]

    Primary Patency of treated arterial segment at 6 month after intervention. Primary Patency is defined by objective demonstration via colour-coded Doppler sonography or angiography that the entire length of the graft remain patent with no further intervention required for symptomatic recurrent disease.

    In case this information is not available, primary patency might be declared, if any the following criteria are fulfilled: Present ABI increased of ≥0.1 compared to preoperative status Present PAD-Grade according to Rutherford increased by one degree Palpable pulse distal of prosthesis.

Secondary Outcome Measures :
  1. Guarding Safety variables [ Time Frame: 6,12, 24 months after implantation ]
    • Peri-interventional monitoring resp. haemorrhages, haematomas
    • Aneurysm in the grafted segment
    • Fistula to the grafted segment
    • Fibrosis at and around implantation site
    • Death

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Female or male patient from 18 to 89 years of age
  • Superficial femoral artery occlusion from 5 to 40 cm in length (above the knee joint),
  • Patient must present with intermittent claudication, with resistance to medical therapy and exercise or critical ischemia,

Exclusion Criteria:

  • Bleeding diathesis
  • Patient has known coagulation disorders including hypercoagulability
  • Presence of one or several previously placed endo-prosthesis or grafts in the diseased extremity (below iliacs)
  • Other than 6-8 mm diameter graft is needed.
  • Patients PAD state is in Fontaine Grade IV, Rutherford Grade 6 (Patient has active infection or pronounced necrosis in the region of graft placement)
  • Patient has an acute embolic arterial occlusion
  • Life-expectancy less than 6 month due to co-morbidity or other situation that would make the patient an unlikely candidate for follow-up visits

  • Patient is in need of, or is scheduled for, a cardiac surgical procedure or a different vascular surgical procedure
  • Pregnant or breast feeding female patients
  • Multiple graft (implant) needed
  • Patients unable to understand the full meaning of the informed consent
  • Subjects who, in the opinion of the investigator, will be inappropriate for inclusion into this trial or will not comply with requirements of the study
  • Subjects who are imprisoned (according to MPG §20.3)
  • Patients who are lawfully kept in an institution
  • Participation in this trial at an earlier stage
  • Current participation in another clinical trial
