Brief Summary:

30 patients will be enrolled in a prospective, multi-center, one-arm study, enrolling patients with claudication and chronic limb ischemia scheduled for lower limb venous bypass grafting on clinical grounds with single segment autologous saphenous vein.

Subjects will be followed for 5 years, with follow up visits at 1, 3, 6, 12 months, 2, 3, 4, 5, years post operation.

Inclusion Criteria:

  1. Patient scheduled for infrainguinal peripheral artery bypass surgery with single segment autogenous saphenous vein.
  2. Rutherford classification 3-6

  9. Planned above ankle amputation on ipsilateral limb within 4 weeks of index procedure.
  10. Patients with history of hypercoagulable conditions.
  11. Patients with significant stenoses distal to the planned anastomotic site and any other known conditions that could adversely affect graft patency.
  12. Concomitant life-threatening disease likely to limit life expectancy to less than 2 years.
  13. Contraindication to recommended study medications
  14. Participating in any other investigational study for either drug or device which can influence collection of valid data under this study.
