The purpose of this study is to assess the safety and efficacy of a novel, tissue-engineered vascular prosthesis, the Human Acellular Vessel (HAV).
The HAV is intended as an alternative to synthetic materials and to autologous grafts in the creation of an above-knee femoro-popliteal bypass graft in patients with peripheral arterial disease.

Experimental: Human Acellular Vessel (HAV)
HAV implantation to study participants.
Biological: HAV implantation
Patients will be implanted with a Human Acellular Vessel (HAV) as an above-knee femoro-popliteal bypass graft using standard vascular surgical techniques.
Other Name: Human Acellular Vessel
- Change in HAV characteristics [ Time Frame: From day 5 to month 24 after HAV implantation. ]The incidence of aneurysm formation, anastomotic bleeding or rupture, graft infection and irritation/inflammation/infection at the implantation site will be assessed by Doppler ultrasound and tabulated.
- Change in HAV patency rate [ Time Frame: From day 5 to month 24 after HAV implantation. ]Determine the patency (primary, primary assisted and secondary) rate of the Humacyte HAV by Doppler ultrasound.
- Change in frequency and severity of Adverse Events [ Time Frame: From day 1 to month 24 after HAV implantation. ]Frequency and severity of AEs of each patient will be documented.
- Change in hematology, coagulation and clinical chemistry parameters [ Time Frame: From baseline to week 26 after HAV implantation. ]Change from baseline in hematology, coagulation and clinical chemistry parameters.
- Change from baseline in Panel Reactive Antibody (PRA) [ Time Frame: From baseline to week 26 after HAV implantation. ]Assess changes in the Panel Reactive Antibody response over 6 months after graft implantation.
- Development of IgG antibodies [ Time Frame: From baseline to week 26 after HAV implantation. ]Determine whether IgG antibodies to the extracellular matrix material are formed in response to implantation of the HAVG over the 6 months after implantation.
- HAV patency rates [ Time Frame: At months 6, 12, 18 after HAV implantation. ]To determine the patency rates of the graft (primary, primary assisted and secondary).
- Graft interventions [ Time Frame: At days 5, 15, weeks 6, 12, 16, months 12, 18, 24 after HAV implantation. ]Determine the rates of interventions needed to maintain / restore patency in the graft.
- Effect of graft implantation on PAD symptoms [ Time Frame: From baseline to weeks 6, 12, 26, months 12, 18, 24 after HAV implantation. ]Assessment of any effect of graft implantation on claudication, rest pain and ischemic ulcers.
- Effect of graft on ankle-brachial index (ABI) [ Time Frame: From baseline to weeks 6, 12, 26, months 12, 18, 24 after HAV implantation. ]Assessment of any effect of the graft on ankle-brachial index (ABI).
