Humacyte Acellular Tissue Engineered Vessel (ATEV) in Patients With Vascular Trauma

This is a prospective, multicenter, multi cohort, non-randomized phase 2/3 study in adult patients with life or limb threatening vascular trauma which requires surgical repair. There will be an extremity cohort and a torso cohort. The extremity cohort will include patients who require repair of a vessel contained to the upper or lower extremity. The torso cohort includes patients who require repair of vessels within the thorax (excluding the heart), abdomen, and retroperitoneum. Subjects will be implanted with an ATEV as an interposition vessel or bypass using standard vascular surgical techniques. There is no control arm. The active study duration for each study participant will be 36 months from implantation or until ATEV failure/ removal/ death, if earlier. Follow up after month 12 will involve the capture of information on assessments performed at "standard of care" routine clinic visits or by telephone follow up with the patient or his/her physician with physical exam and ultrasound at month 24 and month 36.
