介入・治療
実験的：Acellular Tissue Engineered Vessel (ATEV)
Patients with life or limb threatening traumatic injury to an arterial vessel in the limb or torso, other than the heart, will be implanted with the Humacyte ATEV as an interposition vessel or bypass using standard vascular surgical techniques.
生物学的：Acellular Tissue Engineered Vessel (ATEV)
The investigational medicinal product (IMP) - the Acellular Tissue Engineered Vessel (ATEV) is a sterile acellular tubular graft composed of human collagen types I and III and other extracellular matrix proteins, including fibronectin and vitronectin which can be used for arterial bypass or reconstruction in patients with life or limb threatening vascular trauma. The vessel is 6 mm in diameter and approximately 42 cm in length. The product is supplied on a silicone mandrel immersed in sterile phosphate buffered saline in a sealed and labeled plastic container. The ATEV is implanted using standard vascular surgical techniques similar to placement of predicate peripheral vascular prostheses.

メジャーの説明
時間枠
Primary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the All HAV Group
時間枠：30 days from time of implantation
Rate of primary patency at the specified milestone post-implantation, evaluated across the entire overall study population who received the Human Acellular Vessel (HAV). Primary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the evaluation milestone, without requiring any intervening surgical or endovascular interventions to maintain or re-establish flow.
30 days from time of implantation
Primary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the Extremity Community-Acquired Trauma Subgroup
時間枠：30 days from time implantation
Rate of primary patency at 30 days post-implantation, evaluated strictly within the sub-cohort of participants presenting with non-iatrogenic, community-acquired extremity vascular trauma. Primary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the 30-day evaluation milestone, without requiring any intervening surgical or endovascular interventions to maintain or re-establish flow.

Secondary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the All HAV Group
時間枠：30 days from time of implantation
Rate of secondary patency at the specified milestone post-implantation, evaluated across the entire overall study population who received the Human Acellular Vessel (HAV). Secondary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the evaluation milestone, including vessels that became occluded but were successfully restored to patency via intervening endovascular or surgical re-intervention (e.g., thrombectomy, thrombolysis, or patch angioplasty).

時間枠：30 days from time of implantation
The percentage of participants who remained entirely free from a confirmed, adjudicated infection of the implanted Human Acellular Vessel (HAV) conduit through the specified follow-up milestone, evaluated across the entire overall study population. An infection event is defined by clinical signs coupled with microbiologic confirmation from wound/perigraft cultures, or an independent clinical adjudication confirming a graft-specific infectious complication requiring targeted antibiotic therapy, surgical debridement, or explantation.
