An Open-label Study to Assess the Safety and Efficacy of SYMVESS® as a Vascular Conduit in Adolescents With Extremity Arterial Injury.

The goal of this study is to assess the safety and efficacy of Symvess in sexually mature adolescents (17 years of age or younger) who require a vascular conduit to repair an extremity arterial injury when autologous vein graft is not available. The main questions the study aims to answer are: Safety and tolerability of Symvess in adolescent patients? Determine patency of Symvess over 12-months Evaluate the long-term amputation-free rate Determine the ability of Symvess to remain infection-free Participants will undergo implantation of Symvess to repair an arterial injury in an extremity using standard surgical techniques. Following implantation, patients will be followed for up to 12-months where they will undergo standard safety assessments, patency assessments using Duplex Ultrasound, and examination of the surgical site.
