The HAVG is a sterile, non-pyrogenic, acellular tubular graft composed of human collagens and other natural extra-cellular matrix proteins. Upon implantation, it is anticipated (based on pre-clinical studies) that the collagen-based matrix comprising the graft will be infiltrated with host cells and re-modeled by the host. This will result in a vascular structure more similar to the histological composition of the native vascular tissue that may improve graft longevity and be less likely to become infected.
