ABSTRACT An arterial graft prosthesis comprises a first interior zone of a solid, segmented polyether-polyurethane material surrounded by a second zone of a porous, segmented polyether-polyurethane and a third zone immediately surrounding said second zone and of a solid, segmented polyether-polyurethane. The interior zone may have a lining or blood interface of a microporous zone of segmented polyether-polyurethane, and the exterior, third zone may be surrounded by a tissue interface of a microporous zone of segmented polyether-polyurethane. In some instances the exterior may be confined by a tube of substantially non- stretchable netting fastened in place at chosen, spaced intervals or other formsof reinforcement may be employed.
