Abstract
A vascular graft at least partially formed from porous hollow fibers, with at least some of the porous hollow fibers being located adjacent an inner surface of the vascular graft. The vascular grafts of the invention have a relatively small pore size for promoting tissue growth while inhibiting bleeding during the healing process. The porous hollow fibers used to form the vascular grafts of the invention further provide a storage situs for temporarily holding a drug or other material for delivery into the blood stream during the healing process. This storage capability may also be used for holding an inert gas while providing the graft with greater resilency and cushioning characteristics than achievable with presently available vascular grafts.
