ABSTRACT:
A polylumenal implantable device comprises a body defining a plurality of capillary lumina. The prosthetic device is suitable for implantation in a patient as an arterial or venous bypass graft or shunt, or intra-organ implant as well as other purposes. The improved prosthetic device has increased surface area and preferably a three-dimensional porosity for encouraging the harboring of, for example, endothelial cells, as well as for receiving organized deposition of material such as genetically enhanced cell types. A method for providing a bioactive material to a patient includes the steps of providing a polyluminal implantable organ comprising an implantable body defining a plurality of capillary lumina, treating the interior surfaces of the lumina with a bioactive material or plasma polymerization, and implanting the prosthetic device in the patient so that bodily fluids of the patient come into contact with the treated interior surfaces.
