| titleOfInvention | MULTI-LAYER BIO-REPLACABLE BLOOD VESSEL PROSTHESIS. |
| abstract | Process for forming a multilayer blood vessel prosthesis (10). Each layer is formed from bioreplaceable materials which include those produced by contacting collagen with an aminopoly-saccharide and subsequently covalently crosslinking the resulting polymer, polymers of hydroxyacetic acid and the like. Cross flow filtration molding and wet extrusion molding are two processes which are particulary useful for forming the inner layer (12) of the blood vessel prosthesis (10) the outer layer (14) of the blood vessel prosthesis (10) is preferably formed by freeze drying a dispersion of the bioreplaceable material onto the inner layer(s). The disclosed blood vessel prosthesis (10) is a multilayer structure with each layer having a porosity and other physicochemical and mechanical characteristics selected to maximize the effectiveness of the blood vessel. The prosthesis (10) functions initially as a thromboresistant conduit with mechanical properties which match those of the adjacent natural blood vessel. Eventually, the prosthesis (10) functions are a regeneration template which is replaced by new connective tissue that forms during the healing process following attachment of the prothesis. |
