Abstract
Abstract The present invention provides a soft-tissue prosthesis which is formed from a tubular textile substrate and a liner. The liner is affixed to the intraluminal surface of the tubular textile portion of the soft-tissue prosthesis to form a fluid-tight barrier on the intraluminal surface of the prosthesis. The liner is preferably formed from a polymer. Thus, the soft-tissue prosthesis formed in accordance with the present invention provides the advantages of both a textile prosthesis and a polymer prosthesis.

A method of repairing a diseased blood vessel of a patient comprising the steps of: removing a diseased portion of said blood vessel from said patient, leaving a first open end and a second open end of said blood vessel; inserting a tubular prosthesis between said first and second open ends of said blood vessel, said tubular prosthesis being formed from a textile substrate having a fusible fiber therein and an intraluminal surface, with a polymeric liner affixed to said intraluminal surface, said liner being affixed to said textile substrate by heating said prosthesis to a temperature above the melting temperature of said fusible fiber and below the melting temperature of said liner, wherein said liner fuses to said textile substrate and renders the tubular prosthesis blood-tight; and securing said tubular prosthesis to said first and second open ends of said blood vessel to allow blood to flow therethrough.
