Endovascular prosthesis having a layer of biological tissue
First Claim
1. A method for forming a graft for insertion in a blood vessel, the blood vessel having an inside surface that at least partially defines a conduit for directing blood flow, said method comprising the steps of:
- providing an expandable support member having a mesh-like structure with inner and outer surfaces, the outer surface for engaging and adhering to the inside surface of the blood vessel;
harvesting a layer of peritoneal tissue comprising an inner lining of a serous membrane having an uninterrupted inwardly facing surface for extending confluently with the inside surface of the blood vessel to provide resistance to thrombosis and platelet deposition as blood flows through the conduit;
forming the layer of peritoneal tissue into a desired shape; and
attaching the layer of peritoneal tissue to the inner surface of the support member.

Abstract
An apparatus (10) for grafting of a blood vessel (12) and a method of forming the apparatus (10) is provided. The apparatus (10) comprises an expandable support member (16) having inner and outer surfaces (36 and 34). The outer surface (34) of the expandable support member (16) is for engaging and adhering to an inside surface (68) of the blood vessel (12). A layer of biological tissue (14) is attached to the inner surface (36) of the support member (16). The layer of biological tissue (14) has an uninterrupted inwardly facing surface (50) for extending confluently with the inside surface (68) of the blood vessel (12) to provide resistance to thrombosis and platelet deposition.
