Abstract

An endovascular prosthesis for implantation in a body passageway. The prosthesis comprises an elongate tubular wall comprising an annular portion for occlusion of a section of the body passageway. The annular portion comprises a first porous section and a non-porous section. In one embodiment, the non-porous section may comprise a cover material. In another embodiment, the non-porous section may comprise a series of slits, microcuts, slots, apertures and the like which serve to impede the flow of bodily fluid therethrough resulting in occlusion of an aortic disease condition located exteriorly adjacent to the deployed prosthesis.
