Patent ID: 8377110

Claim:
An endolumenal prosthesis having a lumenal surface and an ablumenal surface, comprising: a tubular wire support with proximal and distal ends and a central lumen extending therebetween, the wire support comprising at least two axially adjacent tubular segments, each segment comprising a series of proximal and distal bends connected by a length of wire, wherein the wire support is radially compressible into a first, reduced cross sectional configuration for translumenal navigation to a treatment site in a body lumen and self expandable to a second, enlarged cross sectional configuration for deployment at the treatment site in the body lumen; and a uniform porous tubular ePTFE sheath on the wire support, the tubular sheath having a sheath proximal end region and a sheath distal end region, wherein the sheath is porous and configured to inhibit sufficient cellular ingrowth through the wall of the sheath that would permit the formation of a viable neointimal layer on the lumenal surface of the sheath at the sheath proximal and distal end regions without a coating on the sheath that would inhibit cellular ingrowth, wherein the sheath is formed from a single ply of ePTFE and wherein a wall thickness of the sheath is the thickness of the single ply of ePTFE.
