Low profile, durable, reinforced ePTFE composite graft

摘要

A composite graft having a first seamless tubular layer comprising biocompatible first polymeric material and having a luminal surface and an exterior surface; a biocompatible reinforcing member arranged in a pattern to define a second tubular layer, the second tubular layer being disposed over the exterior surface of the first tubular layer; and a third seamless tubular layer comprising biocompatible second polymeric material and having a luminal surface and an exterior surface, the luminal surface of the third tubular layer being securably disposed over the second tubular and over the first tubular layer; wherein the tubular layers define a wall of the graft, the wall having a wall thickness of less than 0.1 mm. Desirably, the graft wall thickness is less than 0.05 mm.
