Abstract
A composite intraluminal prostheses for treating a stenotic region in a blood vessel. The intraluminal prostheses including a thermally expandable stent and an open cell stent cover where the cell size is selected to be small enough to prevent plaque prolapse and the ingrowth of diseased tissue through the openings in the stent, while allowing for the re-endothelialization of the blood vessel wall with healthy tissue. The stent cover is further able to expand and contract with the stent without becoming loose upon contraction and without exerting significant resistence to radial expansion.
