Abstract
An endoprosthesis assembly for percutaneous deployment on a balloon catheter is disclosed. The assembly includes a radially expandable stent overlied by a tubular, low profile stent cover wrapped over the stent. The wrapped cover is thermally set to maintain its low profile wrapped configuration during deployment of the assembly. At the treatment site, the balloon portion of the catheter is inflated causing the stent to expand radially and the stent cover to unwrap and open to conform to the expanded configuration of the stent.
