Abstract
Abstract An implantable intraluminal device includes a first porous elongate tube with first and second opposed ends and an exterior surface and an interior luminal surface. A radially expandable member is disposed about the exterior surface of the first tube. A second porous elongate tube is disposed concentrically over the first tube and the radially expandable member and is secured to the first tube so that the radially expandable member is transversely mobile within a pocket formed by the securement of the first tube to the second tube.
