Abstract
An implantable intraluminal device includes a multilayer composite tubular device supporting one or more stents between the layer thereof and a method of making such a device is disclosed. A first porous elongate tube includes 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 is secured thereto so that the radially expandable member is longitudinally immobilized therebetween.
Claims19
A process for providing an implantable intraluminal device comprising:
- providing a first porous tube having first and second opposed ends, said first tube having an exterior surface and an interior luminal surface;
- providing an expandable member having opposed ends, said expandable member formed in a generally circular configuration with said ends placed immediately adjacent to and overlapping each other;
- radially disposing said expandable member about the exterior surface of said first tube;
- positioning a second porous tube concentrically over said first tube and said expandable member;
- and
- securing said first tube to said second tube, wherein said ends of said expandable member are mobile with respect to one another, said expandable member is immobilized along the axial axes of said first and second tubes.
