Abstract
A self-expanding endoluminal stent-graft includes a conventional wire stent and a tubular deformable material constructed of filaments and having a density and geometry such that when ends of the tubular material are pulled apart, the diameter of the tubular material decreases to one half to one tenth of its original diameter. The tubular deformable material is affixed to the interior or exterior of the self-expanding stent, preferably with an elastomeric adhesive. A biocompatible porous elastomeric liner is preferably affixed to the interior of the deformable member with an elastomeric adhesive. The tubular deformable member is preferably a PET mesh. The elastomeric adhesive is preferably a melt adhesive used in conjunction with a fibrous or porous layer which is applied to the exterior of the stent with a padding applicator to push the adhesive through the interstices of the stent onto the graft material. A second embodiment of the invention provides a bifurcated (e.g. Y-shaped) graft material.
