Abstract
Abstract An endoluminal graft which is both expandable and supportive is provided in a form suitable for use in a bifurcated body vessel location. The graft expands between a first diameter and a second, larger diameter. The support component is an expandable stent endoprosthesis. A cover, a liner, or both a cover and a liner are applied to the endoprosthesis in the form of a stretchable wall material that is porous, elastomeric and biocompatible in order to allow normal cellular invasion upon implantation, without stenosis, when the expandable and support graft is at its second diameter. The supportive endoluminal graft is preferably provided as a plurality of components that are deployed separately at the bifurcated body vessel location. <IMAGE>
