An endoluminal graft which is both expandable and supportive is provided either in a longitudinal form or in a bifurcated form. The graft expands between a first diameter and a second, larger diameter. The support component is an expandable stent endoprosthesis. A cover, liner, or 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 supportive graft is at its second diameter. Preferably, the elastomeric wall material is a polycarbonate urethane.

[ What is claimed is:] [1.] An expandable supportive endoluminal graft, comprising:a tubular supporting component with a longitudinal axis, an internal surface, and an external surface, said tubular supporting component having a network of land areas with open areas defined between said land areas, said tubular supporting component being expandable from a first diameter at which the expandable supportive endoluminal graft is insertable into a body pathway to a second diameter, said second diameter being greater than said first diameter;a liner constructed of an essentially inert biocompatible material, said liner applied to said internal surfaces; anda cover constructed of an essentially inert biocompatible material, said cover applied to said external surface;wherein said liner is bonded to said cover at locations defined by said open areas of the tubular supporting component; andsaid liner and said cover are both made from a porous elastomeric material that provides a structure which allows normal cellular ingrowth, said porous elastomeric material selected from the group consisting of grafts constructed by electrostatic spinning of polymeric fibers, elution of particulate materials from polymeric sheeting, and solvent phase inversion from polymeric sheeting.
