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 supportive 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.

A multiple-component bifurcating expandable supportive endoluminal graft comprising: a plurality of expandable supportive endoluminal components which are deployed individually at a selected location within a body vessel, each said supportive endoluminal graft component being radially compressible for endoluminal insertion and radially expandable for deployment at a desired location within a body vessel; one of said expandable supportive endoluminal components is a trunk component, said trunk component including a tubular supporting member and a trunk liner positioned along said tubular supporting member, said trunk liner having a generally cylindrical body portion and at least two leg portions, each said leg portion defining a leg opening; at least one other of said expandable supportive endoluminal components is a generally cylindrical supportive leg component; and said generally cylindrical supportive leg component and one of said leg portions of the trunk component, when said leg component and trunk component are deployed within the body vessel, are telescopically positioned with respect to each other.
