Abstract
The present invention provides a stent-graft assembly. The assembly comprises at least one stent framework and a graft member. The graft member is positioned adjacent an inner surface of the stent framework and everted over an outer surface of the stent framework to enclose at least a portion of the stent framework. The assembly may further comprise a therapeutic agent that is enclosed by the graft member. Elution openings may be formed in the graft member to preferentially elute a therapeutic agent into the wall rather than the lumen of a vessel into which the stent-graft assembly is placed.
