Abstract:
1. A stent system for delivery of a therapeutic agent in a body lumen, comprising: an intravascular stent configured to contact the walls of the body lumen to maintain the patency of the vessel; and a stent cover, the stent cover defining a delivery sheath fabricated from a mesh and placed over the stent, wherein the delivery sheath contains at least one therapeutic agent in sufficient quantities for the release thereof at the treatment site, wherein at least a portion of the mesh includes a predesigned pattern of individual mesh members that are circumferentially disposed around the stent in such a way that a majority of the individual members plastically deform and neck down along their longitudinal axes such that the individual members slide relative to one another in response to a radially outward directed force due to radial expansion of the stent.
