Abstract
An intravascular stent includes an eluting sheath fabricated from a mesh for controlled release of therapeutic drugs and for delivery of the therapeutic drugs in localized drug therapy in a blood vessel. The eluting sheath is attached to at least a portion of an outside surface area of the stent structure and is fabricated from a mesh designed to neck down in response to a radially outward directed force resulting in the uniform expansion of the stent. The eluting sheath can be loaded with at least one therapeutic drug for the release thereof at a treatment site to facilitate repair of a damaged vessel. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen.
