Abstract
Biocompatible materials may be configured into any number of implantable medical devices including intraluminal stents. The biocompatible material may comprise metallic and non-metallic materials in hybrid structures. In one such structure, a device may be fabricated with one or more elements having an inner metallic frame that is not degradable with an outer shell formed from a polymeric material that is biodegradable by extrusion blow molding. Additionally, therapeutic agents may be incorporated into the microstructure or the bulk material.
