Abstract:
1. A bioabsorbable, magnesium-reinforced polymeric endoprosthesis comprising an expandable cylindrical body formed from at least one erodible polymer having one or more endoprosthesis support elements fabricated therefrom, wherein said erodible polymer confers sufficient radial strength upon the endoprosthesis support element in order for the endoprosthesis to restore fluid flow through a diseased lumen, and said one or more endoprosthesis support elements further includes at least one reinforcing element comprising magnesium, wherein said endoprosthesis comprises a luminal surface and a vascular surface, and said one or more endoprosthesis support elements define a central lumen along said luminal surface, wherein when a cross section is taken of an endoprosthesis support element from an end view, said endoprosthesis support element cross section comprises a trapezoidal shape, and wherein said reinforcing element encapsulates said one or more endoprosthesis support elements.
