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 core that is biodegradable with an outer shell formed from a polymeric material that is biodegradable. Additionally, therapeutic agents may be incorporated into the microstructure or the bulk material.

Claims

1. A substantially tubular intraluminal scaffold comprising:

a plurality of hoop components configured as the primary radial load bearing elements of the intraluminal scaffold; and

one or more connector elements interconnecting the plurality of hoop components, wherein at least one of the plurality of hoop components and the one or more connector elements comprises a composite structure formed from a bioabsorbable metallic material and a bioabsorbable polymeric material.

2. The substantially tubular intraluminal scaffold according to claim 1, further comprising one or more therapeutic agents affixed to the bioabsorbable metallic material.

3. The substantially tubular intraluminal scaffold according to claim 1, further comprising one or more therapeutic agents affixed to the bioabsorbable polymeric material.

4. The substantially tubular intraluminal scaffold according to claim 3, wherein the one or more therapeutic agents are affixed to a surface of the bioabsorbable polymeric material.

5. The substantially tubular intraluminal scaffold according to claim 3, wherein the one or more therapeutic agents are distributed throughout the bioabsorbable polymeric material.

6. The substantially tubular intraluminal scaffold according to claim 3, wherein the one or more therapeutic agents are distributed within portions of the bioabsorbable polymeric material.
