Claims13
An endoprosthesis, comprising:
- a generally tubular member having a lumen and including at least one component selected from the group consisting of struts, bands, and combinations thereof,
- wherein the at least one component comprises a bioerodible material selected from the group consisting of bioerodible metals, bioerodible metal alloys, and combinations thereof, the bioerodible material defining a plurality of non-interconnected closed pores, and wherein the at least one component has a porous first region and a second porous region, the non-interconnected closed pores in the first region having a first average volume and the non-interconnected closed pores in the second region having a second average volume that is greater than the first average volume.
An endoprosthesis, comprising:
- a generally tubular member comprising a bioerodible material selected from the group consisting of bioerodible metals, bioerodible metal alloys, and combinations thereof, the bioerodible material defining a plurality of non-interconnected closed pores, the generally tubular member having a first region defining an interior surface of the generally tubular member and a second region defining an exterior surface of the generally tubular member,
- wherein the non-interconnected closed pores in the first region have a first average volume, and the non-interconnected closed pores in the second region having have a second average volume that is greater than the first average volume.
