Abstract
Endoprostheses include an endoprosthesis wall that includes a surface layer that includes a metallic material and that defines a plurality of discrete pores. A porous material is disposed in one or more pores of the surface layer. The endoprostheses can, for example, deliver a therapeutic agent, such as a drug, in a controlled manner over an extended period of time.
Claims37
An endoprosthesis, comprising:
- an endoprosthesis wall comprising
- a surface comprising a metallic material defining a plurality of discrete pores, and
- a porous magnesium oxide or iron oxide material disposed in one or more of the discrete pores.
An endoprosthesis, comprising:

2 more elements
A method for making an endoprosthesis, comprising:
- forming on a surface of an endoprosthesis preform a plurality of discrete pores;
- depositing a first material into one or more of the discrete pores;
- corroding the first material to form a second material in the discrete pores;
- and
- treating the second material in the discrete pores in a locally high alkaline environment to form a third material.
