Abstract
Endoprostheses including composites, and methods of making the endoprosthesis, are disclosed. The composites include at least a first material and a second material having different chemical compositions from each other.
Claims29
1-37. (canceled)
A method of making an endoprosthesis, the method comprising:
- introducing a powdered second material into at least some interconnected channels defined by interconnected portions of a first structure comprising a first material to form a dry composite, the first and second materials having different chemical compositions,
- consolidating the dry composite under pressure, and
- using the consolidated composite to form at least a portion of the endoprosthesis.

A method of making an endoprosthesis, the method comprising:
- introducing a second material into at least some interconnected channels defined by interconnected portions of a first structure comprising a first material to form a composite, the first and second materials having different chemical compositions,
- densifying the composite into a billet;
- and
- shaping the billet to form at least a portion of the endoprosthesis.
A method of making an endoprosthesis, the method comprising:
- introducing a second material comprising titanium into at least some interconnected channels defined by interconnected portions of a first structure comprising tantalum to form a composite, and
- using the composite to form at least a portion of the endoprosthesis.
