Abstract
A method of manufacturing a medicated prosthesis such as a stent. The method includes forming a stent out of porous metal and loading a therapeutic agent into the pores of the metal. In one embodiment the stent is formed from a sintered metal wire, sheet, or tube and can include adding a coating to the stent. When the stent is implanted into the vasculature of a patient, the therapeutic agent in the stent dissipates into the tissue of the vasculature proximate the stent.
Claims38
A method of manufacturing a stent for providing local delivery of a therapeutic agent at an implantation site, comprising:
- sintering metallic fibers into a sintered stent material having a plurality of porous holding cavities open to one side;
- forming the sintered stent material into a stent;
- and
- loading a therapeutic agent into the cavities of the stent prior to implanting the stent at the implantation site.
