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.

L'invention concerne une méthode de fabrication d'une prothèse médicamenteuse, telle qu'un tuteur. La méthode comprend les étapes suivantes : fabriquer un tuteur dans un métal poreux et introduire un agent thérapeutique dans les pores du métal. Dans une configuration, le tuteur est construit à partir d'un fil, d'une feuille ou d'un tube de métal fritté et peut comprendre un revêtement. Lorsque le tuteur est implanté dans le réseau vasculaire d'un patient, l'agent thérapeutique du tuteur se dissout dans les tissus du vaisseau près du tuteur.
