Abstract
An endoprosthesis may be implanted in the region of an anatomical canal that is experiencing impairment. An exterior surface wall of the endoprosthesis bears projecting studs that cooperate with the wall of the anatomical canal so as to hold the endoprosthesis in position. One of the projecting studs is hollow and acts as a reservoir for a product that is active against the impairment.
