The invention is directed to mechanisms and methods that reduce the delamination of a therapeutic agent from a stent. The mechanisms include holes (channels, wells, and other hole configurations), protrusions, sintered metal cores, clamps/staples, pins, and stainless steel shields. Cette invention concerne des mécanismes et des procédés qui réduisent le décollement d'un agent thérapeutique d'une endoprothèse. Les systèmes d'orifices (canaux, puits et autres configurations à orifices), de protrusions, de noyaux métalliques frittés, de pinces/agrafes, de broches et de protections en acier inoxydable comptent parmi les mécanismes de l'invention.
