An improved method for high-volume production of coated stents with highly uniform stent coatings using a roll coating technique is provided. In a first embodiment, uncoated stents are placed onto rotating stent holders with automated stent handling equipment. The holders are mounted on an endless conveyer belt which advances the stents toward a stent coater. As the stents advance through the coater, the holders rotate, thereby rolling the stents about their longitudinal axes as coating material is sprayed toward them, ensuring the stents are uniformly coated on their exterior and interior surfaces. After the conveyer turns to carry the coated stents back toward the loading area, the rotating stents pass again through the coating spray, downstream of the initial coating location, thereby increasing the efficient utilization of the coating material. The conveyer then advances the coated stents to an unloading area for removal before the holders return to the stent loading area to receive new stents.

Metallic stents are treated with a gaseous species in a plasma state under conditions causing the species to polymerize and to be deposited in polymerized form on the metallic stent surface prior to the application of a drug-polymer mixture, which is done by conventional non-plasma deposition methods. The drug-polymer mixture once applied forms a coating on the stent surface that releases the drug in a time-release manner and gradually erodes, leaving only the underlying plasma-deposited polymer. In certain cases, the plasma-deposited polymer itself erodes or dissolves into the physiological medium over an extended period of time, leaving only the metallic stent. While the various polymers and drug remain on the stent, the plasma-deposited polymer enhances the adhesion of the drug-polymer anchor coating and maintains the coating intact upon exposure to the mechanical stresses encountered during stent deployment.
