The present invention relates to a coating assembly and methods that employ the coating assembly to control the thickness of therapeutic or other coatings delivered to a medical device during a coating process. In one embodiment the coating assembly may include a coating plate having a coating transfer surface and a shoulder having a first height, a mandrel moveable over the coating transfer surface, and a coating dispenser positioned in fluid communication with the coating transfer surface. The invention also includes a method of coating a medical device. This method may include placing a medical device on a mandrel, dispensing coating onto a coating transfer surface of a coating plate, moving the mandrel and the medical device over the coating transfer surface of the coating plate so that coating resident on the coating transfer surface transfers to an exposed surface of the medical device, and removing the medical device from the mandrel.

Film coating medical devices

A medical device, e.g., a stent, is provided with different coatings on different surfaces, or with a coating on only one of the inside or outside surface. In accordance with certain embodiments, two different stent members are provided, one to fit inside of the other. When the two stent members are separate, both stent members are coated, each with a different composition, or only one stent member is coated. Then, one stent member is placed inside the other to form the final stent. The resulting stent has one composition on its outside surface and a different composition on its inside surface, or coating only on either the inside or outside surface.
