ABSTRACT:
A metallic stent is coated with a synthetic or biological active or inactive agent that only adheres to the metallic surface of the stent and does not cover slots formed in the stent. In the method, a metallic stent is manufactured in a known manner and is then cleaned to remove surface contaminants and carbon deposits formed from cutting operations and electro-polishing procedures. The stent is then dried in a chamber in which nitrogen gas is purged and then placed in a bath containing a suitable surfactant, such as a long chain alkyl quaternary salt, that removes any residual carbon on the surface of the stent. The stent is then placed in a container filled with the coating agent and the container is placed in an ultrasonic bath. When the bath is activated, the stent swirls in the agent, which agent coats the stent but does not cover the slots of the stent. The stent is removed from the container and dried in a controlled atmosphere.
