ABSTRACT:
Disclosed in one embodiment is a medical device including an expandable metal vascular stent including at least one surface. A coating layer including parylene or a parylene derivative is positioned on the at least one surface. At least one layer comprising a bioactive agent is positioned on the coating layer, wherein the bioactive agent is selected from the group consisting of an immunosuppressive agent, anti-inflammatory agent and an anti-proliferative agent. A porous layer is positioned on the at least one layer including a bioactive agent, wherein upon implantation into a patient, the porous layer controls release of the bioactive agent from the at least one layer including the bioactive agent.
