Coated implantable medical device

An implantable medical device, comprising:

• a stent adapted for introduction into a patient, the stent having at least one surface;
• at least one coating layer comprising a bioabsorbable polymer posited in contact with the at least one surface of the stent;
• at least one layer comprising an immunosuppressive agent posited over the at least one coating layer;
• at least one porous layer posited over the at least one layer comprising the immunosuppressive agent, wherein the least one porous layer comprises open pores upon deposition.

A medical device, comprising:

• an expandable metal vascular stent comprising at least one metal surface;
• a coating layer comprising parylene or a parylene derivative that is positioned directly against the at least one metal surface;
• at least one layer comprising a bioactive agent selected from the group consisting of an immunosuppressive agent, anti-inflammatory agent and an anti-proliferative agent;
• wherein the at least one layer comprising the bioactive agent is positioned on the coating layer;
• a porous layer positioned on the at least one layer comprising the bioactive agent;
• and
• wherein upon implantation into a patient, the porous layer controls release of the bioactive agent from the at least one layer comprising the bioactive agent.
