Abstract
The present invention is directed to medical implants that are configured to controllably release therapeutic agent to a target site of a patient and methods of making these implants. Embodiments of the present invention may include a method comprising the steps of providing a tube having a wall with inner and outer surfaces and defining a passageway, forming an opening through the wall of the tube, applying a porous coating layer to at least one of the inner and outer surfaces of the tube, and loading a therapeutic agent solution into the passageway so that therapeutic agent passes through the opening and into the porous coating layer. The method may also include removing portions of the tube to form the implantable medical device, which may be a stent.
