Abstract
An implantable medical device for releasing therapeutic agent having a medical device body and a plurality of reservoir-defining structures disposed on a surface of the body. A reservoir can be defined by the reservoir-defining structures and therapeutic agent may be located in the reservoir. A cover may extend over the reservoir so that the therapeutic agent is released from the reservoir when the medical device implanted. Methods for making the medical device may also include providing a medical device body, positioning a plurality of reservoir-defining structures on a surface of the body to form a reservoir, loading therapeutic agent into the reservoir, and covering the reservoir so that the therapeutic agent may release when the medical device is implanted. Alternatively, the reservoir may be covered with a cover and an opening formed in the cover so that the therapeutic agent may release when the medical device is implanted.
