Abstract: A device is provided for use with a medical implant for delivering an agent to a designated site of action in a body of a patient. The agent-delivery device comprises a body member having an inner surface and a projection on the inner surface of the body member. An agent-delivery medium is associated with the body member. The agent-delivery medium includes a therapeutic agent for treating the body of the patient. The body member is adapted to be secured to the medical implant such that the projection operatively engages the medical implant for spacing the inner surface of the body member from the implant, and the agent-delivery medium is configured to release the therapeutic agent after implantation in the body of the patient. In alternative embodiments, the agent-delivery device comprises a first body member having an inner surface and a second body member having an inner surface.
