Abstract
Implantable prosthetic devices are provided for controlled drug delivery, for orthopedic and dental applications. The device may include a prosthetic device body having at least one outer surface area; two or more discrete reservoirs located in spaced apart positions across at least a portion of the outer surface area, the reservoirs formed with an opening at the surface of the device body and extending into the device body; and a release system disposed in the reservoirs which comprises at least one therapeutic or prophylactic agent, wherein following implantation into a patient the therapeutic or prophylactic agent is released in a controlled manner from the reservoirs. The prosthetic device body preferably is a joint prosthesis or part thereof, such as a hip prosthesis, a knee prosthesis, a vertebral or spinal disc prosthesis, or part thereof. Optional reservoir caps may further control release kinetics.
