Abstract
Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. In addition, various polymer combinations as well as other therapeutic agents may be utilized to control the elution rates of the therapeutic drugs, agents and/or compounds from the implantable medical devices.
