The present invention relates to a drug eluting polymer blend. More particularly, the present invention relates to a medical device with a drug eluting polymer blend incorporated therein wherein the drug elution rate is controlled by cross-linking the polymer blend. Once formed, the polymer blend can be used to create a medical device by itself or in combination with other materials. The drug, or other biologically active agent, can be loaded into the blend by soaking the polymer blend in a solution containing the agent before, during or after formation of the medical device. Alternatively, the drug or agent can be loaded into one of the polymers of the polymer blend before formation of the blend or during formation of the blend. Likewise, the polymer blend can be cross-linked before or after loading the selected drug or biologically active agent. Upon insertion into the body and exposure to the body's fluid, the blend releases the loaded biologically active agent at the desired rate.
