A therapeutic agent is applied to an internal tissue site of a patient by advancing typically a catheter into the patient to cause a portion of the catheter, typically a catheter balloon, to occupy the internal site. The balloon portion of the catheter carries the therapeutic agent, usually mixed with a controlled release carrier for the agent, typically on an outer surface of the section, to permit release thereof from the catheter balloon at the internal tissue site so that the therapeutic agent is locally applied to the internal tissue site.
