Abstract
A method and apparatus for inhibiting vascular restenosis using a radioactive implantable medical device and a radiosensitizer agent. In one embodiment, the method of the invention includes implanting a medical device at a blood vessel site that has undergone a procedure to open a stenosed region within a blood vessel. The medical device contains a radioisotope to emit a radioactivity to a tissue mass at the blood vessel site. The method further includes delivering a radiosensitizer agent to the tissue mass at the blood vessel site. The radiosensitizer agent increases a therapeutic response of the tissue mass to the radioactivity emitted by the radioisotope.
