    摘要: 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.

    摘要: An apparatus and methods for modifying a surface of a target. The apparatus includes a reaction vessel having a reaction chamber. A cylindrical or spherical grid is positioned within the chamber. An electrode is also positioned within the chamber. A target can be positioned within the chamber and within the grid. A voltage source is operatively associated with the target and with the grid to separately but concurrently provide an independently variable voltage to both the grid and the electrode.
