A novel device and method for preventing restenosis and streamlining the angioplasty procedure. The device and method provide a fiberoptic guidewire, or, alternatively, a light-conducting catheter, to decrease the size of the angioplasty device, decrease the overall time of the procedure, and increase the safety of the procedure. The present invention delivers radiation to a sclerotized area after balloon angioplasty treatment to prevent restenosis Radiation delivered via the catheter or fiberoptic guidewire discourages the cell proliferation and cell growth after angioplasty, thereby improving the chances of avoiding restenosis. |
