Method and apparatus for treating vessel wall with UV radiation following angioplasty |
摘要 |
Disclosed is an apparatus for use in applying UV light to a blood vessel wall following the performance of a balloon angioplasty procedure. It comprises an elongated optical fiber whose outside diameter permits it to be inserted into the lumen of a guidewire that is used to position the angioplasty balloon at the site of the lesion to be treated. The guidewire is provided with a light port and a suitable reflector is provided for causing UV light transmitted through the optical fiber to be radiated in a radial direction through the light port in the guidewire to thereby irradiate the vessel wall with UV energy that has been found effective in retarding growth of smooth muscle cells.
