摘要
Radiation excision in the range between 248 and 400 nm does not cause the same thermal processes that limit the medical use of conventional lasers. The radiation produced by a laser circumciser (10) is fed to the pathological sites in the body with the aid of optical members (25). In one embodiment, radiation is conveyed by means of an optical fiber waveguide made from fused silica (25) through a hollow catheter (27) which is inserted into the vasculature and finally manages the atherosclerotic lesion in the coronary arteries. In another embodiment, the radiation emitted by the laser is fed to circumciser pathological site in the body by means of an endoscopic device (28). In yet another embodiment, the radiation produced by the laser circumciser is conveyed by means of a focusing lens (29). With the relative absence of destructive thermal effects caused by the laser circumciser on tissues adjacent to the incident beam, and thanks to the possibility of a very localized application, the present invention can significantly improve the clinical use of the laser radiation in surgical procedures.
