Laser recannalization of atheromatous vessels using fiber optics

A laser endoscope was devised using optic fibers in order to provide a means of visualization and removal of atheromatous plaques from arteries in cadavers and experimental animals. Atheromatous plaques were satisfactorily lased off in a few seconds, although contraction of lased vessels was observed. A self-focusing fiber was shown to provide laser access to and visualization of the body via a single optic fiber of feasibly less than 0.2 mm diameter.
