Abstract

A control system and method for laser angioplasty or laser ablation or welding of tissue in general, in which firing of a laser catheter is correlated with movement of a vessel or other body chamber carrying the laser catheter, whereby the laser is fired only during those times its fiberoptic-delivered beam is aimed at plaque or other target in the vessel or chamber.
