Abstract
Laser thermotherapy apparatus including a laser splitter which branches laser energy from a laser source to laser guides or optical fibers, each guide having an emitting end. First and second switches are positioned, respectively, before the splitter and in the individual laser guides. Temperature sensors are provided to sample the temperature of living tissue located adjacent each guide emitting end. A controller turns the respective switches on and off in response to the sensed temperature thereby to maintain a predetermined, selectable tissue temperature.
