ABSTRACT:
An apparatus for performing controlled tissue ablation in endolaser microsurgery is disclosed, the apparatus including a laser delivery system coupled to a probe capable of transmitting the laser power through a suitable medium such as sapphire. The probe may include a central canal for aspiration and irrigation and delivers a cross-sectionally homogeneous power distribution. The apparatus is designed to control the ablation depth and to limit the zone of thermal damage in the remaining tissue.
