Abstract

Method and apparatus for thermal ablation or coagulation of biological tissue using a scanning laser beam with real-time video monitoring and monitoring of therapeutic treatment parameters, such as temperature prior to or during treatment. In a preferred embodiment, a unique reflective optical delivery system is employed in conjunction with temperature control of the treatment area, and possibly, cryogenic treatment of the treatment area, to eliminate or reduce the need for anesthetics. All therapeutic parameters can be displayed on a video monitor, which is attached to a laser scanner. The reflective optics of the laser scanner can provide precise single-layer vaporization by the laser without thermal injury to the underlying tissue, and the video monitor allows a surgeon to monitor all therapeutic parameters both before and during a treatment procedure. The video monitor also can provide a three-dimensional view of the treatment area. This also can be videotaped for documentation purposes.
