HARD TISSUE ABLATION SYSTEM

摘要

An electrosurgical system or method for treating hard or soft tissues in the body comprises a shaft (36), a first distal end section (58), an active electrode (60) associated with the distal end section, a first fluid supply (62) adapted to deliver a first electrically conductive fluid (62A) to the target site, and a second fluid supply (64) adapted to deliver a second electrically conductive fluid (64A) to the active electrode. The system is adapted to treat a wide variety of hard tissues such as, for example, bones, calcified structures, calcified deposits, teeth, plaque, kidney-stones, gall-stones, and other types of tissue by generating plasma in the vicinity of the active electrode, and applying the plasma to the tissue or structures.
