Abstract

See full text

The invention provides methods, systems and apparatus for electrosurgically treating tissue particularly within the uterus and prostate. In an exemplary method, a surgical instrument comprising an elongate shaft having a proximal end and a distal end, an active electrode near the distal end, and a return electrode is introduced into the uterus. An electrically conductive fluid is then introduced into the uterus to distend the uterus and to form an electrically conductive path between the active electrode and the return electrode. The active electrode is then contacted against tissue within the body cavity. Current is passed between the active electrode and the return electrode while the active electrode is contacting the tissue. The active electrode is provided with a surface area which is selected to produce a power density sufficient to resect or coagulate tissue. The active electrode is then moved along and through the tissue to remove, coagulate or vaporize the tissue.
