Abstract
Disclosed herein are embodiments of an electrosurgical device that include one or more floating electrodes and are specifically adapted to remove, cut, resect, ablate, vaporize, denaturize, drill, coagulate and form lesions in soft tissues, with or without externally supplied liquids, preferably in combination with a resectoscope, particularly in the context of urological, gynecological, laparoscopic, arthroscopic, and ENT procedures. Specific adaptations for urological and gynecological applications, for example kidney stone removal and BPH treatment, are also described.
Claims14
An electrosurgical instrument comprising:
- a. a linear elongate conductive shaft having a proximal end configured for connection to an electrosurgical power source and a distal end having an electrode assembly mounted thereto;
- b. an electrode assembly mounted to the distal end of said elongate shaft that comprises an active electrode and an insulator wherein;
- i. said insulator is formed from a nonconductive dielectric material and is concentrically disposed about the periphery of said active electrode,
- ii. said active electrode is formed from an electrically conductive material, is electrically connected to said conductive shaft, and comprises an exposed ablating surface;
- and
- iii. said exposed ablating surface has a curvilinear profile.
