Abstract:

An electrosurgical device and methods of use thereof. In an embodiment, the device comprises a multipurpose electrosurgical device comprising a handle, a shaft distal to the handle, a first, retractable electrode and a second non-retractable electrode, the electrodes adjacent a distal end of the shaft. The device may be selectively configured for use in a bipolar and a monopolar mode and may provide for selective extension and retraction of the retractable electrode. The retractable electrode may be selectively extended and retracted into a cavity within the shaft. When the retractable electrode is in a retracted position, the device may be configured for use in a monopolar mode. When the retractable electrode is in an extended or fully extended position, the device may be configured for use in a bipolar mode.
