Patent attributes
An electrosurgical probe configured for cutting or coagulating tissue, and an electrosurgical procedure that employs the electrosurgical probe. The probe includes first and second conductors disposed in a sheath, and first and second electrodes electrically insulated from the sheath and protruding from its distal end. The first electrode is electrically connected to the first conductor to define an active pole of a radio frequency circuit, and configured to perform cutting or coagulation of tissue when the radio frequency current flows to the first electrode. The second electrode is electrically connected to the second conductor, and configured to define a focused ground point in close proximity to the active pole defined by the first electrode so as to complete the radio frequency circuit with the first electrode when a conductive fluid surrounds the first and second electrodes and the radio frequency current flows to the first electrode.
