Abstract:
1. An electrosurgical apparatus for coagulating tissue, comprising: a first tube having a proximal end and a distal end, the proximal end configured to receive pressurized ionizable gas and the distal end configured to deliver ionized gas towards a treatment area; at least one electrode positioned to selectively ionize the pressurized ionizable gas prior to the pressurized ionizable gas exiting the distal end of the first tube, the electrode adapted to be operatively coupled to an electrical energy source; and a second tube having proximal and distal ends, the second tube configured to selectively evacuate the ionized gas and dislodged tissue material from the treatment area, wherein the distal end of the first tube extends distally beyond the distal end of the second tube and wherein the distal end of the second tube extends distally beyond a distal end of the at least one electrode, wherein the electrosurgical apparatus is configured for simultaneous use for monopolar ablation and to ionize the ionizable gas while the distal end of the second tube extends distally beyond the distal end of the at least one electrode.
