Abstract:
A gas-enhanced electrosurgical method and apparatus for coagulating tissue. The apparatus includes a first tube with a proximal end and a distal end. The proximal end of the first tube is configured to receive pressurized ionizable gas. The distal end of the first tube is configured to deliver ionized gas towards a treatment area. The apparatus also includes at least one electrode positioned to selectively ionize the pressurized ionizable gas before the pressurized ionizable gas exits the distal end of the first tube. The electrode is adapted to operatively couple to an electrical energy source. The apparatus also includes a second tube with proximal and distal ends. The second tube is configured to selectively evacuate the ionized gas and dislodged tissue material from the treatment area.
