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.

Abstract: Systems and methods for endometrial ablation. The systems include a handle and elongated introducer sleeve extending to an expandable working end having a fluid-tight interior chamber. A thin dielectric wall surrounds at least a portion of the interior chamber and has an external surface for contacting endometrial tissue. The thin dielectric wall surrounds a collapsible-expandable frame and receives an electrically non-conductive gas. First and second polarity electrodes are exposed to the interior and exterior of the chamber, respectively. A radiofrequency power source operatively connects to the electrode arrangement to apply a radiofrequency voltage across the first and second electrodes, wherein the voltage is sufficient to initiate ionization of the neutral gas into a conductive plasma within the interior chamber, and to capacitively couple the current in the plasma across the thin dielectric wall to ablate endometrial tissue engaged by the external surface of the dielectric structure.
