| 20090270849 | Electrosurgical Device and Method - The present invention relates to the field of electrosurgery, and more particularly to a system that produces an ionized gas flows that are configured to function as an electrode arrangement. A working end of an elongated member can use spaced apart conductive gas flows to coagulate or ablate tissue interstitially, intraluminally or topically. | 10-29-2009 |
| 20100106152 | ENDOMETRIAL ABLATION METHOD - 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. | 04-29-2010 |

| 20110112523 | SYSTEMS, METHODS AND DEVICES FOR ENDOMETRIAL ABLATION UTILIZING RADIO FREQUENCY - Methods, systems and devices for endometrial ablation. In accordance with a method, a working end of an RF ablation device is positioned in a patient uterus to contact endometrial tissue, the working end comprising a dielectric. Radiofrequency energy is applied for a first interval of time at constant power, the power being sufficient to capacitively couple current across the dielectric to the contacted endometrial tissue. A voltage parameter measured within the first interval, and radiofrequency energy is applied at a constant voltage over a second, treatment interval to ablate endometrial tissue, the constant voltage being related to the recorded voltage. | 05-12-2011 |
