摘要： 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.

摘要： An electrosurgical working end and method for sealing and transecting tissue. An exemplary working end provides curved jaw members that are positioned on opposing sides of the targeted anatomic structure. The working end carries a slidable extension member having flange portions with inner surfaces that slide over the jaw members to clamp tissue therebetween. The working end carries an independent slidable cutting member that is flexible to follow the curved axis of the jaws. The electrosurgical surfaces of the jaws include partially-resistive bodies for carrying a current or load which modulates ohmic heating in the engaged tissue to prevent charring and desiccation of tissue to create a high strength thermal seal.

摘要： Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate.

摘要： The present invention relates to the field of electrosurgery, and more particularly to a system that produces a focused plasma for tissue ablation. The system includes a probe and a remote source of a conductive liquid media for providing a flow through the probe that functions as an electrode. A pressurized flow of the liquid media passes through a first larger diameter flow channel in the probe to then increases in velocity as it passes through a smaller diameter flow restriction channel in a working end surface. The flow restriction of the liquid electrode through the flow restriction channel when coupled with high frequency voltage causes instantaneous ignition of a plasma within media flow media within the flow restriction channel. The working end surface thus carries a plasma that when proximate to tissue will cause a controlled, focused ablation.
摘要翻译：本发明涉及电外科领域，更具体地涉及产生用于组织消融的聚焦等离子体的系统。该系统包括用于提供作为电极起作用的通过探针的流动的导电液体介质的探针和远程源。液体介质的加压流通过探针中的第一较大直径的流动通道，然后当其通过工作端面中的较小直径的流动限制通道时，速度增加。当与高频电压耦合时，通过流动限制通道的液体电极的流动限制导致流量限制通道内介质流媒体内的等离子体的瞬时点燃。因此，工作端面承载等离子体，当等离子体靠近组织时，将引起受控的聚焦消融。

摘要： Various embodiments provide compositions that exhibit positive temperature coefficient of resistance (PTCR) properties for use in thermal interactions with tissue—including thermal sensing and I2R current-limiting interactions. Embodiments also provide tissue-engaging surfaces having PTCR materials that provide very fast switching times between low resistance and high, current-limiting resistance. One embodiment provides a matrix for an electrosurgical energy delivery surface comprising a PTCR material and a heat exchange material disposed within an interior of the matrix. The PTCR material has a substantially conductive state and a substantially non-conductive state. The heat exchange material has a structure configured to have an omni-directional thermal diffusivity for exchanging heat with the PTCR material to cause rapid switching of the PTCR material between the conductive state and non-conductive state. Preferably, the structure comprises a graphite foam having an open cell configuration. The matrix can be carried by tissue contacting surfaces of various electrosurgical devices.
