The method terminates the generation of subsequent RF energy pulses upon a determination that the electrical transient is absent or that a minimum output voltage has been reached.

摘要： A system for controlling temperature of a fluid used during treatment of biological tissue includes a fluid temperature control apparatus. The apparatus includes at least one heat transfer device and a solution bag and/or a heat transfer membrane. The solution bag and/or the heat transfer membrane reside in thermal communication with the heat transfer device. When the solution bag and/or the heat transfer membrane is fluidically coupled to an electrosurgical device, fluid is supplied to the electrosurgical device at a controlled temperature during a surgical procedure utilizing the electrosurgical device to enable more efficient treatment of the biological tissue. A corresponding method includes fluidically coupling the fluid temperature control apparatus to the electrosurgical device and supplying fluid at a controlled temperature during a surgical procedure utilizing the electrosurgical device to enable more efficient treatment of the biological tissue.

摘要： A bipolar electrosurgical instrument has opposable seal surfaces on its jaws for grasping and sealing vessels and vascular tissue. Inner and outer instrument members allow arcuate motion of the seal surfaces. An open lockbox provides a pivot with lateral support to maintain alignment of the lateral surfaces. Ratchets on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion on each member is tuned to provide an appropriate spring force to hold the seal surfaces together. During surgery, the instrument can be used to grasp and clamp vascular tissue and apply bipolar electrosurgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.

摘要： The present disclosure relates to systems and devices for positioning and placing multiple electrodes in a target surgical site. A guide block is disclosed which introduces electrodes into target tissue and includes an elongated, generally rectilinear bar having a plurality of slots defined therethrough. Each of the slots is configured to selectively receive and retain a corresponding electrode therein. The rectilinear bar is malleable and selectively bendable from a substantially linear configuration to a substantially curved configuration to facilitate positioning the guide block relative to target tissue.
