Publication number: 20070208333Abstract: An electrosurgical generator that can be used, for example, to provide radio-frequency (RF) energy for localized tissue coagulation, cutting, ablation, and to create lesions in nervous tissue. The generator can provide controls for line power, RF power, setting temperature and/or power, for selecting preset temperature and power combinations, and for selecting programmed treatment profiles. The generator can have a display to display the desired probe and tissue temperature, measured probe impedance, actual probe and/or tissue temperature, delivered power, treatment time, mode setting, preset selection, and messages, and indicators for RF Power On, Stimulation On, and Fault Condition. The generator can include the ability to generate low frequency pulses to stimulate nerves and to assist in the proper placement of the electrosurgical probe in the location that is causing pain.Type: ApplicationFiled: May 11, 2007Publication date: September 6, 2007Applicant: SMITH & NEPHEW, INC.Inventors: Andy Uchida, Duane Marion, Ken Woodland, Katherine Knudsen

Publication number: 20050288662Abstract: A method includes recognizing an electrosurgical probe coupled to an electrosurgical generator, selecting a mode of the electrosurgical generator based upon the recognized probe, setting a therapy profile based upon the selected mode, and displaying the therapy profile. The generator can include user inputs for modifying the therapy profile. A computer implemented method for achieving a target temperature includes: a) receiving the target temperature; b) calculating a first set temperature; c) commanding a first output power level until a measured temperature is equal to or greater than the first set temperature; d) calculating an updated set temperature based upon the target temperature; e) commanding a second output power level until the measured temperature is equal to or greater than the updated set temperature; and repeating d and e until the updated set temperature is equal to the target temperature.Type: ApplicationFiled: June 23, 2004Publication date: December 29, 2005Inventors: Andy Uchida, Duane Marion, Ken Woodland, Katherine Knudsen

Publication number: 20050027235Abstract: A surgical device includes an elongated shaft having first and second electrically isolated electrodes coupled to the shaft such that an exposed portion of the second electrode is disposed around only part of a circumference of the elongated shaft, and includes a portion that is spaced proximally from the first electrode. Another surgical device also includes an elongated shaft having first and second electrically isolated electrodes coupled to the shaft, wherein the shaft includes a first side, and exposed surfaces of the first and second electrodes are side-facing toward the first side. Various embodiments of a “cool back” are provided, allowing arthroscopic surgery on a first side of a device without tissue effects on a back side of the device.Type: ApplicationFiled: February 12, 2003Publication date: February 3, 2005Inventors: Katherine Knudsen, Duane Marion, Hugh Sharkey
