Abstract
A surgical system that applies electrical energy to obtain predetermined surgical effects while improving the control of the application of the energy that is supplied by electrosurgical generators. In one embodiment, a surgical assembly interfaces with and receives power from an electrosurgical generator for executing a first electrosurgical procedure. This surgical assembly may employ a shunt circuit between its power and return lines for providing in effect a voltage limitation and/or to allow a constant power electrosurgical generator to execute an at least substantially constant voltage electrosurgical technique. The electrosurgical assembly may also include a return coupler for directing energy from the patient back to the electrosurgical generator, which in turn may include a dielectric material which interfaces with the patient and which at least initially conveys the return energy via one or more electric fields versus conduction.
