Electrosurgical mode conversion system
First Claim
1. An electrosurgical assembly which interfaces with a generator for executing a first electrosurgical procedure and which comprises:
- an output assembly which is at least operatively interconnectable with said generator;
an active electrosurgical element which is operatively interconnected with said output assembly and which interacts with a first portion of a patient during said first electrosurgical procedure;
a return path element which interacts with a second portion of said patient during said first electrosurgical procedure and which is mechanically interconnected with said active electrosurgical element to define a bipolar configuration, wherein said first and second portions are different, and wherein said return path element comprises a first dielectric component which interfaces with said patient; and
a return assembly which is operatively interconnected with said return path element and further which is at least operatively interconnectable with said generator,wherein said return path element further comprises a first return conductor which interfaces with said first dielectric component in such a manner that energy is returned to said generator first through said first dielectric component and then to said first return conductor,wherein said first dielectric component is defined by a first tube,wherein said first return conductor is defined by a second tube, andwherein said first and second tubes are disposed in end-to-end relation.

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.
