ABSTRACT:
An electrosurgical system for applying electrical energy to a tissue structure within a patient's body comprises an electrosurgical probe and one or more high frequency power supplies. The probe comprises a shaft having an electrode array of isolated electrode terminals at its distal end. The terminals are each coupled to one of a multiplicity of current limiting elements, such as inductors. The inductors, together with the inherent capacitance of the load, form a series resonant output circuit having a resonant frequency greater than the operating frequency of the power supply.
