1990019-A2 is referenced by 44 patents.

An electrosurgical system is disclosed. The electrosurgical system includes at least one electrosurgical electrode having a resistive element and a capacitive element configured in series. The electrosurgical system also including an electrosurgical generator configured to generate electrosurgical energy having a first frequency which generates a first impedance in the at least one electrode due to capacitive reactance of the capacitive element in series. The generator is further configured to adjust the first frequency to at least one other frequency to generate a different impedance in the at least one electrode due to capacitive reactance of the capacitive element in series, thereby adjusting the temperature of at least one electrosurgical electrode.
