PROBLEM TO BE SOLVED: To provide monopolar and bipolar electrosurgical systems capable of adjusting the impedance of active and return electrodes.SOLUTION: An electrosurgical system 10 includes: at least one electrosurgical electrode having a resistive element and a capacitive element configured in series; and an electrosurgical generator 20 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 the capacitive reactance of the capacitive element in series, thereby adjusting the temperature of the at least one electrosurgical electrode. |
