Abstract:
Various embodiments are directed to methods for providing an electrosurgical signal to a patient using an electrosurgical system. A method may, for a first application period, apply the electrosurgical signal to first and second electrodes according to a first mode. In the first mode, the electrosurgical signal is limited to a first maximum power when the impedance between the first and second electrodes exceeds a first mode threshold. The method may also, for a second application period after the first application period, apply the electrosurgical signal according to a second mode. In the second mode, the electrosurgical signal is limited to a second mode maximum power when the impedance between the first and second electrodes exceeds a second mode threshold. The second maximum power may be greater than the first maximum power.
