Abstract
A method of controlling output power of an electrosurgical generator apparatus that controls a variable output signal to a pair of electrodes includes setting the output power of the generator apparatus to a selected power output level. An impedance is measured across the electrodes when the electrodes are applied to an area of tissue. The output power of the generator apparatus is changed to a boost power output level greater than the selected power output level. The boost power output level corresponds to a calculation based at least in part on the measured impedance. The method further includes applying the output signal to the electrodes at the boost power output level for a first time duration and changing the power output to the selected power output level after the first time duration. An electrosurgical generator apparatus operating in accordance with the method is also described.
