Abstract
An electrosurgical system includes a radiofrequency (RF) generator having a controller configured to detect an occurrence of a vaporization point of target tissue and a vaporization duration between commencement of delivery of the RF energy and the occurrence of the vaporization point. The controller can apply the vaporization duration to adjust a parameter during subsequent electrode activation, such as RF power level, an electrode activation sequence, a distance between activated electrodes, and a number of activated electrodes. The controller can apply the vaporization duration to determine if whether a predetermined depth of effect has been reached for use in subsequent parameter adjustments.
