Abstract
A method for controlling an electrosurgical generator configured to apply energy to tissue as a function of a detected tissue property is contemplated by the present disclosure. The method includes the step of applying energy to the tissue in a first state, wherein the first state is configured to adjust the power output of the generator to continuously achieve peak tissue conductance as a function of the detected tissue property. The method also includes the step of monitoring a trend of the at least one detected tissue property indicative of a bubble field formation during a second state, which is running concurrently with the first state. The second state is configured to interrupt the bubble field to collapse the bubble field based on the trend of the at least one detected tissue property.
