Patent ID: 8333759

Claim:
A method for controlling energy applied to tissue as a function of at least one detected tissue property, comprising the steps of: applying energy to tissue; sensing an electrical conductance of the tissue; detecting at least one bubble field proximate to tissue; and controlling the energy applied to tissue in accordance with a detected slope of a control curve to collapse the detected at least one bubble field, the control curve representative of the sensed electrical conductance of tissue as a function of tissue temperature, the controlling step including: initially adjusting the energy applied to tissue and determining a direction of the change of the detected slope of the control curve; subsequently adjusting the energy applied to tissue in the same direction as the initially adjusting step if the detected slope of the control curve is changing in a first direction and in the opposite direction to the initially adjusting step if the detected slope of the control curve is changing in a second direction; and further adjusting the energy applied to the tissue in the same direction as the initially adjusting step if the detected slope of the control curve is changing in the second direction and in the opposite direction to the initially adjusting step if the detected slope of the control curve is changing in the first direction.
