1. A method for heating a treatment region of tissue, said method comprising:

  • introducing a bipolar surgical instrument having first and second jaws with first and second electrode members within the treatment region;

    grasping tissue between the first and second jaws;

    energizing the electrode members at a power level to deliver electrical energy to and heat tissue between the first and second electrode members; and

    increasing the power level at a predetermined rate from an initial level, wherein the initial level and predetermined rate are selected to avoid creating a vapor layer and to permit an impedance increase to occur as a result of complete tissue desiccation.
