ABSTRACT:
Methods for heating tissue by delivering radio frequency energy through tissue electrodes comprise controlling energy delivery so that an abrupt increase in impedance between the electrodes and the tissue is observed, typically in the form of an abrupt decrease in power delivered to the electrodes. The power at which the impedance increases and/or the time required to induce such an increase in impedance, are relied on to determine acceptable ranges to achieve a maximum sustainable delivery of radio frequency energy to the tissue consistent with complete, rapid, and uniform heating of the tissue.
