Abstract

A first member of a clamping device is positioned at a first side of a portion of human tissue. The first member has a plurality of electrodes disposed thereupon. A second member of the clamping device is positioned at a second and opposite side of the human tissue. The second member has a plurality of thermocouples disposed thereupon. The first member is aligned with the second member such that each of the thermocouples on the second member is positioned across the tissue from and in the general vicinity of at least one electrode for recording the temperature of the tissue adjacent to the at least one electrode. RF energy is supplied to the plurality of electrodes and a return electrical path is provided from the plurality thermocouples. The path is electrically isolated from the RF energy supplied to the plurality of electrodes and terminates at an ablation monitoring and RF energy delivery system. The RF energy delivery system responsively adjusts an amount of RF energy delivered to the plurality of electrodes based upon the temperature.
