Abstract
Systems and methods using an electrode able to transmit heating or ablation energy into tissue include first and second sensing elements associated with the electrode for measuring first and second temperatures. The electrode also includes a heating element in thermal conductive contact with the electrode for heating the electrode. The systems and methods sequentially activate the heating element and sense temperatures without transmitting tissue heating or ablation energy, and then transmit heating or ablation energy and sense temperatures without activating the heating element, to derive from the sensed temperatures a prediction of maximum tissue temperature.
