Abstract
Tissue ablation systems and methods are provided. Ablation energy (e.g., radio frequency energy) is delivered to the tissue and a physiological parameter (e.g., impedance and/or temperature) indicative of a change in moisture concentration of the tissue is sensed. The ablation energy is alternately pulsed on and off to generate an energy pulse train, with the ablation energy being pulsed on if the sensed physiological parameter crosses a threshold value indicative of an increase in the moisture concentration, and being pulsed off if the sensed physiological parameter crosses a threshold value indicative of a decrease in the moisture concentration.
