A tissue ablation system in which an 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.

La présente invention concerne un système d'ablation tissulaire consistant à appliquer au tissu une énergie d'ablation (énergie de fréquence radio, par exemple) et à capter un paramètre physiologique (impédance et/ou température, par exemple) indiquant un changement de la concentration d'humidité du tissu. L'énergie d'ablation est alternativement impulsée et bloquée, afin de générer un train d'impulsions d'énergie. Ladite énergie d'ablation est impulsée si le paramètre physiologique capté dépasse la valeur de seuil indiquant une augmentation de la concentration d'humidité. Cette même énergie est stoppée si le paramètre physiologique capté dépasse une valeur de seuil indiquant une diminution de la concentration d'humidité.
