摘要：
An ablation apparatus, comprising: a catheter (14), which has a distal portion (18) for insertion into a body cavity of a living subject and configured to bring the distal portion into contact with a tissue in the cavity of the body； a power generator to generate power at a power output level； an ablation electrode (32) disposed on the distal portion (18), adapted to accept the power of the power generator by means of the catheter (14) and to conduct the energy to the tissue for ablation thereof； a temperature sensor (37) disposed on the distal portion (18) to determine a temperature of the ablation electrode (32)； and a processor (41) configured to iteratively: determine a measured tissue temperature and a measured power level of the energy conducted through the ablation electrode (32)； and control the power output level to minimize the deviation between the measured power level and a target power level, and the deviation between the measured temperature and a target temperature, increasing or decreasing a current level over time, in the that for each iteration, the current level increases or decreases significantly at a function of both the deviation between the measured power level and the target power level and the deviation between the measured temperature and the target temperature.Un aparato de ablación, que comprende: un catéter (14), que tiene una porción distal (18) para la inserción en una cavidad del cuerpo de un sujeto vivo y configurado para poner la porción distal en contacto con un tejido en la cavidad del cuerpo； un generador de potencia para generar energía a un nivel de salida de potencia； un electrodo de ablación (32) dispuesto sobre la porción distal (18), adaptado para aceptar la energía del generador de potencia mediante el catéter (14) y para conducir la energía al tejido para la ablación del mismo； un sensor de temperatura (37) dispuesto sobre la porción distal (18) para determinar una temperatura del electrodo de ablación (32)； y un procesa
