Publication number: 20190223947Abstract: Apparatus, consisting of a probe with a temperature sensor and a transducer in contact with a living subject's tissue. A power supply delivers electrical power to the transducer for tissue ablation. A controller receives a signal from the temperature sensor and in response outputs a tissue temperature. During a first time period the power supply delivers no more than a first target power to the transducer, and reduces the power when a first maximum allowable temperature of the tissue is exceeded. During a transition time period the power supply delivers no more than a second target power, while reducing the delivered power when the first maximum allowable temperature of the tissue is exceeded. During a second time period the power supply delivers no more than the second target power, while reducing the delivered power when a second maximum allowable temperature, less than the first maximum allowable temperature, is exceeded.Type: ApplicationFiled: December 13, 2018Publication date: July 25, 2019Inventors: Assaf Govari, Andres Claudio Altmann, Israel Zilberman

Publication number: 20180263689Abstract: Apparatus, consisting of a probe configured to be inserted into contact with a myocardium, and an electrode attached to the probe. A temperature sensor, incorporated in the probe, is configured to output a temperature signal. A pump irrigates the myocardium, via the probe, with an irrigation fluid at a controllable rate, and a radiofrequency (RF) signal generator applies RF power via the electrode to the myocardium, so as to ablate the myocardium. The apparatus also has processing circuitry that measures a temperature of the probe, based on the temperature signal, while the RF power is applied and, when the measured temperature exceeds a preset target temperature, iteratively reduces the RF power applied by the signal generator and concurrently iteratively varies a rate of irrigation of the irrigation fluid provided by the pump, until the measured temperature is reduced to the preset target temperature.Type: ApplicationFiled: February 13, 2018Publication date: September 20, 2018Inventors: Assaf Govari, Andres Claudio Altmann, Ella Ozeri, Israel Zilberman
