摘要： An electrosurgical system for radiofrequency ablation. An electrosurgical console includes a processor configured to determine impedance threshold values based on an initial tissue impedance value. The impedance threshold values may vary based on an elapsed time-based characteristic. A temperature set point is reduced based on the occurrence of the impedance event in which a tissue impedance value exceeds a threshold value. The reduced temperature set point may be fixed. The controller is configured to control the delivery of the RF energy drive the tissue temperature to the temperature set point(s). The temperature set point may not be reduced if the impedance event occurs during a ramp period, and an alert may be displayed. Secondary impedance threshold values may be utilized, and slower ramp periods may be provided for later in the ablation procedure. Methods of performing the ablation procedure with the electrosurgical system are also disclosed.

摘要： Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power-a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

摘要： The present invention resides in one aspect in a device for monitoring luminal esophageal temperatures in a patient. The device includes a probe adapted to be inserted into an esophagus of the patient. The probe extends between a proximal end and a distal end. A first temperature sensor and a second temperature sensor are coupled to the probe. An electrode is also coupled to the probe. The second temperature sensor is displaced from the first temperature sensor along a longitudinal axis of the probe. A controller processes information received by the electrodes and the temperature sensors. The controller generates a live and continuously updating three dimensional anatomic map and three dimensional thermal map of the esophagus based at least in part on the information received from the temperature sensors and the electrodes. The thermal map and the anatomic map are displayed on a video monitor.
