Abstract: Systems and methods to confirm safe delivery of treatment energy to a patient by identifying a presence of a fault in an energy delivery pathway and identifying a location of the fault within the device. The system includes a processing unit configured to calculate blood impedances external to the device based on known impedance characteristics of the device, and then to calculate impedances within the device during energy delivery based on the calculated blood impedances. The processing unit prevents the delivery of energy in an energy delivery pathway that is determined to be compromised. The processing unit is also configured to compare times for two different frequencies to travel a predetermined distance, the difference in the times corresponding to a location of a fault within the energy delivery pathway.

Abstract: An isolating circuit for electrosurgical generator arranged to produce radiofrequency (RF) energy and microwave energy for treating biological tissue. The generator has an RF channel and a microwave channel which are combined at signal combiner to enable the RF energy and microwave energy to be delivered into tissue along a common feed path. The isolating circuit comprises a tunable waveguide isolator at a junction between the microwave channel and signal combiner, and can include a capacitive structure between a ground conductor of the signal combiner and a conductive input section of the waveguide isolator to inhibit coupling of the RF energy and leakage of the microwave energy. The isolating circuit can combine into a single tunable unit all the necessary components to isolate the microwave and RF channels from one another whilst providing a high withstanding voltage.

Abstract: A non-transitory computer-readable storage medium is presented including a power supply module configured to output power, a first energy module configured to receive the power and convert the power into a first waveform having a first phase, and to deliver the power in a first energy mode, and a second energy module configured to receive the power and convert the power into a second waveform having a second phase, and to deliver the power in a second energy mode. A host controller module is configured to control a type and a number of energy modalities provided by the generator platform and a comparator compares the first phase of the first waveform with the second phase of the second waveform in one or more of a plurality of sub-periods. An adjustment module adjusts a relative phase between the first and second waveforms based on results obtained from the comparator.

Abstract: A surgical instrument comprises a shaft assembly comprising a shaft and an end effector coupled to a distal end of the shaft; a handle assembly coupled to a proximal end of the shaft; a battery assembly coupled to the handle assembly; a radio frequency (RF) energy output powered by the battery assembly and configured to apply RF energy to a tissue; an ultrasonic energy output powered by the battery assembly and configured to apply ultrasonic energy to the tissue; and a controller configured to, based at least in part on a measured tissue characteristic, start application of RF energy by the RF energy output or application of ultrasonic energy by the ultrasonic energy output at a first time.
