    Abstract: An electrosurgical generator includes: a power supply configured to output a DC waveform; a power converter coupled to the power supply and configured to generate a radio frequency waveform based on the DC waveform; an active terminal coupled to the power converter and configured to couple to a first electrosurgical instrument and a second electrosurgical instrument; at least one sensor coupled to the power converter and configured to sense at least one property of the radio frequency waveform; and a controller coupled to the power converter. The controller is configured to: determine a first impedance associated with a first electrosurgical instrument and a second impedance associated with a second electrosurgical instrument based on the at least one property of the radio frequency waveform; and adjust at least one parameter of the radio frequency waveform based on the first impedance and the second impedance.

    Abstract: The disclosed systems and methods relate to controlling the application of electrosurgical energy by an electrosurgical instrument. An electrosurgical generator in accordance with the present disclosure includes a processor and a memory storing instructions executable by the processor. The instructions when executed, cause the generator to receive signals from the instrument over time relating to whether tissue is grasped by the instrument, receive an indication to provide an indicated treatment power to the instrument where the indicated treatment power is set by a user, determine based on the signals that tissue is currently grasped and that, for at least a predetermined length of time prior, no tissue had been grasped, and based on the determination, provide a treatment power surge to the instrument for a surge time period. After the surge time period, the generator provides the indicated treatment power to the instrument.

    Abstract: An electrosurgical return electrode is disclosed. The return electrode includes a first and second flexible conductive material layers and a material layer disposed between the first and second conductive material layers. The material layer is transitionable between a solid state and a non-solid state, the material layer is also configured to melt upon an increase in temperature beyond a predetermined threshold, thereby increasing conductivity between the first and second conductive material layer.

    Abstract: An ablation probe is provided. The ablation probe includes a housing that is configured to couple to a microwave energy source. A shaft extends distally from the housing and includes a radiating section at a distal end thereof. A sensor assembly is operably disposed on the housing and includes a pair of sensor contacts. One or more sensors are positioned adjacent the radiating section and extend along the shaft. The sensor(s) have a pair of sensor contact pads that are positioned on the shaft for contact with the pair of sensors such that during transmission of microwave from the radiating section into target tissue at least one electrical parameter is induced into the at least one sensor and detected by the pair of sensor contacts.
