    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.

    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. When the instructions are executed, they 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 predetermine 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, where the treatment power surge is greater than the indicated treatment power. After the surge time period, the generator provides the indicated treatment power to the instrument.

    Abstract: The present disclosure includes an electrosurgical generator that controls treatment energy to be provided in a coagulation mode, where the treatment energy has an adjustable voltage ramp rate which can be set to a ramp rate in a range of voltage ramp rates. The generator receives signals from an instrument over time relating to load impedance. When the load impedance is above a threshold, the generator sets the adjustable voltage ramp rate to a ramp rate in the range of voltage ramp rates, and decreases, at the adjustable voltage ramp rate, a voltage of the treatment energy. When the load impedance is below the threshold, the generator sets the adjustable voltage ramp rate to a ramp rate in the range of voltage ramp rates, and increases, at the adjustable voltage ramp rate, the voltage of the treatment energy.

    Abstract: The disclosed systems and methods relate to controlling the application of electrosurgical energy by an electrosurgical instrument to minimizing arcing and subsequent wear of electrosurgical instruments. An electrosurgical generator in accordance with the present disclosure includes a processor and a memory storing instructions executable by the processor. When the instructions are executed, they cause the generator to provide an indicated treatment energy to the instrument, where the indicated treatment energy is set by a user and having a corresponding current limit, receive signals from the instrument over time relating to a load impedance between the active electrode and the return electrode of the instrument, determine based on the signals that the active electrode and the return electrode are currently shorted together, and prior to the short, the instrument was grasping tissue between the active electrode and the return electrode, and based on the determination, reduce a current limit of treatment energy being provided to the instrument to below the corresponding current limit.
