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.
