Abstract
Electrosurgical systems and methods are provided for RF nerve ablation, wherein a control console has multiple RF amplifiers associated with multiple channels, and multiple DC power supplies each dedicated to a corresponding one of the RF amplifiers. Each of a plurality of power supply relays are coupled between one of the DC power supplies and the dedicated corresponding one of the RF amplifiers. A controller is configured to apply switching signals to control each of the power supply relays to selectively switch on and off connections between the DC power supplies and the dedicated corresponding RF amplifiers. The controller may apply control signals to each RF amplifier sequentially, one at a time, to deliver energy separately and independently to each of the corresponding channels. The controller may be configured to apply the switching signals to self-grounding relays to selectively switch on and off connections between the channels and return relays.
