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.

Control console and accessories for RF nerve ablation and methods of operating the same

Electrosurgical systems and methods are provided for RF nerve ablation, wherein a control console is utilized with a passive or active cable accessory connecting to different of electrode attachments, such as monopolar and bipolar self-grounding types. The control console has multiple RF amplifiers that are associated with multiple channels of the control console and that are energized according to control signals non-simultaneously applied by a controller of the control console. The control console stores and processes identification data and usage data relating to cable accessories and electrode attachments that are connected or have been connected to the control console over time. The control console displays a representation of this processed data on a graphical user interface. The control console further provides components and techniques for implementing stimulation and impedance verification/calibration for situations where the stimulation signals or impedance measurement signals are provided by the control console.
