System and method for controlling electrical stimulation and radiofrequency output for use in an electrosurgical procedure
First Claim
1. A method of operating a system (20) for performing an electrosurgical procedure using electrical energy comprising the steps of:
- contacting a first electrode (22) to a target nerve tissue area of a patient for delivery of the electrical energy through the first electrode (22) to the target nerve tissue area, manually operating a screen unit (138) to navigate through a plurality of screen views (28) and to enter inputs to a control unit (24) for controlling the delivery of electrical energy to the first electrode (22), characterized by manually operating a hand controller (30) at the side of the patient and remote from the screen unit (138) to send control signals to the control unit (24) for controlling the delivery of electrical energy to the first electrode (22) whereby inputs to the control unit (24) may be made by either of the multi-function hand controller (30) at the patient'"'"'s side and the screen unit (138) remote from the patient.

Abstract
A system (20) for performing an electrosurgical procedure includes a first electrode (22) for contacting a target nerve tissue area of a patient to deliver electrical energy to the target nerve tissue area. The system (20) is characterized by a multi-function hand controller (30) in communication with a control unit (24) and remote from and corresponding to a screen unit (138) for providing inputs to the control unit (24) in parallel with the screen unit (138) whereby an operator may position the multi-function hand controller (30) at a patient'"'"'s side and enter inputs to said control unit (24) by either of said multi-function hand controller (30) and the screen unit (138). The multi-function hand controller (30) includes a plurality of push-buttons (52) corresponding to the screen unit (138) for entering inputs to the control unit (24). The inputs to the control unit (24) control the electrical energy.
