Abstract
A method for controlling an electrosurgical electrode of a medical device includes providing an electrosurgical tissue cutting electrode having an arcuate electrode portion; delivering energy from an RF generator to the electrosurgical electrode, said RF generator including an RF amplifier; monitoring an electrical characteristic associated with said electrosurgical electrode; and establishing a desired RF power output and a desired RF duty cycle at said RF generator by adjusting DC input voltage applied to an output stage of said RF amplifier based on said monitoring to effect tissue cutting by the arcuate electrode portion.
