Abstract: A device for generating RF power for an electrosurgical instrument is provided that includes a controller programmed to generate an electrical signal having an oscillating waveform and to modulate the oscillating waveform between a plurality of ON and OFF states to create discrete packets of the oscillating waveform in the plurality of the ON states. The device further has an amplifier in communication with the electrical waveform that amplifies the waveform to create an output signal and an electrosurgical connector configured to receive an electrosurgical instrument and to pass the electrical signal to the electrosurgical instrument.

Abstract: A device for generating RF power for an electrosurgical instrument including a controller programmed to generate an electrical signal having an oscillating waveform and to modulate said oscillating waveform between a plurality of ON and OFF states to create discrete packets of the waveform in the plurality of the ON states. The device further has an amplifier in communication with said electrical waveform that amplifies said waveform to create an output signal and an electrosurgical connector configured to receive an electrosurgical instrument and to pass said electrical signal to said electrosurgical instrument. The controller further modulates the discrete packets to form sub-discrete packets and a second level of sub-discrete packets. A feedback circuit in continuous communication with sensing circuits positioned in the electrosurgical instrument receives electrical power usage data from the operative field and determines adjustments to power supply based on power usage data.

Abstract: An electrosurgical device that has a head having a face. A handle connectable to an RF generator. The device has a plurality of teeth extending from the face. At least one of the plurality of teeth as a first electrical charge. A second of the plurality of teeth has a second electrical charge.
