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.

Abstract: An electrosurgical instrument for spinal procedures comprises an elongated tubular member configured to fit within and be extended down a standard sized cannula. The instrument comprises a proximal end including a handle for the surgeon and supplied with fittings for connection to a source of irrigation fluid and a source of suction. The distal end of the instrument has an active end comprising a slightly-flexible curved wire electrode that extends in the plane of the tubular member. Beyond the wire electrode is an exit port for irrigation fluid, and in front of the electrode is a receiving port for suction. The wire electrode is thus flanked in front by the exiting irrigation fluid and behind by the suction, with the result that fluid flow is drawn by the suction across the wire electrode creating pressure forces that direct removed tissue to the suction entrance and its removal from the surgical site.

Abstract: An electrosurgical instrument for use by a surgeon that provides additional features and benefits compared with known designs. The operating mode as well as other operating parameters, especially power level, can be preset by the surgeon before commencing the procedure. Five operating modes are available using a three-button fingerswitch handpiece and a 3-way footswitch, including three unipolar modes and two bipolar modes over a full range of power levels including a new turbo mode for treating heavy bleeders.

Abstract: An electrosurgical instrument that is configured for use in MIS electrosurgical procedures, comprises a handpiece with a separable electrosurgical electrode in the form of a micro-fiber, comprising a long, thin, flexible, insulated wire. The combination is configured to cooperate with the cannula of an endoscope to reach interior tissue. The handpiece is constructed to allow the tip with the micro-fiber active end to be deflected to navigate the fiber end in diverse directions under control of the user, and also allows the deflected position to be releasably clamped with the same hand that manipulates the micro-fiber active end.
