Abstract: A planar transformer power supply for an electrosurgical device to minimize stray capacitance comprising a step down/step-up isolation transformer and circuitry to limit the effects of a short circuit in the output of the planar transformer power supply on the input to the planar transformer power supply to enhance power capacity at a low load impedance as low as from about 5 ohms to about 10 ohms and to operate at resonance at the output of the planar transformer power supply.

Abstract: An electrosurgical device to generate a plasma stream for performing electrosurgery on a surgical site on a patient comprising an electrosurgical generator coupled to a electrical power source to supply power to the electrosurgical device and a plasma generator including an electrode operatively coupled to the electrosurgical generator to receive electrical energy therefrom and concentrically disposed within an inner noble gas conduit to form a plasma channel coupled to a noble gas source to feed noble gas to the inner noble gas conduct, an intermediate electronegative gas conduit disposed in surrounding coaxial relation relative to the noble gas conduit to cooperatively form an electronegative gas channel therebetween coupled to a gas source to feed electronegative gas to the electronegative gas channel and an outer aspiration conduit disposed in surrounding coaxial relation relative to the intermediate electronegative gas conduit to cooperatively form an aspiration channel therebetween coupled to a negative

Abstract: A tray to protect the loop of a loop electrode during sterilization, shipping, handling and storage wherein the tray comprises a wall extending upwardly from a bottom wall to cooperatively form a cavity to receive the loop and distal end portion of the electrode shaft therein, a peripheral flange extending outwardly from the lower portion of the wall and an electrode limit to limit movement of the loop electrode within the cavity to limit lateral and longitudinal movement of the loop electrode relative to the tray to maintain the loop in spaced relationship relative thereto.

Abstract: An electrosurgical instrument comprising a work implement having a medically acceptable working edge with a plurality of layers of different compositions including an inner primer layer with an electrically conductive polymer with a coating thickness of about 0.3 mil, an intermediate layer having a coating thickness of about 0.1 mil and an outer protective layer having a low coefficient of friction with a thickness of about 0.3 mil to reduce the adhesion of charred tissue during surgical procedures involving cauterization or cutting of tissue utilizing high frequency electrical energy as the source of power.
