Patent number: 9119623Abstract: An electrosurgical generator apparatus controls a variable output signal to electrodes. The generator apparatus operates in a cut mode, a coagulation mode or a stimulate mode. The generator apparatus comprises a DC power supply that provides regulated low voltage and high voltage outputs and a radio frequency (RF) waveform generator circuit that provides pulse duration modulation (PDM) of a carrier signal. The carrier signal directly affects the variable output signal to the electrodes. A control circuit controls a variable output signal to electrodes used in electrosurgical procedures. The control circuit comprises a DC power supply circuit that provides regulated low voltage and high voltage outputs and an RF waveform generator circuit that provides pulse duration modulation of a carrier signal. The carrier signal directly affects the variable output signal to the electrodes.Type: GrantFiled: November 29, 2010Date of Patent: September 1, 2015Assignee: Synergetics USA, Inc.Inventors: Jerry L. Malis, Leonard I. Malis, Robert R. Acorcey, David L. Solt, Anthony John Groch

Publication number: 20080004619Abstract: An electrosurgical bipolar instrument includes an instrument housing having a distal end, a proximal end and an elongated body therebetween. The electrosurgical bipolar instrument includes a pair of radio frequency (RF) electrodes disposed at the distal end of the instrument housing and a control circuit mounted within the instrument housing. The control circuit has a first cut/coagulate mode pad, a common pad and a first cut/coagulate mode push button configured to electrically couple the first cut/coagulate mode pad to the common pad when actuated. The electrosurgical bipolar instrument further includes a plug coupled to the proximal end of the instrument housing having first and second RF contacts electrically coupled to the pair of RF electrodes. The plug has a first cut/coagulate mode contact and a first common contact electrically isolated from the first and second RF contacts and the pair of RF electrodes.Type: ApplicationFiled: June 28, 2007Publication date: January 3, 2008Applicant: SYNERGETICS USA, INC.Inventors: Jerry L.

Patent number: 5318563Abstract: An electrosurgical bipolar RF generator apparatus includes a bipolar electrode. An aperiodic sequence of uniform width bursts of a high frequency signal are electronically synthesized. Substantially identical decaying amplitude envelopes are impressed on the bursts of the high frequency signal. Each of the envelopes has a predetermined rate of change from a preselected initial amplitude. The impressed bursts of the high frequency signal are applied to the electrode. The electrical apparatus operates in a cut mode or a coagulation mode. The apparatus includes a power supply for providing a variable DC voltage, a short circuit detect circuit for detecting a short circuit at the bipolar electrode, and an open circuit detector for detecting an open circuit at the bipolar electrode.Type: GrantFiled: June 4, 1992Date of Patent: June 7, 1994Assignee: Valley Forge Scientific CorporationInventors: Jerry L.

Patent number: 4590934Abstract: A bipolar cutter/coagulator produces a coagulating waveform comprising an aperiodic sequence of damped RF bursts. The inter-burst spacing is pseudo-random, and the intra-burst RF frequency is swept between preset limits. The burst envelopes are uniform, always starting at the same preselected amplitude.Type: GrantFiled: May 18, 1983Date of Patent: May 27, 1986Assignees: Jerry L. Malis, Leonard I.
