Patent number: 7175621Abstract: A surgical system that applies electrical energy to obtain predetermined surgical effects while improving the control of the application of the energy that is supplied by electrosurgical generators. In one embodiment, a surgical assembly interfaces with and receives power from an electrosurgical generator for executing a first electrosurgical procedure. This surgical assembly may employ a shunt circuit between its power and return lines for providing in effect a voltage limitation and/or to allow a constant power electrosurgical generator to execute an at least substantially constant voltage electrosurgical technique. The electrosurgical assembly may also include a return coupler for directing energy from the patient back to the electrosurgical generator, which in turn may include a dielectric material which interfaces with the patient and which at least initially conveys the return energy via one or more electric fields versus conduction.Type: GrantFiled: November 25, 2003Date of Patent: February 13, 2007Assignee: Surginetics, LLCInventors: Warren P. Heim, James L. Brassell, Michael D. Olichney

Publication number: 20040030330Abstract: A surgical device includes a return electrode, an active electrode, and an insulating region adjacent to the active electrode. A rasping surface is provided by either the active electrode or the insulating region. Another surgical device includes an adapter configured to couple to a generator and to convert monopolar output from the generator into bipolar output. A method of applying electricity to tissue includes bringing a surgical device into close proximity with tissue and applying electricity to the tissue using the surgical device.Type: ApplicationFiled: August 22, 2003Publication date: February 12, 2004Inventors: James L.

Publication number: 20020024036Abstract: A valve (1) suitable for use on an indwelling catheter is disclosed. Broadly the valve (1) comprises a valve housing (2) having an elongate valve insert (3) disposed therein. The housing (2) has an inlet (4) at one end thereof and an outlet (5) at an opposed end thereof and defines a longitudinal passage (7) extending from the inlet (4) to the outlet (5). The valve insert (3) includes a cannula (25) having an inlet (26) towards one end (27) thereof and an outlet (28) towards an opposed end (29) thereof. The inlet end (27) of the cannula (25) terminates in a sharp point. The outlet end (29) by contrast is rounded and the actual outlet (28) is spaced axially inwardly from the end (29). The valve insert (3) further includes a seal (40) comprising an annular body (41) of resilient material defining an opening (42) therein through which the outlet end (29) of the cannula (25) projects. The seal (40) has an axial end surface which sealingly engages a seat (19) defined by the housing (2).Type: ApplicationFiled: August 23, 2001Publication date: February 28, 2002Inventors: John D. Rohrbough, Michael D. Olichney

Patent number: 6241723Abstract: An electrosurgical system is disclosed that applies electrical energy to obtain a predetermined surgical effect, while also reducing eschar deposits on a working surface of an electrosurgical instrument, producing an eschar deposit which is easily removed from the working surface and/or facilitating removal of eschar deposits during a cleaning procedure. Such benefits may be realized by providing a negative bias on the working surface relative to a return path to source during electrosurgical procedures and/or during a cleaning procedure which may include contacting the working surface with an electrically conductive liquid. To reduce smoke generation at a surgical site, the electrosurgical instrument may comprise a metal body having an outer insulating layer to reduce thermal/electrical discharge from non-functional portions of the instrument. An insulating layer having a thermal conductance of about 1.2 W/cm2° K and a dielectric withstand strength of at least about 50 volts may be employed.Type: GrantFiled: April 21, 1999Date of Patent: June 5, 2001Assignee: Team Medical LLCInventors: Warren P. Heim, Michael D. Olichney, James L. Brassell

Patent number: 5421829Abstract: An ultrasonic oscillator drives a tool at a set frequency. An amplitude control runs the oscillator to set the vibration level. A frequency regulator joins the amplitude and the oscillator. A control feedback loop, in the frequency regulator, keeps handpiece linear dynamics. An operational transconductance amplifier, in the oscillator, governs gain of the loop. A circuit connects to the control to retard the rate of current application over time to the amplifier. The circuit has switching to either retard the rate or reset for start up. The amplifier is a current output device with current directly proportional to the bias current and input voltage with bias as gain change for the loop. The circuit limits the bias to the amplifier to modify frequency response and output current. A capacitor delays application of the bias to the amplifier. Replaceable tools of various lengths or shapes positioned along an axis vibrate for surgery at the frequency and a wave length.Type: GrantFiled: May 13, 1994Date of Patent: June 6, 1995Assignee: Valleylab Inc.Inventors: Michael D.

Patent number: 5082014Abstract: An apparatus and method are disclosed for effecting compounding of parenteral admixture solutions, and recirculation with the admixture solution being formed. The apparatus includes a pump cassette configured for operative association with a pump driver, whereby one or more selected source solutions are delivered through the pump cassette to an associated admixture container. After pumping of each source solution, the present method contemplates that the admixture being formed is recirculated through the pump cassette, thereby diluting any source solution in the cassette and associated tubing. In this manner, the possible mixture of incompatible source solutions, resulting in formation of precipitate, is desirably avoided.Type: GrantFiled: December 1, 1989Date of Patent: January 21, 1992Assignee: Abbott LaboratoriesInventor: Michael D.
