Patent number: 7947041Abstract: A bipolar electrosurgical instrument for clamping, grasping, manipulating, and sealing tissue includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof. The handle being operable to effect movement of the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The bipolar instrument is connectable to a source of electrical energy having a first electrical potential connected to one of the jaw members and a second electrical potential connected to the other of the jaw members such that the jaw members are capable of selectively conducting energy though tissue held therebetween to effect a seal. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.Type: GrantFiled: August 19, 2009Date of Patent: May 24, 2011Assignee: Covidien AGInventors: Philip M. Tetzlaff, Carolyn Mihaichuk, Duane E. Kerr, David A. Schechter, Jonathon Sherman, Theodore Richardson, Gregory Drach

Patent number: 7469462Abstract: An electronic control pedal assembly includes a fixed support structure and a pedal arm. The pedal arm has a lower end carrying a pedal and is pivotable relative to the support structure. A potentiometer is at least partly carried by the fixed support and operable to generate an electric control signal that varies in magnitude in proportion to the extent of movement of the pedal arm relative to the fixed support structure. The potentiometer has at least one resistive track trimmed after assembly of the potentiometer to the fixed support so that the potentiometer provides a first fixed electric control signal at a idle position of the pedal arm and the potentiometer has at least one resistive track trimmed after assembly of the potentiometer to the fixed support so that the potentiometer provides a second fixed electric control signal at a full throttle position of the pedal arm.Type: GrantFiled: February 20, 2005Date of Patent: December 30, 2008Assignee: Dura Global Technologies, Inc.Inventors: Theodore Richardson, Kirk Nielsen, Richard Boatright, Jeffrey Gibson

Patent number: 6673087Abstract: Surgical scissors include a pair of scissor blades mounted at a distal end of an elongated flexible body and a housing attached to the proximal end of the elongated body. An actuator is coupled with mechanical advantage to the scissor blades for manually controlling shearing movement of the blades in response to finger movement on the actuator back and forth along the housing. Electrical conductors are provided through body and housing from a connector to the scissor blades. The housing is configured to be assembled in mating shells with components assembled in and confined by attached shells that facilitate rapid and accurate fabrication.Type: GrantFiled: December 15, 2000Date of Patent: January 6, 2004Assignee: Origin MedsystemsInventors: Tenny Chang, Charles Gresl, John Lunsford, Jon A. Sherman, Theodore A. Richardson
