Patent number: 8235980Abstract: A return pad includes a backing, at least one return electrode, and at least one ring sensor. The backing has a top side, a bottom side, and a periphery. The return electrode is disposed on the bottom side of the backing layer and is adapted to connect to a current generator. The ring sensor(s) is disposed in substantial concentric registration with the periphery of the backing and is configured to connect to a measuring component. The measuring component is operable to approximate contact quality of the return electrode during electrosurgical application and is configured to communicate with the generator.Type: GrantFiled: December 14, 2011Date of Patent: August 7, 2012Assignee: TYCO Healthcare Group LPInventors: James E. Dunning, Jeffrey L. Eggleston, Kyle R. Rick

Patent number: 5720744Abstract: A control system and method for the operation of neurosurgical bipolar electrodes for application to the tissue and bodily fluids of a patient provides a source of high frequency energy connected to bipolar electrodes. Contacting surfaces are on the bipolar electrodes of highly electrically conductive material with resistance per unit area substantially less than the impedance of the tissue and bodily fluids. A current transducer attached to the source of high frequency energy responds to the RMS current applied through the tissue and bodily fluids between the contact surfaces as a measure relative to the instantaneous values of the RMS current. A current transducer attached to the source of high frequency energy responds to the RMS current through a capacitor applied across the contact surfaces to provide a signal correlated to the instantaneous values of the RMS voltage between the contacts and across the tissue and bodily fluids.Type: GrantFiled: June 6, 1995Date of Patent: February 24, 1998Assignee: Valleylab IncInventors: Jeffrey L.

Patent number: 5575789Abstract: A surgical safety apparatus for use in connection with an energizable surgical device prevents inadvertent activation of a surgical tool. The energizable surgical device may include an electrosurgical system, a laser scalpel, an ultrasonic aspirator, and combinations thereof. An activation circuit is in connection with the source of energy and in connection with the handpiece. The activation circuit has two states: the first state disconnects the source of energy from the handpiece, the second state connects the source of energy to the handpiece. A sensing element is connected to the activation circuit. The sensing element signals the activation circuit to convert the activation circuit from the first state to the second state. The activation circuit may remain in the second state for a preestablished period of time followed by a reversion to the first state. The activation circuit may include a relay which may be connected to operate accessories including smoke evacuators, lights, videos or irrigators.Type: GrantFiled: October 27, 1994Date of Patent: November 19, 1996Assignee: Valleylab Inc.Inventors: Gregory J.
