Patent number: 8388612Abstract: An electrosurgical return electrode includes a conductive pad including a patient-contacting surface configured to conduct electrosurgical energy, and a temperature sensing circuit coupled to the conductive pad. The temperature sensing circuit includes a plurality of switching elements connected in series, wherein each of the plurality of switching elements is configured to vary in impedance in response to temperature changes, such that an interrogation signal transmitted therethrough is indicative of the temperature change.Type: GrantFiled: May 11, 2007Date of Patent: March 5, 2013Assignee: Covidien LPInventors: James E. Dunning, Peter Gadsby, David Gresback

Publication number: 20120283721Abstract: An electrosurgical return electrode is disclosed. The return electrode includes a first and second flexible conductive material layers and a material layer disposed between the first and second conductive material layers. The material layer is transitionable between a solid state and a non-solid state, the material layer is also configured to melt upon an increase in temperature beyond a predetermined threshold, thereby increasing conductivity between the first and second conductive material layer.Type: ApplicationFiled: July 17, 2012Publication date: November 8, 2012Applicant: TYCO HEALTHCARE GROUP LPInventors: James E. Dunning, Peter Gadsby, David Gresback

Patent number: 7742828Abstract: A medical electrode, and a method of making a medical electrode. The electrode comprises an electrode member having a top face and a bottom face; disconnected regions of electrically conductive material in electrical contact with the top face of the electrode member, patient contacting layer and an electrical connector in electrical contact with the disconnected regions. The disconnected regions reduce patient skin irritation and burning while optimizing electrical impedance of the electrode.Type: GrantFiled: September 29, 2006Date of Patent: June 22, 2010Assignee: Tyco Healthcare Group LPInventors: Peter Gadsby, Peter F. Meyer, Scott Coggins
