The electrically conductive layer forms an electrode portion of the electrode assembly and a first surface to be placed adjacent a person's skin. The first impedance reduction system is configured to dispense a first amount of an electrically conductive gel onto the first surface of the electrically conductive layer in response to a first activation signal. The second impedance reduction system is configured to dispense a second amount of the electrically conductive gel onto the first surface of the electrically to conductive layer in response to a second activation signal.Type: ApplicationFiled: March 25, 2013Publication date: August 22, 2013Applicant: ZOLL MEDICAL CORPORATIONInventor: Zoll Medical Corporation

Patent number: 8498713Abstract: The present invention is a visor for retinal stimulation of visually impaired subjects. The visor comprises a frame, an external coil, a camera and a mounting system. A connector allows the external coil to be positioned along a first direction. A sliding device allows the external coil to be positioned along a second direction. Positioning of the visor on a subject's nose allows the external coil to be positioned along a third direction. Positioning of the external coil along the first, second or third direction is useful to maximize coupling RF coupling between the external coil and an internal coil implanted on a subject wearing the visor.Type: GrantFiled: October 28, 2007Date of Patent: July 30, 2013Assignee: Second Sight Medical Products, Inc.Inventors: Kelly H. McClure, Richard Agustin Castro, Sanjay Gaikwad, Da-Yu Chang, Scott M. Loftin, Rongqing Dai, Robert J. Greenberg

Patent number: 8489207Abstract: A medical device having a unit in communication with ancillary components wherein the unit and the ancillary components each have a sensory output through which communication with a user of the medical device may be accomplished and to which the user's attention directed. In one aspect, the medical device is an AED unit with associated pads, which are an ancillary component electrically connected to the AED unit. In this illustrative example, the unit has a unit sensory output (e.g., a speaker or a display), and the pads, and/or their associated packaging, have an ancillary sensory output (e.g. a speaker or display). Programming in the AED unit controls output to the sensory outputs such that the user's attention is directed between the unit and the ancillary components.Type: GrantFiled: January 5, 2010Date of Patent: July 16, 2013Inventors: Gintaras A Vaisnys, Glenn W. Laub, Giovanni C Meier

Patent number: 8463405Abstract: Handling or removal of a pair of defibrillator electrode pads from their package is detected in order to effectively time the issuance of prompts to guide the user. One plate of a capacitor is embedded in the package, the electrode pads and lead wires serving as the other plate. Impedance across the capacitor in an alternating current circuit is monitored to detect an increase in the distance between the pads and the package. The impedance level is determined, in a low-cost hardware solution, by rectifying and then integrating an output voltage of the capacitor to produce a voltage signal whose magnitude attenuates as the pads are handled or removed. In one embodiment, the above methodology is time-division multiplexed with an alternative process that identifies handling or removal based on pad-to-pad impedance. In a further embodiment, the capacitive configuration is replaced with an inductive one.Type: GrantFiled: June 1, 2004Date of Patent: June 11, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Douglas Roberts, Kim Hansen

Patent number: 8452393Abstract: A defibrillation system that utilizes a unique defibrillator paddle assembly. The defibrillator paddle assembly has a handle and a paddle head. The paddle head contains the conductive surface that is used to contact the muscle tissue of the heart during a defibrillation attempt. The paddle head is connected to the handle by a flexible connection. The flexible connection enables the relative orientation between the handle and the paddle head to be selectively adjusted. Accordingly, a physician can selectively change the orientation of the paddle head in relation to the handle in order to more effectively utilize the paddle assembly during a specific circumstance. The flexible connection between the handle and the paddle head can be adjusted either by manual bending or by utilizing adjustment controls that are present on the handle of the paddle assembly.Type: GrantFiled: November 7, 2005Date of Patent: May 28, 2013Inventors: Stephen T. Epstein, André Martens

Patent number: 8428751Abstract: According to an aspect of the present disclosure, an automatic external defibrillator configured to deliver electrical pulses and/or shocks to a heart of a patient during a cardiac emergency is provided and includes a housing supporting an electrical connector; a defibrillator electrode delivery system supported on the housing; and a pair of defibrillation electrode pads supported by the defibrillator electrode delivery system. Each of the pair of defibrillation electrode pads is pre-connected to the electrical connector of the housing. A hydrogel layer of each defibrillation electrode pad is retained by the defibrillator electrode delivery system in such a manner so as to reduce a moisture vapor transmission rate thereof.Type: GrantFiled: September 21, 2010Date of Patent: April 23, 2013Assignee: Covidien LPInventors: Warren Copp-Howland, Erick Garstka, David Selvitelli, Kathleen Tremblay, Caroline Gasiorski
