The method is further carried out by delivering RF power from the ablator module to the temperature simulator, and while delivering RF power, performing the steps of: communicating temperature signals from the temperature simulator to the ablator module, varying the communicated temperature signals, and verifying that a variation in the power output of the ablator module in response to varying the temperature signals conforms to the predefined manner.Type: GrantFiled: September 26, 2012Date of Patent: July 28, 2015Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Vadim Gliner, Assaf Govari

Publication number: 20150148858Abstract: An electrode assembly includes a first surface to be placed adjacent a person's skin and a second surface including a plurality of reservoirs of conductive gel. The plurality of reservoirs of conductive gel are disposed on sections of the electrode assembly that are at least partially physically separated and may move at least partially independently of one another to conform to contours of a body of a patient. The electrode assembly is configured to dispense an amount of the electrically conductive gel onto the first surface in response to an activation signal and to provide for a defibrillating shock to be applied to the patient through the amount of the electrically conductive gel.Type: ApplicationFiled: February 3, 2015Publication date: May 28, 2015Inventor: Thomas E.

Patent number: 9043001Abstract: Non-invasive electrical nerve stimulation devices and magnetic stimulation devices are disclosed, along with methods of treating medical disorders using energy that is delivered noninvasively by such devices. The disorders comprise migraine and other primary headaches such as cluster headaches, including sinus symptoms that resemble an immune-mediated response (“sinus” headaches), irrespective of whether those symptoms arise from an allergy that is co-morbid with the headache. The disclosed methods may also be used to treat other disorders that may be co-morbid with migraine headaches, such as anxiety disorders. In preferred embodiments of the disclosed methods, one or both of the patient's vagus nerves are stimulated non-invasively. In other embodiments, parts of the sympathetic nervous system and/or the adrenal glands are stimulated.Type: GrantFiled: September 16, 2013Date of Patent: May 26, 2015Assignee: Electrocore, LLCInventors: Bruce J. Simon, Joseph P. Errico, John T. Raffle

Patent number: 9037266Abstract: The present invention relates to a system and method for using the system. In particular, the present invention relates to an application, executable by a processing device to assess the organization of a non-nutritive suck (NNS) pattern of a patient and to entrain an organized NNS pattern in the patient. The software system receives data from an orofacial stimulation appliance to assess the patient's natural NNS pattern and generates a precise therapeutic pulse profile that is actuated as a tactile stimulus via the orofacial stimulation appliance to entrain an organized NNS pattern.Type: GrantFiled: April 26, 2012Date of Patent: May 19, 2015Assignee: Innara Health, Inc.Inventors: Steven M. Barlow, David L. Stalling, Kenneth Aron

Publication number: 20150112177Abstract: An electrode for use with an external defibrillator for a patient includes a first combination circuit including a circuit node electrically coupled to an adapter for coupling to the defibrillator. The circuit node is further coupled to a monitoring node defined by a monitoring segment of a first pad of the electrode and to a therapy node defined by a therapy segment of the first pad of the electrode. The therapy segment is electrically insulated from the monitoring segment. The first combination circuit further includes a capacitor coupled between the circuit node and the therapy node. The electrode of this disclosure hence provides additional solutions for reducing ECG artifact during the operation of the electrode.Type: ApplicationFiled: December 31, 2014Publication date: April 23, 2015Inventors: Ronald Eugene Stickney, Joseph L.
