View page
US Patent:
6928322, Aug 9, 2005
Filed:
Jan 30, 2003
Appl. No.:
10/356087
Inventors:
Daniel Yerkovich - Seattle WA, US
Gregory T. Kavounas - Kirkland WA, US
Assignee:
Medtronic Physio-Control Manufacturing Corporation - Redmond WA
International Classification:
A61N001/39
US Classification:
607 5
Abstract:
A system is provided for delivering a defibrillation pulse to a patient and a corresponding method of storing such a system is provided in accordance with the present invention. The system includes a defibrillator (e. g. , an AED) that is configured to deliver the defibrillation pulse to the patient and a cell that is configured to convert light into electrical power for the defibrillator. The method includes storing an defibrillator of the system for future use and arranging a light receiving system to receive light such that the light receiving system converts light into electrical power for the defibrillator.

US Patent:
7570994, Aug 4, 2009
Filed:
Apr 25, 2003
Appl. No.:
10/423805
Inventors:
Paul S. Tamura - Seattle WA, US
Daniel Yerkovich - Seattle WA, US
Patrick F. Kelly - Edmonds WA, US
Richard Nova - Kirkland WA, US
Joseph Bradley Williamson - Mercer Island WA, US
Stephen B. Johnson - Clinton WA, US
Gary DeBardi - Kirkland WA, US
Assignee:
Medtronic Physio-Control Corp. - Redmond WA
International Classification:
A61N 1/39
US Classification:
607 5, 607 33, 607 61, 320111, 600300
Abstract:
Defibrillator assemblies and methods to wirelessly transfer energy from an external source to a battery or other rechargeable power source within the defibrillator assembly. The transfer of energy may be through a non-contact interface on a defibrillator cradle or a docking station that mounts the defibrillator. The rate of energy transfer may be equal to the energy drain caused by self-discharge and automated self-testing. Accordingly, since the rate of energy transfer is lower than that required to run the defibrillator system continuously, several wireless methods of energy transfer may be used. In addition, the defibrillator assembly may communicate diagnostic and non-diagnostic data to the external source.

US Patent:
7917209, Mar 29, 2011
Filed:
Jun 27, 2005
Appl. No.:
11/167247
Inventors:
Tae H. Joo - Redmond WA, US
Ronald E. Stickney - Edmonds WA, US
Cynthia P. Jayne - Redmond WA, US
Paula Lank - Renton WA, US
Patricia O'Hearn - Mercer Island WA, US
David R. Hampton - Woodinville WA, US
James W. Taylor - Sammamish WA, US

Daniel Yerkovich - Seattle WA, US
Assignee:
Physio-Control, Inc. - Redmond WA
International Classification:
A61N 1/39
US Classification:
607 6
Abstract:
The presence of a cardiac pulse in a patient is determined by evaluating physiological signals in the patient. In one embodiment, a medical device evaluates two or more different physiological signals, such as phonocardiogram (PCG) signals, electrocardiogram (ECG) signals, patient impedance signals, piezoelectric signals, and accelerometer signals for features indicative of the presence of a cardiac pulse. Using these features, the medical device determines whether a cardiac pulse is present in the patient. The medical device may also be configured to report whether the patient is in a VF, VT, asystole, or PEA condition, in addition to being in a pulseless condition, and prompt different therapies, such as chest compressions, rescue breathing, defibrillation, and PEA-specific electrotherapy, depending on the analysis of the physiological signals. Auto-capture of a cardiac pulse using pacing stimuli is further provided.

US Patent:
20040267322, Dec 30, 2004
Filed:
Jun 27, 2003
Appl. No.:
10/608239
Inventors:
Gregory Kavounas - Kirkland WA, US
Richard Nova - Kirkland WA, US
Joseph Williamson - Mercer Island WA, US
Stephen Johnson - Clinton WA, US
Daniel Yerkovich - Seattle WA, US
Patrick Kelly - Edmonds WA, US
Paul Tamura - Seattle WA, US
Assignee:
Medtronic Physio-Control Corp. - Redmond WA
International Classification:
A61N001/39
US Classification:
607/005000
Abstract:
The present invention provides a portable defibrillator having a capacitor adapted to receive an electrical charge to deliver a defibrillation charge. Power terminals are provided to receive line power. A charging circuit is provided to charge the capacitor from line power after the power terminals receive line power. Therefore, the defibrillator is capable of receiving line power, such as standard 120 VAC, to charge the defibrillator's capacitor. By charging the capacitor directly through line power, the capacitor is charged in much less time than searching for and replacing a defibrillator battery.
