Patent number: 8346357Abstract: Implementations of various technologies described herein are directed toward a sensing architecture for use in cardiac rhythm management devices. The sensing architecture may provide a method and means for certifying detected events by the cardiac rhythm management device. Moreover, by exploiting the enhanced capability to accurately identifying only those sensed events that are desirable, and preventing the use of events marked as suspect, the sensing architecture can better discriminate between rhythms appropriate for device therapy and those that are not.Type: GrantFiled: May 21, 2012Date of Patent: January 1, 2013Assignee: Cameron Health, Inc.Inventors: Surekha Palreddy, Jay A. Warren, James W. Phillips

Patent number: 8271208Abstract: A method for calibrating a flame ionization detector (FID). The method includes receiving a request to schedule a calibration. After scheduling the calibration, a flow request command is sent to a gas distribution system at a scheduled calibration. The flow request command instructs the gas distribution system to provide a gas at a gas concentration level to the FID. After the gas distribution system provides the gas at the gas concentration level to the FID, the method includes receiving a raw count from the FID and correlating the raw count with the gas and the gas concentration level provided to the FID. The method then stores the results of the correlation in a calibration log.Type: GrantFiled: May 29, 2009Date of Patent: September 18, 2012Assignee: LDARtools, Inc.Inventors: Jeremy Bolinger, Kevin Moses

Patent number: 8265749Abstract: Methods, systems, and devices for signal analysis in an implanted cardiac monitoring and treatment device such as an implantable cardioverter defibrillator. In illustrative examples, captured data including detected events is analyzed to identify likely overdetection of cardiac events. In some illustrative examples, when overdetection is identified, data may be modified to correct for overdetection, to reduce the impact of overdetection, or to ignore overdetected data. New methods for organizing the use of morphology and rate analysis in an overall architecture for rhythm classification and cardiac signal analysis are also discussed.Type: GrantFiled: December 14, 2009Date of Patent: September 11, 2012Assignee: Cameron Health, Inc.Inventors: Venugopal Allavatam, Surekha Palreddy, Rick Sanghera, Jay A.

Patent number: 8244349Abstract: Methods and devices that are configured to deliver cardiac stimuli in a particular fashion. In an illustrative embodiment, a method is used wherein a first stimulus is delivered using a first polarity, and, if the first stimulus fails to successfully convert an arrhythmia, a second stimulus having a second polarity that is different from or opposite of the first polarity is then delivered. Subsequent stimuli, if needed, are delivered in a continuing alternating-polarity manner. The first polarity may be determined by observing whether successfully-converting stimulus has been delivered previously and, if so, the polarity of the most recent stimulus that resulted in successful conversion is used as the first polarity. In additional embodiments, electrode configuration may be changed instead of or in addition to polarity, following unsuccessful stimulus delivery. Devices configured to perform such methods are included in additional illustrative embodiments.Type: GrantFiled: January 30, 2009Date of Patent: August 14, 2012Assignee: Cameron Health, Inc.Inventors: Rick Sanghera, Jay A. Warren

Patent number: 8135459Abstract: A unitary subcutaneous implantable cardioverter-defibrillator which has a long thin housing in the shape of a patient's rib. The housing contains a source of electrical energy, a capacitor, and operational circuitry that senses the presence of potentially fatal heart rhythms. Provided on the housing are cardioversion/defibrillation electrodes located to deliver electrical cardioversion-defibrillation energy when the operational circuitry senses a potentially fatal heart rhythm. The unitary subcutaneous implantable cardioverter-defibrillator does not have a transvenous, intracardiac, epicardial, or subcutaneous electrode.Type: GrantFiled: October 23, 2007Date of Patent: March 13, 2012Assignee: Cameron Health, Inc.Inventors: Gust H.

Patent number: 8116867Abstract: The present invention, in illustrative embodiments, includes methods and devices for analyzing cardiac signals in an implantable cardiac stimulus system. Within the analysis, a threshold may be defined related to a cardiac event rate. If the cardiac event rate does not exceed the threshold, filtering of captured cardiac signals occurs, including attenuating T-waves. If the cardiac event rate does exceed the threshold, circuitry for analog filtering or programming for digital filtering is bypassed to avoid attenuating low frequency components of the captured cardiac signals.Type: GrantFiled: August 4, 2005Date of Patent: February 14, 2012Assignee: Cameron Health, Inc.Inventor: Alan H. Ostroff
