Patent number: 9561106Abstract: A chamber or vasculature of a heart may be accessed via the pericardial space of the heart. Initially, the pericardial space may be accessed via a transmyocardial approach or a subxiphoid approach. A lead or other implantable apparatus may thus be routed into the pericardial space, through myocardial tissue and into the chamber or vasculature. The lead or other apparatus may be used to sense activity in or provide therapy to the heart.Type: GrantFiled: August 20, 2013Date of Patent: February 7, 2017Assignee: PACESETTER, INC.Inventors: Yougandh Chitre, Gene A. Bornzin, John R. Helland, Eric Falkenberg, Kevin L. Morgan, Sheldon Williams, Michael Yang, Andrew W. McGarvey

Patent number: 9282895Abstract: In an implantable medical device for monitoring glucose concentration in the blood, a blood-glucose concentration analysis is performed using correlations of blood-glucose concentration with measures of metabolic oxygen consumption including oxymetric, and/or temperature. Analysis of electrocardiographic data is used in a parallel method to detect and/or confirm the onset and/or existence and/or extent of hypoglycemia and/or hyperglycemia. Blood-glucose concentration calculation is enhanced by using the combination of the oxygen metabolism analysis and electrocardiographic analysis.Type: GrantFiled: December 10, 2013Date of Patent: March 15, 2016Assignee: Pacesetter, Inc.Inventors: Brian Jeffrey Wenzel, Taraneh Ghaffari Farazi, Euljoon Park, Eric Falkenberg, Michael E.

Patent number: 9162067Abstract: Embodiments of the present invention relate to implantable systems, and methods for use therewith, for monitoring myocardial electro-mechanical stability, and responding to the same. One or more signal indicative of electrical functioning of a patient's heart is obtained, as is one or more signal indicative of mechanical functioning of the patient's heart. The patient's myocardial electrical stability is monitored based on the one or more signal indicative of electrical functioning of the patient's heart, and the patient's myocardial mechanical stability is monitored based on the one or more signal indicative of mechanical functioning of the patient's heart. Based on both the myocardial electrical stability and myocardial mechanical stability, the patient's risk of an adverse cardiac event is monitored. Further, when the patient is at risk of an adverse cardiac event, a response is triggered that is specific to both the myocardial electrical stability and the myocardial mechanical stability.Type: GrantFiled: October 26, 2007Date of Patent: October 20, 2015Assignee: Pacesetter, Inc.Inventors: Taraneh Ghaffari Farazi, Eric Falkenberg, Euljoon Park

Patent number: 8548589Abstract: Implantable systems, and methods for use therein, perform at least one of a cardiac assessment and an autonomic assessment. Premature atrial contractions (PACs) are induced to thereby cause corresponding premature contractions in the ventricles. Short-term fluctuations in cardiac intervals, that follow the premature contractions in the ventricles caused by the induced PACs, are monitored. At least one of a cardiac assessment and an autonomic assessment is performed based on the monitored fluctuations in cardiac intervals that follow the premature contractions in the ventricles caused by the induced PACs. This can include assessing a patient's risk of sudden cardiac death (SCD), assessing a patient's autonomic tone and/or detecting myocardial ischemic events based on the monitored fluctuations in cardiac intervals that follow the premature contractions in the ventricles caused by the induced PACs.Type: GrantFiled: July 16, 2009Date of Patent: October 1, 2013Assignee: Pacesetter, Inc.Inventors: Taraneh Ghaffari Farazi, Eric Falkenberg

Patent number: 7925343Abstract: A subcutaneous implantable cardiac device system applies defibrillation currents in pathways aligned with the heart's own electrical system to decrease defibrillation thresholds. In one implementation, one or more subcutaneous sensors detect ventricular fibrillation. Positioning of subcutaneous sensors and filtering result in improved sensing with reduced noise. A subcutaneous patch component of the system that is in communication with a subcutaneous pacemaker or cardioverter-defibrillator may perform the sensing and apply the defibrillation. The subcutaneous patch may include one or more electrodes that perform both sensing and defibrillation. Variations of the subcutaneous patch may include battery and capacitor for generating onboard defibrillation current and may also include a microprocessor for advanced programmable operation.Type: GrantFiled: October 6, 2006Date of Patent: April 12, 2011Assignee: Pacesetter, Inc.Inventors: Xiaoyi Min, Scott Salys, Yougandh Chitre, Eric Falkenberg, Gene A.

Patent number: 7634313Abstract: In one implementation, a failsafe method for implantable satellite pacemaker pacing is provided, which includes pacing with a satellite pacemaker and monitoring for a local pacing pulse with an other satellite pacemaker. This implementation further includes, pacing with a surrogate satellite pacemaker if the local pacing pulse is not detected by the other satellite pacemaker. Certain implementations may include transmitting a wireless signal from the other satellite pacemaker to a master pacemaker if the local pacing pulse is not detected by the other satellite pacemaker and using the master pacemaker to select the surrogate satellite pacemaker. Certain implementations may include monitoring for the local pacing pulse with a plurality of satellite and causing the plurality of satellite pacemakers to select the surrogate satellite pacemaker.Type: GrantFiled: April 11, 2005Date of Patent: December 15, 2009Assignee: Pacesetter, Inc.Inventors: Mark W.
