Patent number: 8442635Abstract: This document discusses, among other things, systems and methods for automatic electrode integrity management. Interelectrode impedance is measured for various electrode combinations of an implantable cardiac function management device. The impedance data is processed, such as at an external remote server, to determine whether an electrode is failing or has failed, to select an alternate electrode configuration, to alert a physician or patient, to predict a time-to-failure such as by using population data, or to reprogram electrode configuration or other device parameters of the implantable cardiac function management device.Type: GrantFiled: February 22, 2011Date of Patent: May 14, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Derek D.

Patent number: 8185202Abstract: Methods and devices for reducing phrenic nerve stimulation of cardiac pacing systems involve delivering a pacing pulse to a ventricle of a heart. A transthoracic impedance signal is sensed, and a deviation in the signal resulting from the pacing pulse may be used to determine phrenic nerve stimulation. Methods may further involve detecting the phrenic nerve stimulation from the pacing pulse by delivering two or more pacing pulse to the ventricle of the heart, and determining a temporal relationship. A pacing vector may be selected from the two or more vectors that effects cardiac capture and reduces the phrenic nerve stimulation. A pacing voltage and/or pulse width may be selected that provides cardiac capture and reduces the phrenic nerve stimulation. In other embodiments, a pacing pulse width and a pacing voltage may be selected from a patient's strength-duration curve that effects cardiac capture and reduces the phrenic nerve stimulation.Type: GrantFiled: May 22, 2008Date of Patent: May 22, 2012Assignee: Cardiac Pacemakers, Inc.Inventor: Alok S.

Publication number: 20110224751Abstract: A methods and devices for capture detection are based on sensing a propagated depolarization from a contralateral cardiac chamber. An intersite sensing interval is determined based on an intersite pacing delay and an intersite conduction delay associated with first and second pacing sites. Pacing pulses are delivered to the first pacing site and the second pacing site, the pacing pulses separated in time by the intersite pacing delay. An intersite sensing interval is timed. The process includes sensing, during the intersite sensing interval, at the first pacing site for a depolarization propagated to the first pacing site from the second pacing site. It a depolarization propagated from the second pacing site is not sensed, then capture of the first and second pacing sites is detected.Type: ApplicationFiled: May 10, 2011Publication date: September 15, 2011Inventors: Alok S.

Patent number: 7933651Abstract: Cardiac treatment methods and devices provide for templates representative of past tachyarrhythmia events, each template associated with a therapy. Methods involve providing a cardiac waveform representative of a patient's cardiac activity and identifying a portion that indicates an arrhythmic event. A cardiac template corresponding to the portion is generated, and a therapy is associated with the template useful for treating a subsequent arrhythmia. The waveform portion may be identified by a physician using a patient-external device to display the cardiac waveform. The template may be generated by a physician selecting the cardiac waveform, and determining if the therapy associated with the template was satisfactory and/or effective in treating the arrhythmia. Identification may involve matching the event to templates generated using cardiac waveforms other than the patient's cardiac waveforms.Type: GrantFiled: November 23, 2004Date of Patent: April 26, 2011Assignee: Cardiac Pacemakers, Inc.Inventors: Shelley Marie Cazares, Yayun Lin, Alok S.
