Patent number: 7251527Abstract: A system is described. The system includes a lithium battery, a charge storage capacitor electrically connected to the lithium battery, a first device, and at least one second device. The first device is electrically connected to the lithium battery and is powered by the lithium battery. The at least one second device is attached to the charge storage capacitor and adapted to read a rate of charge storage in the charge storage capacitor or to calculate the rate of charge storage by measuring both a time of charging and a charge stored or added to the charge storage capacitor during the time of charging.Type: GrantFiled: July 31, 2003Date of Patent: July 31, 2007Assignee: Cardiac Pacemakers, Inc.Inventor: Michael J.

Patent number: 7060030Abstract: This document discusses a system that includes an intermediary telemetry interface device for communicating between a cardiac rhythm management system or other implantable medical device and a programmer or other remote device. One example provides an inductive near-field communication link between the telemetry interface and the implantable medical device, and a radio-frequency (RF) far-field communication link between the telemetry interface device and the remote device. The telemetry interface device provides data buffering. In another example, the telemetry interface device includes a data processing module for compressing and/or decompressing data, or for extracting information from data. Such information extraction may include obtaining heart rate, interval, and/or depolarization morphology information from an electrogram signal received from the implantable medical device.Type: GrantFiled: January 8, 2002Date of Patent: June 13, 2006Assignee: Cardiac Pacemakers, Inc.Inventors: Jeffrey A. Von Arx, Michael J. Lyden, William J. Linder, Scott T. Mazar, Allan T. Koshiol, Mark Gryzwa, Dorothy Nauman, Scott Hostine

Patent number: 6892096Abstract: It is important in cardiac pacing devices and systems to achieve efficient power utilization and conservation to extend the life of the battery cells, thereby extending the intervals between invasive medical procedures to replace components in the cardiac pacing system. A device and method are provided. The cardiac pacing device comprises a battery, a discrete time switched capacitor pacing power supply comprising a charge transfer capacitor bank comprising at least two capacitors, and a pace output supply capacitor which can discharge current to the tissue of a patient. A pacing supply design has a multiplicity of battery voltage multiplication factors and operating frequency settings. The pacing supply, voltage multiplier settings and operating frequency are automatically adjusted to compensate for changing pace output settings, load, cardiac cycle rate, and/or battery condition.Type: GrantFiled: January 28, 2002Date of Patent: May 10, 2005Assignee: Cardiac Pacemakers, Inc.Inventor: Michael J. Lyden

Publication number: 20040073264Abstract: A system is described which has a battery, a device which is powered by the battery in an episodic manner, and a charge storage capacitor. The system has attached to the charge storage capacitor a device or devices capable of: reading the rate of charge storage; or measuring both time and charge stored or added to the charge storage capacitor so that a rate of charge storage may be calculated. The estimated replacement time for the battery, particularly for a lithium battery in a pacing device, is easily estimated. Also described herein is a process for estimating a level of energy depletion in the system.Type: ApplicationFiled: October 7, 2003Publication date: April 15, 2004Applicant: Cardiac Pacemakers, Inc.Inventor: Michael J.
