Patent number: 11759623Abstract: Techniques for calibrating a low frequency (LF) clock of an IMD are disclosed, wherein the IMD also includes a high frequency (HF) clock. This includes determining an average, or a surrogate thereof, of how many HF clock cycles of a HF clock signal (produced by the HF clock) occur per LF clock cycle of a predetermined number N of LF clock cycles of the LF clock signal (produced by the LF clock), wherein N is an integer that is at least 2. This also includes comparing the average or a surrogate thereof to a corresponding target value that the average or the surrogate thereof would be equal to if the frequency of the LF clock signal equaled a target frequency for the LF clock, wherein the corresponding target value need not be an integer. The LF clock is calibrated by adjusting the frequency thereof based on results of the comparing.Type: GrantFiled: October 27, 2020Date of Patent: September 19, 2023Assignee: Pacesetter, Inc.Inventors: Dean Andersen, Eiji Shirai

Patent number: 11331507Abstract: Implantable cardioverter device (ICD) systems capable of delivering a multi-vector defibrillation shock, and methods for use therewith, are described herein. Such an ICD system can include a defibrillation charge capacitor, a charge circuit, first, second, and third electrodes, switches, a controller, and first, second and third filters. The defibrillation charge capacitor is coupled between a first voltage rail and a second voltage rail. The first filter is coupled between the first and second electrodes, and the second filter is coupled between the second and third electrodes, so that the first and second filters can shunt EMI signals. The third filter is coupled between the first and third electrodes and configured to provide for electrical symmetry when the first, second, and third electrodes are used to deliver a multi-vector defibrillation shock. Such filters, which can be implemented using capacitors, can be used to make the ICD system MRI compatible.Type: GrantFiled: October 25, 2019Date of Patent: May 17, 2022Assignee: Pacesetter, Inc.Inventors: Jeffery Crook, Eiji Shirai, Arpitha Ravishankar
