  • Defibrillation shock output circuit
    Patent number: 8489187
    Abstract: This document discusses, among other things, techniques for generating and delivering a high voltage defibrillation shock using an implantable cardiac rhythm management device. An output energy delivery bridge can be programmed to provide desired shock vectors or polarities. A bootstrapped fully solid-state switch control voltage generation circuit is described. Automatic polarity or vector reconfiguration embodiments are described, such as in response to an unsuccessful attempt to convert the heart to a normal rhythm.
    Type: Grant
    Filed: February 8, 2012
    Date of Patent: July 16, 2013
    Assignee: Cardiac Pacemakers, Inc.
    Inventors: William J. Linder, Hari Sree
