  • Current waveforms for anti-bradycardia pacing for a subcutaneous implantable cardioverter-defibrillator
    Patent number: 7502645
    Abstract: A power supply for an implantable cardioverter-defibrillator for subcutaneous positioning between the third rib and the twelfth rib and using a lead system that does not directly contact a patient's heart or reside in the intrathoracic blood vessels and for providing anti-bradycardia pacing energy to the heart, comprising a capacitor subsystem for storing the anti-bradycardia pacing energy for delivery to the patient's heart; and a battery subsystem electrically coupled to the capacitor subsystem for providing the anti-bradycardia pacing energy to the capacitor subsystem.
    Type: Grant
    Filed: February 18, 2005
    Date of Patent: March 10, 2009
    Assignee: Cameron Health, Inc.
    Inventors: Alan H. Ostroff, William J. Rissmann, Gary R. Mezack, Gust H. Bardy
  • Switched capacitor defibrillation circuit
    Patent number: 6778860
    Abstract: A defibrillator circuit for generating a rectangular waveform across a patient from capacitively stored energy and employing a plurality of capacitors initially chargeable to a common voltage and thereafter sequentially switchable into parallel relation with one another so as to raise the voltage supplied to an H-bridge circuit from a point of decay back to said common voltage.
