  • Implantable arrangement for the defibrillation or cardioversion of a heart
    Patent number: 5235978
    Abstract: An implantable arrangement for effecting in vivo defibrillation or cardioversion of a heart has a first electrode disposed in the inferior vena cava, a second electrode disposed in the right ventricle, and a planar electrode disposed outside of the heart. Pulse generating means are provided which simultaneously charge all three electrodes with pulses. An optimally low energy for successfully achieving defibrillation is thereby achieved.
    Type: Grant
    Filed: June 9, 1992
    Date of Patent: August 17, 1993

  • Electrode arrangement for an implantable defibrillator/cardioverter
    Patent number: 5235977
    Abstract: An electrode arrangement for an implantable defibrillator/cardioverter has two intravascular electrodes, one of which is disposed in the inferior vena cava. The arrangement has a third, planar electrode, which is disposed outside of the heart. Placement of one of the intravascular electrodes in the inferior vena cava, instead of in the right ventricle as in known systems, achieves a high utilization of the defibrillation energy without the presence of an endocardial electrode.
