Description

ABSTRACT:
An implantable defibrillator arrangement has a housing adapted for in vivo implantation in a patient, the housing containing a capacitor connectable through a controllable switch arrangement to a voltage source for charging, and two electrodes attached in vivo to the heart. An inductance is also provided for assisting in the generation of an electrical defibrillation pulse, the inductance being contained in a second, separate housing provided with terminals for electrically connecting the inductance via leads to the other housing and to one of the electrodes. The inductance can thereby be easily changed, by connecting an inductance in a second housing having an appropriate value, so as to match the defibrillation pulse to different electrode configuration. It is also possible to provide further passive components in the second, separate housing.
