Abstract

A cardiac stimulation device having a reduced volumetric configuration contains a pair of high-voltage cylindrical discharge capacitors positioned at rounded edges within a device container. The capacitors have electrical contact tabs at one end which are inserted directly through apertures formed within an associated electronic module. The capacitor tabs are connected directly to the electronic module eliminating the need for secondary connectors or point to point wiring, thus reducing the number of connections. Direct connection of the capacitors to the electronic module allows for optimal positioning of the module within the container. Specifically, the generally planar module is oriented perpendicular to planar cover surfaces of the container. Irregularly shaped components attached to the surface of the module advantageously extend away from the surface into remaining voids within the container. Adhesive compressible foam is placed around and between the internal components of the stimulation device to stabilize the device against shock and vibration.
