ABSTRACT:
Implantable defibrillators are implanted into the chests of patients prone to suffering ventricular fibrillation, a potentially fatal heart condition. Critical components in these devices are aluminum electrolytic capacitors, which store and deliver one or more life-saving bursts of electric charge to a fibrillating heart. These capacitors make up about one third the total size of the defibrillators. Unfortunately, manufacturers of these capacitors have paid little or no attention to reducing the size of these capacitors through improved capacitor packaging. Accordingly, the inventors devised a unique capacitor lid, or header, assembly that allows size reduction. Specifically, one embodiment of the header assembly includes two recesses, each with a depth that allows the head of a rivet (or other fastener) to be substantially flush, or coplanar, with the underside of the header. Another embodiment includes a single recess to receive two rivet heads. The recesses reduce the vertical space necessary to ensure separation of the rivets from internal components of the capacitor and thus allow reduction in the overall height of the capacitor and size of devices, such as implantable defibrillators, that use them.
