    摘要： An implantable medical device such as a defibrillator is described. The device includes an hermetically sealed housing containing a flat electrolytic capacitor and an energy source such as a battery. The battery is connected to the capacitor and provides charge thereto. The capacitor stores the charge at a relatively high voltage. The charge stored in the capacitor is discharged through a defibrillation lead to a site on or in the heart when fibrillation of the heart is detected by the implantable medical device. Methods of making and using the implantable medical device, the capacitor, and their various components are disclosed.

    摘要： Flat electrolytic capacitors particularly for use in implantable medical devices having stacked cathode and anode layers particular electrical connections of the capacitor anode and cathode layers with a capacitor connector assembly. Anode terminal means extend through the capacitor case side wall for electrically connecting a plurality of the anode tabs to one another and providing an anode connection terminal at the exterior of the case that is electrically insulated from the case. A cathode terminal extends through or to an encapsulation area of the capacitor case side wall via a cathode terminal passageway for electrically connecting a plurality of the cathode tabs to one another and providing a cathode connection terminal at the exterior of the case. The connector assembly is electrically attached to the anode connection terminal for making electrical connection with the anode tabs and to the cathode connection terminal for making electrical connection with the cathode tabs. The cathode terminal passageway comprises a cathode opening extending through the case wall, and the cathode terminal comprises a cathode wire or feedthrough pin extending from the gathered cathode tabs into or through the cathode opening providing the cathode connection terminal electrically connected with the case. Alternatively, the terminal passageway comprises a portion of an interior ledge of the side wall upper opening edge having a width and depth depressed below the upper opening edge and a cover edge portion overlying the ledge to trap the cathode terminal when the cover is welded to the crimped upper edge. The cathode terminal comprises a cathode tab extension foil attached to the gathered cathode tabs or an extension of one, a plurality or all of the cathode tabs.
