    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: A sealed electrode enclosed in separator material is provided for use in a capacitor cell. The separator may either be adhered to the electrode in sheets, or may be formed into a pouch, which is used to enclose the electrode. A method of preparing the electrode sealed with separator is described in which an adhesive is used to secure the pouch to the electrode before sealing it. The prefabricated electrode and separator combination may be used in both coiled capacitor cells and flat capacitor cells that are often used in implantable medical devices. Electrodes prepared in this fashion can be efficiently and reliably aligned within the case of a capacitor cell, and have no exposed electrode surfaces that could lead to short-circuiting within the cell.
