Abstract: Implantable medical devices (IMDs) and their various components, including flat electrolytic capacitors for same, and methods of making and using same and providing for outgassing of gases released during capacitor charge and discharge cycles are disclosed. A gas vent and liquid electrolyte barrier into the electrolyte fill tube lumen that is used to fill the interior case chamber with electrolyte and then needs to be closed to prevent leakage of electrolyte. The fill port is shaped to comprise a fill port tube having interior and exterior tube ends and a fill port ferrule intermediate the ends of the fill port tube and comprising a fill port ferrule flange extending transversely to and away from the fill port tube. The fill port ferrule is mounted in an opening disposed in one of the case wall and the cover wall with the ferrule flange in sealing engagement therewith to locate the exterior tube end extending outwardly away from the fill port ferrule flange and the interior tube end within the interior case chamber. A microporous plug is injected into and fills the fill port lumen, the plug formed of a microporous material allowing the escape of gas released from the liquid electrolyte during capacitor charging while preventing escape of liquid or vaporized electrolyte.

Abstract: 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.

Abstract: A body implanted device including a container having an opening through which extends an electrical feedthrough. The feedthrough includes a terminal of bio-stable material. A glass insulator is positioned around the terminal. The glass insulator is chosen from a CABAL-12 type composition or variation thereof. The terminal is comprised of a material which has thermal expansion characteristics compatible with the glass seal. For glass seals having a thermal expansion in the range of 6.8 to 8.0.times.10.sup.-6 in/in/.degree.C. the terminal is comprised of a thin layer of titanium metallurgically clad over niobium or tantalum. For glass seals having a thermal expansion in the range of 8.0 to 9.0.times.10.sup.-6 in/in/.degree.C. the terminal is comprised of platinum, platinum-iridium or alloys of either, or of pure titanium.
