  • Publication number: 20150030913
    Abstract: A battery having an electrode assembly located in a housing that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery housing provides a cover and a shallow case a preferably planar, major bottom portion, an open top to receive the cover opposing the bottom portion, and a plurality of sides being radiused at intersections with each other and with the bottom to allow for the close abutting of other components located within the implantable device while also providing for efficient location of the battery within an arcuate edge of the device. The cover and the shallow case being substantially hermetically sealed by a laser weld technique and an insulator member disposed within the case to provide a barrier to incident laser radiation so that during welding radiation does not impinge upon radiation sensitive component(s) disposed within the case.

  • Publication number: 20100304213
    Abstract: A method of manufacturing an energy storage device for a medical device includes enclosing a cell assembly in a case. The case includes a filling aperture. The filling aperture includes an inner surface that is integral to the case so as to be monolithic. The case is free of a separate fill port tube. Moreover, the method includes introducing an electrolyte into the case through the filling aperture and hermetically sealing the filling aperture to form a first seal of the filling aperture that is free of a filler material. The method additionally includes hermetically sealing the sealing member to the case to form a second seal of the filling aperture.

  • Patent number: 6132896
    Abstract: An electrochemical cell has a silver vanadium oxide cathode material formed into a pellet shape which expands as the cell is discharged. A cathode current collector circumferentially surrounds the cathode pellet and is in contact with the peripheral edge of the cathode pellet to prevent peripheral cathode expansion. The peripheral cathode current collector maintains a stable cell impedance during cell discharge. The cell has a D-shaped housing in which the cathode is disposed adjacent to a first interior surface, and a lithium anode is disposed adjacent to a second interior surface.
