Embodiment Construction

[0043] For a general understanding of the present invention, reference is made to the drawings. In the drawings, like reference numerals have been used throughout to designate identical elements.

[0044] The present invention is directed to methods and apparatus for making a hermetic device containing a detectable gas. A device fabricated according to the methods and apparatus of the present invention may subsequently be placed in a testing device which is capable of detecting the detectable gas, and thus confirming that the device is hermetic, or is not hermetic, and therefore is defective.

[0045] Referring now to the drawings, FIG. 1 shows a perspective view and FIG. 2 shows a cross-sectional view of an exemplary electrochemical cell 10 as a hermetic device provided with hermetic sealing means, for example, spherical shaped sealing member 12. While cell 10 is shown having a half-rounded shape, it will be readily apparent to those skilled in the art that in their broadest form such ...

Abstract

An apparatus for making a hermetic device containing a detectable gas and comprising a surface having a fill port comprising a vacuum pump in communication with the hermetic device through a vacuum conduit; a liquid reservoir for containing liquid to be delivered to the hermetic-device; a gas reservoir for containing a detectable gas to be delivered to the hermetic device; a transfer vessel for transferring a selected quantity of liquid and gas to the hermetic device; and a block for passing the selected quantity of liquid and gas through a fill port of the hermetic device, and disposing a seal into the fill port. A method for making a hermetic device containing a detectable gas, and an exemplary hermetic device comprising an electrochemical cell or a capacitor are also disclosed.

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS [0001] This application claims priority from U.S. Provisional Application Ser. No. 60 / 673,514, filed Apr. 22, 2005, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention generally related to quality control of hermetic devices and, more particularly, to leak detection of sealed enclosures to ensure their hermeticity after completion of manufacturing. Leak detection is enabled by providing a detectable gas within the container during the hermetic device manufacturing process. Confirming hermeticity is critical for any sealed enclosure, especially one housing an electrical power source for an implantable medical device. The power source can be either an electrochemical cell or a capacitor. [0004] In either case, the power source includes a negative electrode and a positive electrode physically segregated from each other by a separator and provi...
