The present invention is directed to any electrochemical cell casing design having an electrolyte fill aperture. The electrolyte fill aperture receives and directs the electrolyte into the casing. A fill plug has at least two components&#x2014;an insert section detachably connected to a placement unit. The placement unit allows a user to properly position the insert section into the electrolyte fill aperture. Once this is done, the placement unit is detached from the insert section. The insert section in then hermetically sealed to the casing. If desired, the fill plug can be used for filling the electrolyte in the casing.

A header assembly mounted to a medical device for connecting to at least one conductor lead terminating at a target organ or portion of the body intending to be assisted is described. The header assembly comprises a body of polymeric material supporting at least one unitary conductor wire. The conductor wire connects between a feedthrough wire exiting the medical device and a terminal block into which the conductor lead plugs. Various structures are described for connecting the conductor wire to the feedthrough wire.

A unitary lid for the casing of an electrochemical energy storage device is described. The lid has a terminal lead ferrule and a fillport formed from a single blank in a machining process. The lid does not require any welding except for securing it to the open end of a casing container. This helps the lid contribute to the cell's volumetric efficiency, which is especially important for cells powering implantable medical device.

A resistance welding electrode that is particularly suited for resistance spot welding a workpiece to a substrate without cross-contaminating specific portions of the workpiece is described. This is done by sheathing an internal surface of the welding electrode with a thermoplastic polymeric material. Then, there is only contact between the welding electrode and the workpiece at the very distal end of the electrode adjacent to where the workpiece is to be connected to the substrate. Contamination in this area is not detrimental because subsequent workpiece plating does not take place there.
