Abstract: A capacitor for powering an implantable medical device is described. The capacitor includes a casing having contoured surfaces to more closely conform to body contours. This means that the anode housed in the casing must also have a contoured shape substantially matching that of the casing. Accordingly, the anode is comprised of a pressed pellet having a surrounding peripheral edge extending to spaced-apart first and second major face walls. An anode lead wire comprises an embedded portion extending into the anode pellet. First and second channel-shaped recesses aligned with each other extend into the anode pellet from the first and second major face walls to intersect with the embedded lead wire portion. The first and second channel-shaped recesses also extend to opposed locations at the surrounding peripheral edge of the anode pellet. The anode pellet is bent at the aligned first and second channel-shaped recesses to provide a right anode pellet portion electrically connected to a left anode pellet portion by the embedded lead wire portion. The thusly contoured anode pellet has an anatomical shape that matches that of the contoured casing to provide an implantable capacitor that is volumetrically efficient.

Abstract: A nickel termination-pad that has been clad-bonded to a titanium base layer electrically contacted to a casing to thereby serve as a surface for a device manufacturer to connect electronic circuit to the capacitor is described. The clad connection of the nickel termination-pad to the titanium base layer is both robust and provides good electrical conductivity between the dissimilar metals.

Abstract: A wet tantalum capacitor of either a single anode design or of multiple anode configurations having cathode active material supported on the casing and sealed in its own separator material is described. The separator “covers’ the cathode active material and is adhered directly to the casing. For a multiple anode design, an inner cathode foil positioned between opposed anode pellets is sealed in its own separator bag. Preferably, a polymeric restraining device prevents the anode from contacting the casing. The completed anode/cathode electrode assembly is sealed in the casing, which is filled with electrolyte thru a port. The fill port is hermetically sealed to complete the capacitor.
