A battery having flat, stacked, anode and cathode layers. The battery can be adapted to fit within an implantable medical device.

Batteries including a flat plate design

One aspect provides a capacitor feedthrough assembly having an electrically conductive member dimensioned to extend at least partially through a feedthrough hole of a case of the capacitor, the conductive member having a passage therethrough.

Flat capacitor for an implantable medical device

A flat capacitor includes a case having a feedthrough hole, a capacitor stack located within the case, a coupling member having a base surface directly attached to the capacitor stack and having a portion extending through the feedthrough hole, the coupling member having a mounting hole, a feedthrough conductor having a portion mounted within the mounting hole, and a sealing member adjacent the feedthrough hole and the feedthrough conductor for sealing the feedthrough hole. Other aspects of the invention include various implantable medical devices, such as pacemakers, defibrillators, and cardioverters, incorporating one or more features of the exemplary feedthrough assembly.

Capacitor having a feedthrough assembly with a coupling member

One aspect provides a capacitor having a first stack of capacitive elements a second stack of capacitive elements, wherein the first and second stacks are enclosed in separate compartments of a capacitor case that electrically isolate the electrolytes of each stack from one another.

In one aspect, a method of manufacturing a capacitor includes disposing one or more conductive layers of a first electrode stack in a recess of an alignment mechanism, where the recess is positioned relative to two or more alignment elements. The method further includes placing a separator over the one or more conductive layers where an outer edge of the separator contacts the two or more alignment elements. In one embodiment, a capacitor includes anode and cathode foils having offsetting edge portions. In one embodiment, a multiple tab cathode for a flat capacitor. A plurality of cathode tabs are portioned into a plurality of cathode tab groups positioned in different locations along the edge of the capacitor stack to reduce the amount of space required for connecting and routing the cathode tabs.

Method of constructing a capacitor stack for a flat capacitor

One embodiment includes a capacitor having a first anode stack having a first number of anode foils, a second anode stack having a second number of anode foils, where the first number of anode foils is different than the second number of anode foils. Another aspect provides a capacitor having a case having a curved interior surface, and first, second, and third capacitor modules that confront the curved interior surface of the case. One aspect provides a capacitor having one or more anodes and a cathode structure comprising a plurality of integrally connected cathode plates, the cathode structure having a serpentine shape, interweaving under and over each of the one or more anodes. One aspect provides a feedthrough assembly having an electrically conductive member dimensioned to extend at least partially through a feedthrough hole of a case of the capacitor, the conductive member having a passage therethrough. One aspect provides a capacitor having a first stack of capacitive elements a second stack of capacitive elements, wherein the first and second stacks are enclosed in separate compartments of a capacitor case that electrically isolate the electrolytes of each stack from one another. One aspect provides a capacitor case including a portion having opposing interior and exterior surfaces, with the portion having a hole; and a semi-permeable membrane adjacent the hole to regulate passage of fluids through the hole.
