Patent ID: 7656646

Claim:
A method of producing an apparatus for use in a patient, comprising: etching an anode foil; anodizing the anode foil; assembling the anode foil, at least one cathode foil and one or more separators into first and second capacitor stacks, each adapted to deliver from about 5.3 joules per cubic centimeter of capacitor stack volume to about 6.3 joules per cubic centimeter of capacitor stack volume at a voltage of between about 465 volts to about 620 volts; connecting the first and second capacitor stacks in parallel using a flexible interconnect; inserting the first and second capacitor stacks into a capacitor case; inserting the capacitor case into a device housing adapted for implant in a patient; coupling the first and second capacitor stacks to a component so that the first and second capacitor stacks are in electrical communication with the component; and sealing the device housing.
