Patent ID: 8543201

Claim:
An implantable medical device comprising: one or more leads for sensing electrical signals of a patient or for applying electrical energy to the patient; a monitoring circuit for monitoring heart activity of the patient through one or more of the leads; and a therapy circuit for delivering electrical energy through one or more of the leads to a heart of the patient, wherein the therapy circuit includes a capacitor, the capacitor comprising: a plurality of anodes, each anode comprising an anode foil having a formation voltage of approximately 441 volts or greater and having a porous structure; a plurality of cathodes; a plurality of electrolyte impregnated separators, wherein the capacitor is formed in a stack having alternating anodes and cathodes and at least one of the plurality of electrolyte impregnated separators located between each anode and each cathode; wherein each of the plurality of anodes includes a separate connection member attached to the anode, the connection member having a first section extending over and confronting a front edge face of the anode, wherein the connection member comprises a main member having a generally L-shaped cross-section; and and wherein adjacent anodes are stacked so that their respective connection members are positioned in a stacked relationship adjacent to each other such that the outer faces of the adjacent connection members are substantially planar relative to each other.
