Implantable medical device having flat electrolytic capacitor with cathode/case electrical connections

[Subject] The electrical connection of the layer of the negative pole of an electrolytic condenser and the anode which makes easy connection between an electrolytic condenser and the circuit of IMD, and the connector assembly of a capacitor is offered. [Solution means] An electrode stack assembly is equipped with two or more capacitor layers laminated, and each capacitor layer, It has an anode subassembly equipped with the cathode layer which has a negative pole tab, and the anode layer which has an anode tab, and a separator layer, and all the adjoining cathode layers and anode layers of a stack are insulated in a separator layer. An anode terminal means penetrates a capacitor case side wall, connects two or more anode tabs, and prepares the anode contact button insulated to the exterior of the case. A cathode terminal penetrates the 封止 domain of a capacitor case side wall through a cathode terminal passage, or is prolonged to the 封止 domain, connects two or more negative pole tabs, and prepares a negative pole contact button in the exterior of a case. A connector assembly performs electrical connection of an anode contact button, an anode tab, and a negative pole contact button and a negative pole tab. [Selection figure] Fig. 1
