Abstract
A hermetically sealed filtered feedthrough for an active implantable medical device includes a first conductive leadwire extending from a first end to a second end, the first leadwire second end extending outwardly beyond the device side of an insulator hermetically sealed to a ferrule for the feedthrough. A circuit board supporting a chip capacitor is disposed adjacent to a device side of the insulator and has a circuit board passageway. The first leadwire first end resides in the circuit board passageway. A second conductive leadwire on the device side has a second leadwire first end disposed in the circuit board passageway with a second leadwire second end extending outwardly beyond the circuit board to be connectable to AIMD internal electronics. The second leadwire first end is connected to the first leadwire first end and a capacitor internal metallization in the circuit board passageway. The circuit board further comprises a ground electrode plate that is connected to the ground termination of the chip capacitor and to the ferrule.
