摘要： An EMI/energy dissipating filter for an active implantable medical device (AIMD) is described. The filter comprises a first gold braze hermetically sealing the insulator to a ferrule that is configured to be mounted in an opening in a housing for the AIMD. A lead wire is hermetically sealed in a passageway through the insulator by a second gold braze. A circuit board substrate is disposed adjacent the insulator. A two-terminal chip capacitor disposed adjacent to the circuit board has an active metallization that is electrically connected to the active electrode plates and a ground metallization that is electrically connected to the ground electrode plates of the capacitor. A ground electrical path extends from the ground metallization of the chip capacitor to the ferrule. A conductive ground pin is electrically and mechanically connected to the ferrule. The ground path comprises an internal ground plate disposed within the circuit board substrate. The internal ground plate is electrically connected to the ground metallization of the chip capacitor and to either the ferrule or the ground pin connected to the ferrule. An active electrical path extends between the active metallization of the chip capacitor and the lead wire.

摘要： A three-terminal flat-through EMI/energy dissipating filter comprises an active electrode plate through which a circuit current passes between a first terminal and a second terminal, a first shield plate on a first side of the active electrode plate, and second shield plate on a second side of the active electrode plate opposite the first shield plate. The first and second shield plates are conductively coupled to a grounded third terminal. Both the effective capacitance area or overlapping surface area of the active electrode plate and the surrounding ground shield plates and the dielectric constant of the insulating layers between the active electrode plate and the ground shield plates is raised to achieve a higher capacitance value for the three-terminal flat-through capacitor.

摘要： An insulative feedthrough attachable to an active implantable medical device includes a feedthrough body having a material which is both electrically insulative, biocompatible and separates a body fluid side from a device side. A passageway is disposed through the feedthrough body. A composite conductor is disposed within the passageway and has a body fluid side metallic wire electrically conductive to a device side metallic wire. The body fluid side metallic wire extends from a first end disposed inside the passageway to a second end on the body fluid side. The device side metallic wire extends from a first end disposed inside the passageway to a second end on the device side. The body fluid side metallic wire is hermetically sealed to the feedthrough body. The body fluid side metallic wire is biocompatible and is not the same material as the device side metallic wire.

摘要： A hermetically sealed feedthrough for attachment to an active implantable medical device includes a dielectric substrate configured to be hermetically sealed to a ferrule or an AIMD housing. A via hole is disposed through the dielectric substrate from a body fluid side to a device side. A conductive fill is disposed within the via hole forming a filled via electrically conductive between the body fluid side and the device side. A conductive insert is at least partially disposed within the conductive fill. Then, the conductive fill and the conductive insert are co-fired with the dielectric substrate to form a hermetically sealed and electrically conductive pathway through the dielectric substrate between the body fluid side and the device side.
