    Abstract: A feedthrough filter capacitor assembly for use in active implantable medical devices and a related process for manufacturing a monolithic ceramic capacitor utilizing dielectric materials having a dielectric constant greater than 7000, and preferably in the range of 8500 to 22,000. In the manufacture of the monolithic ceramic capacitor, one or more Curie point shifters and/or other dopants are added to the dielectric material to optimize the dielectric constant at the human body temperature of 37° C. For manufacturing purposes, dopants may be added to the dielectric material to broaden the Curie point peak or point of maximum dielectric constant thereof. The effect is that when such capacitors and terminal assemblies are utilized in a high-voltage defibrillator circuit of an implantable medical device, the dielectric material is optimized so that during the delivery of high-voltage electrical energy, capacitance value of the capacitor drops substantially.

    Abstract: A chip capacitor is conductively coupled to spaced-apart (i.e., non-conductively coupled) circuit traces of an integrated circuit to provide a four terminal network. The chip capacitor includes a casing of dielectric material having first and second sets of electrode plates disposed therein, a first conductive lead frame which is conductively coupled to the first set of electrode plates, and a second conductive lead frame which is conductively coupled to the second set of electrode plates. The first and second lead frames are, in turn, conductively coupled to the circuit traces so as to route the output (or input) current of an electronic device through the capacitor.

    Abstract: An integrated electromagnetic interference (EMI) filter capacitor and DC blocking capacitor is provided in a single monolithic casing of ceramic dielectric material. First and second sets of electrode plates are disposed within the monolithic casing to form the DC blocking capacitor, and ground electrode plates are disposed between selected portions of the first and second sets of electrode plates to form the EMI filter. In several of the embodiments, the first and second sets of electrode plates form a plurality of distinct DC blocking capacitors. The ground electrode plates cooperatively form, with the first and second sets of electrode plates, EMI filters for each of the distinct DC blocking capacitors. Discontinuous lead wires may be provided which extend at least partially into the casing, wherein a first segment of the lead wire is conductively coupled to the first set of electrode plates, and a second set of the lead wire is conductively coupled to the second set of electrode plates. Grounded shields also may be co-planarly disposed between adjacent components of the first and second sets of electrode plates to reduce cross-talk therebetween.

    Abstract: An EMI filter feedthrough terminal assembly includes at least one conductive terminal pin, a feedthrough filter capacitor which has a passageway through which the terminal pin extends, and a conductive substrate through which the terminal pin passes in non-conductive relation. The conductive substrate includes a capture flange having a height that is less than an axial thickness of the capacitor and which is configured to at least partially surround an outer periphery of the capacitor. The height of the capture flange is preferably one-quarter to three-quarters of the axial thickness of the capacitor. A first set of capacitor electrodeplates is conductively coupled to the terminal pin, and a second set of electrode plates is conductively coupled to the capture flange by means of a thermal-setting conductive material disposed between the outer periphery of the capacitor and the capture flange. A related process is provided for manufacturing an EMI filter feedthrough terminal assembly that advantageously utilizes the capture flange.

    Abstract: An integrated hermetically sealed feedthrough capacitor filter assembly is provided for the shielding and decoupling of a conductive terminal pin or lead of the type used, for example, in an implantable medical device such as a cardiac pacemaker or cardioverter defibrillator against passage of external interference signals, such as caused by digital cellular phones. The simplified feedthrough assembly described herein eliminates the traditional terminal pin subassembly. In this novel approach, the ceramic feedthrough capacitor itself forms a hermetic seal with a conductive pacemaker housing to which it is mounted by welding or brazing. The feedthrough capacitor is configured such that its internal electrodes are not exposed to body fluids, with capacitor electrode plate sets coupled respectively to a conductive ferrule, pin or housing (which may be grounded) and to the non-grounded, or active, terminal pin(s) by conductive adhesive, soldering, brazing, welding or the like. In one preferred form, multiple feedthrough filter capacitors are provided in a substantially coplanar array within a common base structure, with each capacitor in association with a respective terminal pin.
