摘要： An EMI filter capacitor assembly utilizes biocompatible and non-migratable materials to adapt electronic components for direct body fluid exposure. The assembly includes a capacitor having first and second sets of electrode plates which are constructed of non-migratable biocompatible material. A conductive hermetic terminal of non-migratable and biocompatible material adjacent to the capacitor is conductively coupled to the second set of electrode plates. One or more conductive terminal pins having at least an outer surface of non-migratable and biocompatible material are conductively coupled to the first set of electrode plates, while extending through the hermetic terminal in non-conductive relation. The terminal pins may be in direct contact with the first set of electrode plates, or in contact with a termination surface of conductive connection material. The termination surface is also constructed of non-migratable and biocompatible materials. Layers of glass may be disposed over surfaces of the assembly, including the capacitor.

摘要： An EMI filtered connector includes a plurality of conductive terminal pins, a grounded conductive connector housing through which the terminal pins pass in non-conductive relation, and an array of feedthrough filter capacitors. Each of the feedthrough filtered capacitors has a distinct first set of electrode plates, a non-distinct second set of electrode plates, and a first passageway through which a respective terminal pin extends in conductive relation with the first set of electrode plates. At least one ground lead is conductively coupled to the conductive connector housing and extends into a second passageway through the array of feedthrough filter capacitors in conductive relation with the second set of electrode plates. An insulator is disposed in or adjacent to the connector for mounting the conductive terminal pins for passage through the conductive connector with the conductive terminal pins and the connector in non-conductive relation. The outer peripheral surface of the array of feedthrough filter capacitors is non-conductive.

摘要： A feedthrough filter capacitor assembly includes a conductive terminal pin which extends through a first passageway of a capacitor in conductive relation with a first set of electrode plates, and through a conductive ground plane and an insulator in non-conductive relation. The insulator includes ground plates conductively coupled to the ferrule. A second set of electrode plates of the capacitor are conductively coupled to the insulator ground plates, such as by a ground pin extending through the capacitor in relation with the second set of electrode plates, and at least partially extending through a second passageway of the insulator in conductive relation with the ground plates. In this manner, the exterior electrical/mechanical connection between the capacitor and ground plane or other ground member is eliminated.

摘要： A feedthrough terminal assembly for an active implantable medical device utilizes an insert to establish a reliable electrical connection between capacitor electrode plates, via inner surface metallization of a capacitor aperture, and an associated terminal pin 10, which passes at least partially therethrough. The inserts are preferably resiliently flexible, such as a spring, to establish this connection. The insert also serves to establish a mechanical connection between the capacitor and the terminal pin.

摘要： An insulative shield is co-bonded to the top of a ceramic capacitor in a feedthrough terminal assembly on an active implantable medical device. The insulative shield is a thin substrate that provides protection against damage and degradation of the feedthrough capacitor and/or its conformal coating from heat, splatter or debris resulting from the electromechanical connection of components during construction of the assembly. Laser welding, thermal or ultrasonic bonding, soldering, brazing or related lead attachment techniques can create such heat, splatter or debris. In a preferred embodiment, the insulative shield is co-bonded using the capacitor's own conformal coating.

摘要： A band stop filter is provided for a lead wire of an active medical device (AMD). The band stop filter includes a capacitor in parallel with an inductor. The parallel capacitor and inductor are placed in series with the lead wire of the AMD, wherein values of capacitance and inductance are selected such that the band stop filter is resonant at a selected frequency. The Q of the inductor may be relatively maximized and the Q of the capacitor may be relatively minimized to reduce the overall Q of the band stop filter to attenuate current flow through the lead wire along a range of selected frequencies. In a preferred form, the band stop filter is integrated into a TIP and/or RING electrode for an active implantable medical device.
