摘要： The socket (100) has an insulator (122) with an opening for a socket pin (130), which is hermetically sealed by the insulator. A conductive metal ring (120) seals the outer insulator surface. A filter element fits over the insulator between the socket pin and the metal ring and is electrically connected to them. A non-conducting spacer is arranged over the socket pin to insulate the lower filter element surface and separate it from the insulator. A non-conducting spacer inside an inner space (140) between the filter element and the insulator is arranged over the socket pin to insulate the lower filter element surface and separate it from the insulator. Devices are arranged to permit gas to pass out of the inner space to the outer side of the socket. Leak test gas flows under the lower insulator surface and through defects in the insulator to the filter element, to determine if the insulator is not hermetically sealed. An Independent claim is included for filtered socket array.

摘要： A capacitive filter feedthrough assembly and method of making the same are disclosed for shielding an implantable medical device such as pacemaker or defibrillator from electromagnetic interference or noise. A ferrule is adapted for mounting onto a conductive device housing by welding, soldering, brazing or gluing, and supports a terminal pin for feedthrough passage to a housing interior. A capacitive filter is mounted at the inboard side of a device housing, with capacitive filter electrode plate sets coupled respectively to the housing and the terminal pin by an electrically conductive combination of solder and brazing. In one embodiment of the invention, multiple capacitive filters are provided in an array within a common base structure, where each capacitive filter is associated with a respective terminal pin.

摘要： Lecktestgeeignete, gefilterte elektrische Durchführung (100) mit: einem Durchführungsleiter; einem den Durchführungsleiter umgebenden Isolator (122) mit einer oberen Innenfläche; einem den Isolator (122) umgebenden, leitenden Metallring (120); einem oberhalb der Innenfläche des Isolators angeordneten, scheibenförmigen Filterelement, wobei das Filterelement eine sich zwischen einer oberen und einer unteren Oberfläche des Filterelements erstreckende Durchtrittsöffnung aufweist, die den Durchführungsleiter aufnimmt, und wobei das Filterelement eine äußere Randfläche aufweist, die sich zwischen der oberen und der unteren Fläche des Filterelements erstreckt und mit dem Metallring (120) leitend verbunden ist; einem vorgeformten, nicht-leitenden Abstandhalter (124), der zwischen die untere Fläche des Filterelements und die obere Innenfläche des Isolators und um den Durchführungsleiter eingesetzt ist; und Mitteln zum Bereitstellen eines Gasdurchganges, der sich von der oberen Fläche des Isolators nach außerhalb der Durchführung (100) erstreckt und an dem Filterelement sowie dem vorgeformten, nicht-leitenden Abstandhalter (124) vorbeiführt, wobei an der unteren Isolatoroberfläche angelegtes Lecktestgas, welches durch Defekte in dem Isolator (122) durchtritt, ausgehend von dem Abstandhalter (124) durch den an dem Abstandhalter (124) und dem an dem Filterelement vorbeiführenden Gasdurchlass leitbar ist, um festzustellen, dass der Isolator (122) nicht hermetisch abgedichtet ist.

摘要： The electrical lead-through assembly for an implant, comprises a bush (10) in a biocompatible, metallic material, and an insulating ceramic bush with a conductive, similarly-metallic pin (30) passing through. Biocompatible, conductive hard-soldered internal connections (65) are made, forming a seal, and further metals and alloys are proposed for this purpose. A ceramic capacitative filter (50) has an opening (35) with an electrical terminal clamp inside, with a further clamp provided on the filter external surface, and a further soft solder internal connection (55) is detailed, proposing a wide variety of suitable metallic materials. Further hard and soft solder bonds are described, and the capacitative filter damps electromagnetic interference, when installed in an implant.
