    摘要: A body implanted device including a container having an opening through which extends an electrical feedthrough. The feedthrough includes a terminal of bio-stable material. A glass insulator is positioned around the terminal. The glass insulator is chosen from a CABAL-12 type composition or variation thereof. The terminal is comprised of a material which has thermal expansion characteristics compatible with the glass seal. For glass seals having a thermal expansion in the range of 6.8 to 8.0.times.10.sup.-6 in/in/.degree. C. the terminal is comprised of a thin layer of titanium metallurgically clad over niobium or tantalum. For glass seals having a thermal expansion in the range of 8.0 to 9.0.times.10.sup.-6 in/in/.degree. C. the terminal is comprised of platinum, platinum-iridium or alloys of either, or of pure titanium.

    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.
