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 centerless grinding method of finishing feedthrough pins and corresponding devices for use in implantable medical devices and for components such as batteries in implantable medical devices is disclosed. The method provides certain advantages, including the elimination of longitudinal anomalies in drawn wire to thereby improve the hermeticity of implantable medical devices. In one of the preferred methods, the surface of an over-size medical grade wire having a known anomaly depth is centerless ground using an abrasive wheel and suitable coolant to a layer past which those anomalies disappear.

摘要： A method for making a seal between a sealing glass and titanium by forming a nitride layer on the titanium and then sealing the glass to the nitrided titanium. The formation of the nitride layer can be accomplished by the steps of placing the titanium in a substantially oxygen-free atmosphere comprising a major amount of an inert gas and a minor amount of nitrogen and heating the titanium in that atmosphere to a temperature of at least 300.degree. C. The method allows for the formation of the nitride layer and the glass seal in a single operation. The method works well in the manufacture of feedthroughs with conventional processing equipment.
