ABSTRACT:
A hermetic, leak-proof, corrosion resistant electrical feedthrough especially for use with implantable pulse generators. The feedthrough includes a titanium or niobium ferrule, an alumina insulator with a niobium braze area thereon positioned within the ferrule and sealed to the ferrule by a braze of gold at the braze area, electrical lead wires of niobium, tantalum, tungsten, molybdenum or alloys thereof extending through corresponding openings in the insulator, and a body of fusible glass joining and sealing each lead wire to the insulator.
