1. A device implantable in a living body for the electrical stimulation of a single nerve, said device comprising:

  • a. a relatively thin strip of flexible, electrically insulating material that is inert to body tissues and fluids;

    b. at least two substantially flat, electrically conductive electrode means secured to a surface of said strip, said electrode means comprising cup-shaped noble metal meMbers with the edge of said cup-shaped members bearing against said strip of insulating material;

    c. a staple for securing each said electrode means to said strip of insulating material, said staple being welded to the inside of said respective cup-shaped member, said staples having legs crimped against the side of said strip of insulating material that is opposite to that to which said cup-shaped members are secured;

    d. first conductive lead means electrically and physically coupled to said electrode means and welded to said staples, said first conductive lead means being of relatively high tensile strength; and

    e. second conductive lead means secured to each said high tensile strength first lead means, said second conductive lead means comprising bundles of stainless steel filaments in the order of twelve microns diameter, said bundles containing from 50 to 450 filaments.
