Abstract: The electrode having a tubular indulative body accomodating an electrical supply lead made as a coil spring rigidly coupled to distal and contact heads, both accomodated in the body at opposite ends thereof. The opposite end portions of the coil spring have a length not exceeding twice the distance from the place of contact of the contact head with the interior portion of the organ, to the place where the electrode emerges from said organ, the coils of the coil spring are spaced in a close proximity to one another. On a middle portion of the coil spring the coils are spaced with a pitch that provides for a longitudinal stability of the electrode while being passed via a transvenous route to be implanted in an organ involved.

Abstract: An electrical conductor for implantation into human body is made as a braid woven of fibers and enclosed into an insulating sheath. Each fiber is a tube made of a high-strength corrosion-proof nontoxic alloy filled with a highly conductive alloy or metal.
