<p>A living body insertion electrode lead so designed that an omen for breakage of the electrode lead can be detected and reported in early stages before complete breakage; and a living body insertion medical instrument using the same, which can be used more safely. That is, a living body insertion electrode lead including parallel combinations of conductor wires (23, 27) of higher electric resistance and conductor wires (40, 44) of lower electric resistance is capable of detecting and reporting a change in the electric resistance of the living body insertion electrode lead at a point of time when one of the lower-strength conductor wires (23, 27) breaks; therefore, an omen for breakage of the entire living body insertion electrode lead can be found.</p> |
