1. A conductor for conducting a weak bio-electric signal from a first end of the conductor to a second end of the conductor, the weak bio-electric signal being obtained from a patient electrode connectable to said first end of the conductor, said conductor minimizing attenuation of the conducted, weak bio-electric signal while avoiding the inductive generation of currents in the conductor presenting a risk of injury to the patient when the conductor is used in an environment in which current-inducing electro-magnetic energy is present, said conductor comprising:

  • an electrically conductive member (6) extending between said first and second ends of the conductor, said electrically conductive member being formed of a solid, non-metallic, conductive material and exhibiting an impedance between said first and second ends in a range of 5 to 300 kilo-ohms;

    an insulating sheath member (7) surrounding the exterior of said electrically conductive member, said sheath member having insulating properties that are maintained when the sheath member is subjected to a voltage up to a predetermined magnitude; and

    a support member (8) extending between said first and second ends of said conductor and comprising a longitudinally substantially inelastic, flexible material.
