Patent ID: 8560084

Claim:
A biomedical conductor assembly adapted for at least partial insertion in a living body, the conductor assembly comprising: a plurality of first electrical conductors, each first electrical conductor being covered with an insulator; a plurality of second electrical conductors, at least one of the plurality of second electrical conductors including a plurality of un-insulated wires twisted in a ropelike configuration around a central axis to form a cable, each cable being covered with an insulator, the un-insulated wires being movable with respect to each other within the insulator, wherein the plurality of the first electrical conductors are helically wound in a first direction to form an inner coil with a lumen, and the plurality of the second electrical conductors are helically wound in a second opposite direction to form an outer coil around an outside of the inner coil and in direct physical contact with the inner coil, wherein the inner coil is substantially concentric with the outer coil; and an insulator covering the inner and outer coils.
