Implantable conductor coil formed from cabled composite wire
First Claim
1. A biomedical conductor device, for at least partial insertion in a human or animal body, comprising:
- at least one helical coil formed from at least one electrical cable, said cable being formed from a plurality of wires twisted in a ropelike configuration with at least a part of said wires being helically wound around a central axis of said cable so that the wires belonging to said cable are held together and are movable with respect to each other within certain limits; and
each of said wires comprising a core of a first material, said core being surrounded by a covering of a second material over the length of said core, wherein all adjacent wires belonging to the same cable are in uninsulated contact with each other.

Abstract
An implantable lead conductor comprises at least one helical coil formed from at least one electrical cable. Each cable is formed from several wires twisted in a ropelike configuration with at least some of the wires being helically wound around a central axis of the cable. Each wire is a composite comprising a core of a first material and a coveting of a second material, with all adjacent wires belonging to the same cable in uninsulated contact with each other. Preferably, the core material is highly conductive, and the covering material is strong and biocompatible. The helical coil has a lumen for insertion of a stylet to facilitate insertion through a vein.
