ABSTRACT:
A body implantable flexible lead assembly, adapted to transmit electrical pulses between a proximal end of the lead assembly and a distal end of the assembly to stimulate selected body tissue, includes a tubular, insulating housing connecting the proximal and distal ends of the assembly and having a central, longitudinal axis. At least two coiled, insulated conductors extend between the proximal and distal ends of the assembly for transmitting electrical signals, the coils of the at least two insulated conductors having substantially the same diameter. One of the coiled conductors is rotatable about the longitudinal axis relative to the other coiled conductor(s) and has a proximal end and a distal end. Last, a helix electrode is electrically connected to the distal end of the one coiled conductor for piercing the tissue to be stimulated, the one coiled conductor being adapted to extend or retract the helix electrode relative to the distal end of the assembly through rotation of the proximal end of the one coiled conductor.
