Patent ID: 7774071

Claim:
An electrically conducting lead comprising: an electrically-insulative elongate body; and an electrically conductive element, wound in an anticlockwise direction for a first length of said body and in a clockwise direction for a second length of said body, having first and second ends and comprising a plurality of layers, each said layer comprising a plurality of electrical conductors positioned within said conductive element such that a first length of each conductor is wound around said body in an anticlockwise direction and a second length of each conductor is wound around said body in a clockwise direction, wherein first ends of each of said conductors at said first end of said conductive element are correspondingly identifiable at said second end of said conductive element as second ends of each of said conductors, based on the corresponding position within said conductive element of each of said first and second ends of said conductors with respect to the positions of the other conductors.
