Abstract
Low voltage conductors in a lead assembly share a lumen in a tube and are separated from adjacent conductors in the tube by an insulative layer. In an embodiment, low voltage conductors are combined with high voltage conductors. In another embodiment, low voltage conductors are combined with other low voltage conductors.
Claims26
