摘要： A lead may comprise a multiple filar wire comprising an inner core, an inner layer and an outer layer, where a portion of the inner layer is wound in a first orientation and the inner layer comprises a first number of filars of wire and where a portion of the outer layer is wound in a second orientation opposite the first orientation and the outer layer comprises a second number of filars of wire, the second number of filars of wire being greater than the first number of filars of wire. The lead may also comprise insulation covering a portion of the multiple filar wire, the portion of the multiple filar wire and the insulation comprising a helical coil structure wound in the first orientation and an anchor formed by the inner core, inner layer and outer layer extending away from the portion of the multiple filar wire, wherein the anchor comprises no helical coil structure.
