ABSTRACT:
An implantable lead has conductors wound in a multi-pole helix. The conductors are individually insulated by a first insulating material and the insulated conductors are embedded in, and axially separated from each other by a second tube-formed insulating material. The inner opening of the tube receives a helically wound stylet guide coil which may also be a multi-pole conductor arrangement. The conductors may be helically wound, multi-filament wires. Preferably, all helically wound arrangements in the lead are wound in the same direction so that the lead is still when rotating it in one direction and flexible when rotating it the other way.
