An implantable rod can be bent three-dimensionally in an automated system, which is especially useful for pre-surgical formation of implantable spinal rods. When local and / or global feedback processing accompanies a series of shaping steps automatically imposed on a rod or other article being shaped into three-dimensional form, formation time may be expedited compared to manual creation, and shapes difficult or impractical to create manually may be constructed simply.

Leads for chronic implantation in the brain or other anatomical targets utilize tubular stylet means which are external to the lead. The lead comprises a distal electrode terminal, a proximal connector terminal, and a conductor cable having a reinforced distal portion and a stepped outside diameter providing a shoulder which cooperates with the distal end of the external stylet means. The substantial stiffness of the external stylet allows implantation of the lead without a brain-entering cannula. A tubular stylet spacer is employed to minimize lead dislodgement due to disassembly and removal of the lead introduction tools. Externalized stylet allows the conductor cable to have a small outside diameter and a desirably short length. A method of terminating conductors to electrodes using inserts is suitable for very fine wires and stranded conductors. A reinforced electrode terminal construction enables robust small-dimensioned terminal and high localization accuracy when introduced with external stylet means.
