1. An implantable lead device for conducting electrical signals comprising:
a distal end and a proximal end;
one or more homogeneous continuous conductive polymeric material elements supported by one or more segmented non-conductive polymeric materials; and
one or more isolated conductive pathways defined by an arrangement of the one or more homogeneous continuous conductive polymeric material elements and the one or more segmented non-conductive polymeric materials, wherein the one or more isolated conductive pathways transition to one or more non-isolated conductive areas for electrical dispersion or electrical reception,
wherein the one or more homogeneous continuous conductive polymeric material elements are juxtaposed contiguously with the one or more segmented non-conductive polymeric materials via additive manufacturing across more than three planes of direction, thereby providing anisotropic strength with no resulting bisection of conductivity.
