1. A lead assembly comprising:
a lead body extending from a proximal end portion to a distal end portion, the lead body having at least one inner lumen and one or more exit lumens;
at least one cable disposed within at least a portion of the lead body, the at least one cable having at least two coiled electrode portions and non-electrode portions;
the non-electrode portions of the cable extending along within the inner lumen of the lead body, the at least two coiled electrode portions exiting through at least one of the exit lumen and coiled around an exterior portion of the lead body and forming electrodes; and
at least one non-electrode portion disposed between a first coiled electrode portion and a second coiled electrode portion, the first coiled electrode portion coiled in an opposite direction as the second coiled electrode portion.
