Claim 0:
1. A method of fabricating a stimulation lead for electrical stimulation of tissue of a patient, the method comprising:
providing a paddle structure adapted to be implanted adjacent neural tissue for electrical stimulation, the paddle structure comprising a flexible polymer body;
providing electrodes arranged in a multi-dimensional pattern and positioned along a contact side of the flexible polymer body;
providing a plurality of sets of microtubes on the flexible polymer body, each microtube in the plurality of sets of microtubes having an inner lumen;
providing a lead body comprising conductor wires extending between proximal and distal ends of the lead body;
routing the conductor wires through the inner lumens of the microtubes of the plurality of sets of microtubes; and
electrically coupling the conductor wires that are within the microtubes to the electrodes, wherein the flexible polymer body of the paddle structure flexes transversely about its longitudinal axis and the plurality of sets of microtubes are arranged generally parallel to the longitudinal axis,
wherein a first backing layer holds a first plurality of the conductor wires side-by-side and a second backing layer holds a second plurality of the conductor wires side-by-side, the first and second backing layers projecting from the lead body in a splayed configuration.
