1. A method of forming a lead for implantation comprising:
forming a distal end assembly;
forming a proximal end assembly; and
forming a flexible circuit coupling the distal end assembly to the proximal end assembly;
wherein the distal end assembly, the proximal end assembly and the flexible circuit are formed over an inner member;
placing an outer member over the combination of the distal end assembly, the proximal end assembly and the flexible circuit; and
fusing both the inner member and the outer member to the flexible circuit, between the distal end assembly and the proximal end assembly at discrete locations along the lead;
wherein fusing the inner and outer members to the flexible circuit includes reflowing the inner and outer members such that materials of the inner and outer members and the flexible circuit are bonded together along the length of the lead between the distal end assembly and the proximal end assembly, and wherein non-fused portions of the inner member and the outer member between fused ends are free to move relative to each other.
