Claim 12:
13. A method for insertion of a lead for temporary stimulation of a peripheral nerve, the method comprising:
inserting into an electrical stimulation assembly into a patient proximate to a stimulation target, wherein the electrical stimulation assembly comprises:
a lead ribbon comprising:
a substantially flat lead ribbon substrate extending in a first plane when in an unwound state;
at least one trace running along a length of the lead ribbon substrate between a lead ribbon proximal end to a lead ribbon distal end;
at least one electrode disposed at the lead ribbon distal end and in electrical communication with the at least one trace;
at least one exposed electrical stimulation pad disposed at the lead ribbon proximal end and in electrical communication with the at least one trace; and,
a plurality of fixation members extending in the first plane form at least a first edge of the lead ribbon substrate when the lead ribbon substrate is in the unwound state, wherein the lead ribbon is wrapped around a longitudinal axis such that an exposed surface of at least one electrical stimulation pad is oriented radially outward relative to the longitudinal axis; and,

a hollow needle, in which the lead ribbon is wrapped around the longitudinal axis;

advancing the longitudinal axis to push the lead ribbon wrapped around the longitudinal axis out of a tip of the hollow needle to effectuate springing open of the lead ribbon to catch surrounding tissue;
sliding the hollow needle out from the surrounding tissue and separating the hollow needle from the lead ribbon;
expanding the lead ribbon radially outward such that the plurality of fixation members engages the surrounding tissue; and,
pulling the lead ribbon proximal end to unwind the lead ribbon such that the plurality of fixation members disengage from the tissue.
