Implantable lead for obstructive sleep apnea

An implantable lead configured to be placed near a nerve of a patient, comprising:

• an elongated shaft defining a longitudinal axis;
• a conductor coil disposed within an inner lumen of the elongated shaft and extending along the longitudinal axis, wherein the conductor coil comprises a plurality of conductive wires;
• and
• a plurality of electrodes disposed on a distal portion of the elongated shaft, each electrode comprising:
• an elongated electrode body extending from a proximal end to a distal end, wherein the elongated electrode body defines an outer surface and an inner surface in contact with the inner lumen, and wherein the elongated electrode body defines one or more grooves extending from the inner lumen towards the outer surface;
• an opening configured to retain a respective conductive wire of the plurality of conductive wires extending from the conductor coil,
• wherein each electrode of the plurality of electrodes is electrically connected to the conductor coil via the respective conductive wire, and wherein each electrode of the plurality of electrodes is affixed to a first flexible portion at the distal end and to a second flexible portion at the proximal end.
