Lumbar Injectrode Feasibility Evaluation

The PNS Injectrode F1 is a flexible conductor that conforms to the shape of a peripheral nerve and patient anatomy. The device is approximately 1 mm in overall diameter and is provided in lengths of 9 or 10 cm. The device is placed in a minimally invasive procedure via a standard 18g needle. The stimulating end of the device is placed in close proximity to the lumbar medial branch nerve with a collector end left subcutaneously. Electrical stimulation is provided via an externally placed patch electrode connected to the provided external pulse generator over the collector end of the device. Transcutaneous electrical stimulation will occur prior to device placement, on Day 0 after device placement, and on Day 25 prior to device removal. Minimally invasive removal is completed by a small incision and forceps using standard medical procedures and equipment.
