Pain Management Using Cryogenic Remodeling

Embodiments include methods and systems for treating back pain associated with a nerve. A needle of a cryogenic system may be inserted beneath a skin surface. The needle may include an electrically conducting structure at least partially surrounded by an electrical insulator for conducting electrical energy. The needle may include an outer lumen and an inner lumen extending distally within the outer lumen, the inner lumen include a distal opening open to the outer lumen. The needle may be positioned at a desired location in proximity to the nerve, and a cooling therapy including cooling cycles and thawing periods may be performed to cool tissue at the desired location. The cooling therapy may sufficiently reduce the back pain.
