Abstract
Embodiments include cryogenic systems and methods for treating pain or spasm associated with a nerve of a patient. A target nerve may be located and a distal end of a cryogenic system needle may be inserted into a tissue at a desired location in proximity to the target nerve. The needle includes an outer lumen and an inner lumen extending distally within the outer lumen, the inner lumen including a distal opening that is open to the outer lumen. A cooling fluid may be delivered from a cooling fluid source to the needle via a fluidic pathway, the fluidic pathway including the cooling fluid source, the inner lumen, and the outer lumen, wherein a flow of the cooling fluid cools the needle so that the needle cools the target nerve at the desired location sufficiently such that the pain or spasm is inhibited.
