Abstract
A method in which a nerve associated with a spasticity in a limb of a patient may be identified. The cryogenic cooling needle may be inserted through a skin surface. The cryogenic cooling needle may be positioned to a target tissue such that the distal end of the cryogenic cooling needle is proximate to the nerve by bending the needle, wherein the needle has varying stiffness at a proximal portion and a distal portion. A treatment cycle may be delivered to a target tissue proximate to the nerve, the treatment cycle may comprise a cooling phase wherein cooling fluid flows into the lumen so that liquid from the cooling fluid flow vaporizes within the lumen to provide cooling to the nerve so as to treat spasticity.
