1. A method for treating a spasticity in a limb of a patient, the method comprising:
inserting a cryogenic cooling needle through a skin surface, the needle comprising a proximal end, a distal end, and a lumen therebetween;
positioning the distal end of the cryogenic cooling needle within a target tissue proximate to a motor nerve associated with the spasticity in the limb of the patient by bending the needle outside a body of the patient to access the nerve along a plane of the target tissue, wherein the needle has varying stiffness at a proximal portion and a distal portion, wherein the motor nerve is in the limb of the patient; and
delivering a treatment cycle to the target tissue proximate to the nerve with the cryogenic cooling needle, the treatment cycle comprising a cooling phase wherein cooling fluid flows into the lumen so that liquid from the cooling fluid vaporizes within the lumen to provide cooling to the nerve so as to treat spasticity.
