1. A method of cooling an area of skin tissue of a patient, the method comprising:
positioning a cryospray applicator to a position proximate to the area of skin tissue of the patient to be treated;
directing a planar spray of cryogen through a linear array of orifices of the cryospray applicator to cool the area of skin tissue of the patient in a line of cooling treatment to effect a treatment of the area of skin tissue; and
moving the cryospray applicator non-parallel to the line of cooling treatment while directing the planar spray of cryogen to provide a moving linear curtain of cooling treatment to cool the area of skin tissue of the patient and create a continuous treated area.
