Abstract
The present invention is directed to improved systems, devices, and methods for delivery of a cryogen to the skin of a patient for skin treatment. A cryospray device configured to deliver a cryogen to a patient's skin can include an applicator, a supply channel, and a nozzle assembly. The applicator can include a head portion, and the supply channel can extend through at least a portion of the head portion. The nozzle assembly can be coupled to the head portion and can be fluidly coupled to the supply channel. The nozzle assembly can include a linear array of orifices that are configured to direct a planar spray of the cryogen to cool an area of a skin tissue of the patient in a linear cooling treatment.
