ABSTRACT:
An apparatus and method for providing cryotherapy and controlled compression using a non-chlorofluorocarbon pressurized refrigerant supplied in a disposable canister, including a canister adapter, an inject valve which mates to the adapter, providing a steady flow rate of refrigerant to provide a predetermined cooling and a selectively initiated rapid flow of refrigerant to rapidly establish operating conditions, a conduit for connecting the inject valve and a maze fluid flow path in which the heat of vaporization of the refrigerant fluid cools an object in proximity to the maze, a bladder for accumulating vaporized refrigerant outside the maze and an exhaust valve having a predetermined relief pressure, venting refrigerant gas from the bladder to the atmosphere, thereby inflating the bladder with gaseous refrigerant to a specified pressure.
