Abstract
A method for cryogenically treating tissue. A connection is detected between a probe having a disposable secure processor (DSP) to a handpiece having a master control unit (MCU) and a handpiece secure processor (HSP), the probe having at least one cryogenic treatment applicator. The probe is fluidly coupled to a closed coolant supply system within the handpiece via the connection. An authentication process is initiated between the DSP and the HSP using the MCU. As a result of the authentication process, one of at least two predetermined results is determined, the at least two predetermined results being that the probe is authorized and non-authorized.
