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.
Claims20
A system comprising:
- a probe having at least one cryogenic treatment applicator and a disposable secure processor (DSP);
- a handpiece removeably coupled to the probe and configured to provide cryogen coolant from a coolant supply system to the probe, the handpiece having a microcontroller unit (MCU) and a handpiece secure processor (HSP);
- wherein the MCU is configured to:
- detect connection of the probe to the handpiece;
- initiate an authentication process between the DSP and the HSP using the MCU;
- and
- as a result of the authentication process, determining one of at least two predetermined results, the at least two predetermined results comprising that the probe is authorized and non-authorized.
A system for cryogenically treating tissue, the system comprising:
- a first type of probe having a first processor and first memory storing a first type of tip descriptor, wherein the first type of probe has at least one of cryogenic treatment applicator configuration;
- a second type of probe having a second processor and second memory storing a second type of tip descriptor, wherein the second type of probe shares the same type of cryogenic treatment applicator configuration as the first type of probe;
- and
- a handpiece having a microcontroller unit (MCU), the handpiece being compatible with a plurality of different types of probes, the first and second type of probe each being fluidly couplable in sequence to a closed coolant supply system within the handpiece,
- wherein the first processor is configured to communicate the first type of tip descriptor to the MCU, and
- wherein the MCU is configured to implement a first type of treatment protocol based on the first type of tip descriptor,
- wherein the second processor is configured to communicate the second type of tip descriptor to the MCU, and
- wherein the MCU is configured to implement a second type of treatment protocol based on the second type of tip descriptor.
