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.
Claims24
A cryogenic probe comprising:
- a body releasably couplable to a handpiece and having at least one cryogenic treatment applicator fluidly connectable to a separate coolant supply device for providing coolant to the at least one cryogenic treatment applicator by way of a controllable valve;
- and
- an integrated circuit having a first processor and storing a tip descriptor, the integrated circuit being disposed within the body of the cryogenic probe, wherein the tip descriptor comprises operating instructions to control metering of the coolant to the cryogenic treatment applicator and wherein the integrated circuit is configured to send the tip descriptor including the operating instructions to control metering of the coolant to a second processor disposed in the handpiece for execution by the second processor.
A kit of cryogenic probes comprising:
- a plurality of cryogenic probes, each cryogenic probe releasably couplable to a handpiece and having a body with at least one cryogenic treatment applicator fluidly connectable to a separate coolant supply device for providing coolant to the at least one cryogenic treatment applicator,
- wherein at least one of the cryogenic probes includes a first processor comprising memory having instructional parameters for operating the coolant supply device and configured to send the instructional parameters to a second processor disposed in the handpiece for execution by the second processor, and wherein the first processor is configured to send the instructional parameters in response to a request from the second processor, and wherein the second processor initiates a timer for response by the first processor to the request.
A system for cryogenically treating tissue, the system comprising:
- a first type of probe having a first processor and memory storing a first type of tip descriptor, the first type of probe having at least one cryogenic treatment applicator;
- and
- a handpiece having a microprocessor control unit (MCU), the handpiece being releasably couplable and compatible with a plurality of different types of probes, wherein the first type of probe is fluidly couplable 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,
- wherein the MCU is configured to provide a first indicator when the first type of probe is usable and a second indicator different from the first indicator when the first type of probe is unusable, and wherein the MCU is configured to implement a first type of treatment protocol based on the first type of tip descriptor when the first probe is usable.
