Abstract

A system is described for removing heat from a subject'"'"'s subcutaneous lipid-rich regions, such as tissues, organs, cells, and so forth. In various embodiments, the system includes a controller, a computing device, a data acquisition device, a chiller, and one or more applicators. The system can employ these components to receive a selection of a treatment profile and apply the selected treatment using an applicator. The treatment profile may be received from a patient protection device that connects to an applicator.

Claims

1. A method performed by a system for cooling a subcutaneous lipid-rich region of a subject, the method comprising:

receiving an indication that a usage metering component has connected to the system;

retrieving, from the usage metering component, a limit value, and a use indicator;

determining, based on the use indicator and the limit value, whether the usage metering component has expired;

when the usage metering component has expired, preventing an applicator of the system from cooling the subcutaneous lipid-rich region; and

when the usage metering component has not expired, allowing the applicator to cool the subcutaneous lipid-rich region.

2. The method of claim 1 wherein the indication that the usage metering component has connected to the system is received mechanically.

3. The method of claim 1, further comprising retrieving, from the usage metering component, a limit type indicating that the limit value is a count, wherein the use indicator includes a use count that indicates a number of times that the usage metering component has been used, the usage metering component having expired when the use count is equal to the limit value.

4. The method of claim 1, further comprising retrieving, from the usage metering component, a limit type indicating that the limit value is a time, the usage metering component having expired when a present time is after the limit value.

5. The method of claim 1, further comprising retrieving, from the usage metering component, a limit type indicating that the limit value is a duration, wherein the use indicator includes a start time that indicates a time at which the usage metering component was first used, the usage metering component having expired when a difference between a present time and the start time exceeds the limit value.

6. The method of claim 1, further comprising retrieving, from the usage metering component, a limit type indicating that the limit value is a duration, wherein the use indicator includes a stop time that indicates a time at which the usage metering component stopped being used, the usage metering component having expired when a difference between a present time and the stop time exceeds the limit value.

7. The method of claim 1 wherein preventing the applicator from cooling the subcutaneous lipid-rich region includes ignoring commands to apply a treatment.

8. The method of claim 1 wherein:

the limit value indicates a number of uses;

the use indicator includes a use value that indicates an actual number of uses; and

determining whether the usage metering component has expired includes;

determining that the usage metering component has expired because the use value is equal to the limit value, or

determining that the usage metering component has not expired because the use value is less than the limit value.

9. The method of claim 1 wherein:

the limit value indicates a time at which the usage metering component expires or expired; and

determining whether the usage metering component has expired includes;

determining that the usage metering component has expired because a present time is after the limit value, or

determining that the usage metering component has not expired because the present time is before the limit value.

10. The method of claim 1, further comprising authenticating the usage metering component.

11. The method of claim 1, further comprising establishing an encrypted communications channel with the usage metering component.

12. The method of claim 1 wherein:

the usage metering component includes a secure processor; and

retrieving the limit value and use indicator includes retrieving the limit value and use indicator from the secure processor.

13. The method of claim 1 wherein:

the usage metering component includes a smartcard device; and

retrieving the limit value and use indicator includes retrieving the limit value and use indicator from the smartcard device.

14. The method of claim 1, further comprising preventing the applicator from cooling the subcutaneous lipid-rich region before receiving the indication that the usage metering component has connected to the system.

15. The method of claim 1, further comprising retrieving, from the usage metering component, an identifier.

16. The method of claim 15, further comprising comparing the identifier to a list of expired identifiers.

17. The method of claim 16 wherein determining whether the usage metering component has expired includes determining whether the usage metering component has expired based on a result of comparing the identifier to the list of expired identifiers.

18. The method of claim 15, further comprising comparing the identifier to a list of invalid identifiers.

19. The method of claim 18, further comprising:

determining whether the usage metering component is invalid based on a result of comparing the identifier to the list of invalid identifiers;

when the usage metering component is invalid, preventing the applicator from cooling the subcutaneous lipid-rich region; and

when the usage metering component is not invalid, allowing the applicator to cool the subcutaneous lipid-rich region.
