Claims
- 1. A method of calibrating a probe for insertion into the body of a subject, comprising:providing a probe having a programmable microcircuit and a distal end, the distal end including a functional portion adjacent to a distal tip of the distal end for performing diagnostic and/or therapeutic functions, the distal end also including a position signal generating device for generating signals used to determine the position of the probe within the subject's body; determining calibration data for the position signal generating device with respect to the distal tip of the probe; and programming the microcircuit so as to record the calibration data in the microcircuit.
- 2. A method in accordance with claim 1, and comprising encrypting a calibration code and programming the microcircuit therewith.
- 3. A method in accordance with claim 2 comprising:reading the encrypted code; and notifying a user of the probe if the encrypted code does not match a predetermined code.
- 4. A method in accordance with claim 3 comprising:reading the encrypted code; and ceasing operating of the probe if the encrypted code does not match a predetermined code.
- 5. A method in accordance with claim 1, wherein programming the microcircuit includes setting a usage record.
- 6. A method in accordance with claim 5, wherein the usage record is indicative of a permitted use date of the probe.
- 7. A method in accordance with claim 5, wherein the usage record is indicative of how many times the probe may be re-used.
- 8. A method in accordance with claim 5, wherein the usage record is indicative of a duration of time during which the probe may be operated.
- 9. A method in accordance with claim 5, wherein programming the microcircuit includes restricting access to the usage record, so that availability of the probe to a user thereof may be reduced, but not increased.
- 10. A method in accordance with claim 9, wherein restricting access to the usage record comprises allowing one or more bits in the record to be changed from a first value to a second value thereof, but not from the second value to the first value.
- 11. A method in accordance with claim 1, wherein restricting access to the usage record comprises setting a password.
- 12. A method in accordance with claim 1, wherein the calibration data relate to the position signal generating device, which generates signals responsive to the position or orientation of the probe.
- 13. A method in accordance with claim 12, wherein the signal generating device has a gain, and the calibration data include data relating to the gain of the device.
- 14. A method in accordance with claim 12, wherein the calibration data include data relating to an angular orientation of the signal generating device.
- 15. A method in accordance with claim 12, wherein the calibration data include date relating to a positional displacement of the signal generating device, relative to the probe.
- 16. A method for programming a probe for insertion into the body of a subject, the method comprising the steps of:providing a probe having a programmable microcircuit and a distal end, the distal end including a functional portion adjacent to a distal tip of the distal end for performing diagnostic and/or therapeutic functions, the distal end also including a position signal generating device for generating signals used to determine the position of the probe within the subject's body; and programming the microcircuit with an expiration date and time.
- 17. The method according to claim 16, including determining a pre-set interval for the expiration date and time based on the actual date and time when the probe is first used.
- 18. A method for programming and tracking usage of a probe for insertion into the body of a subject, the method comprising the steps of:providing a probe having a programmable microcircuit and a distal end, the distal end including a functional portion adjacent to a distal tip of the distal end for performing diagnostic and/or therapeutic functions, the distal end also including a position signal generating device for generating signals used to determine the position of the probe within the subject's body; programming the microcircuit with a number of times that the probe may be used; and tracking with the microcircuit the number of times that the probe is used.
- 19. The method according to claim 18, further comprising wherein the number of times defines a minimum value and preventing further operation of the probe upon reaching the minimum value.
- 20. The method according to claim 19, further comprising displaying a message to the user that the probe is unsuitable for further use upon reaching the minimum value.
- 21. A method for programming and tracking the usage of a probe for insertion into the body of a subject, the method comprising the steps of:providing a probe having a programmable microcircuit and a distal end, the distal end including a functional portion adjacent to a distal tip of the distal end for performing diagnostic and/or therapeutic functions, the distal end also including a position signal generating device for generating signals used to determine the position of the probe within the subject's body; storing a record in the microcircuit corresponding to a duration of use for the probe, the record including a minimum value; reducing the record for each use of the probe; and preventing further operation of the probe when the record reaches the minimum value.
