Abstract

Systems and techniques that enable a user to selectively extend the time prior to providing an indication of power source depletion, e.g., allow an extended the recommended replacement time (RRT) prior to providing an elective replacement indication (ERI), are described. The user provides input, which may indicate an acceptable level of implantable medical device performance, e.g., that lesser performance for a period between a default RRT and an extended RRT is acceptable. In response to the input, the time until providing an RRT/ERI notification, or some other indication of depletion of the implantable medical device power source, may be extended.

Claims

1. An implantable medical device system comprising:

an implantable medical device comprising a power source, wherein at least one performance characteristic of the implantable medical device changes as the power source is consumed over time; and

a processor configured to;

receive user input indicating an acceptable level of performance of the implantable medical device with respect to the performance characteristic of the implantable medical device; and

determine a time for providing an indication regarding depletion of the power source to the user based on the user input.

2. The implantable medical device system of claim 1, wherein the processor is configured to determine a recommended replacement time for the implantable medical device as a function of the user indicated level of performance.

3. The implantable medical device system of claim 2, wherein the user input indicates that the user will accept a lower level of performance, and the processor is configured to extend the recommended replacement time based on the user input.

4. The implantable medical device system of claim 1, wherein the processor prompts the user to provide the input, wherein the prompt indicates a future level of performance of the implantable medical device with respect to the performance characteristic.

5. The implantable medical device system of claim 4, wherein the processor prompts the user regarding selecting a later time for providing the indication regarding depletion of the power source before an earlier time for providing the indication regarding depletion of the power source is reached.

6. The implantable medical device system of claim 4, wherein the processor prompts the user regarding selecting a later time for providing the indication regarding depletion of the power source in response to reaching an earlier time for providing the indication regarding depletion of the power source.

7. The implantable medical device system of claim 4, wherein the prompt prompts the user to select a level of performance of the implantable medical device with respect to the performance characteristic, and the user input comprises a selected level of performance.

8. The implantable medical device system of claim 1, wherein the performance characteristic of the implantable medical device comprises a charge time of a discharge capacitor of the implantable medical device.

9. The implantable medical device system of claim 8, wherein the implantable medical device discharges the discharge capacitor to deliver defibrillation therapy.

10. The implantable medical device system of claim 1, wherein the processor is configured to:

monitor the level of the performance characteristic of the implantable medical device; and

provide the indication regarding depletion of the power source when the performance characteristic of the implantable medical device no longer meets or exceeds the user-indicated acceptable level of performance.

11. The implantable medical device system of claim 1, wherein the implantable medical device comprises the processor.

12. The implantable medical device system of claim 1, further comprising an external user interface device that is configured to communicate with the implantable medical device and comprises the processor.

13. A method comprising:

receiving, by a processor, user input indicating an acceptable level of performance of an implantable medical device with respect to a performance characteristic of the implantable medical device, wherein the performance characteristic of the implantable medical device changes as a power source of the implantable medical device is consumed over time; and

determining, by the processor, a time for providing an indication regarding depletion of the power source to the user based on the user input.

14. The method of claim 13, wherein determining the time comprises determining a recommended replacement time for the implantable medical device as a function of the user indicated level of performance.

15. The method of claim 14, wherein the user input indicates that the user will accept a lower level of performance, and determining the recommended replacement time comprises extending the recommended replacement time based on the user input.

16. The method of claim 13, further comprising prompting the user to provide the input, wherein the prompt indicates a future level of performance of the implantable medical device with respect to the performance characteristic.

17. The method of claim 16, wherein prompting the user to provide the input comprises prompting the user to select a level of performance of the implantable medical device with respect to the performance characteristic, and wherein the user input comprises a selected level of performance.

18. The method of claim 13, wherein the performance characteristic of the implantable medical device comprises a charge time of a discharge capacitor of the implantable medical device.

19. The method of claim 13, further comprising:

monitoring the level of the performance characteristic of the implantable medical device; and

providing the indication regarding depletion of the power source when the performance characteristic of the implantable medical device no longer meets or exceeds the user-indicated acceptable level of performance.

20. A computer-readable storage medium comprising instructions that cause a programmable processor to:

receive user input indicating an acceptable level of performance of an implantable medical device with respect to a performance characteristic of the implantable medical device, wherein the performance characteristic of the implantable medical device changes as a power source of the implantable medical device is consumed over time; and

determine a time for providing an indication regarding depletion of the power source to the user based on the user input.
