Abstract

A method includes monitoring infection in proximity to a rechargeable implantable medical device; determining whether an event associated with recharging of the device has occurred; and blanking the monitoring if the event has occurred.

Claims

1. A method performed by an implantable medical device, comprising:

monitoring infection in proximity to a rechargeable implantable medical device;

determining whether an event associated with recharging of the device has occurred; and

blanking the monitoring if the event has occurred.

2. The method of claim 1, wherein monitoring infection comprises temperature.

3. The method of claim 1, wherein monitoring infection comprises one or more of sensing an indicator of infection, storing information regarding the sensed indicator, determining whether information regarding the sensed indicator is indicative of an infection, and issuing an alert if the if the sensed indicator is indicative of infection.

4. The method of claim 3, wherein blanking comprises refraining from issuing the alert.

5. The method of claim 3, wherein blanking comprises refraining from determining whether information regarding the sensed indicator is indicative of an infection.

6. The method of claim 3, wherein blanking comprises refraining from storing information regarding the sensed indicator.

7. The method of claim 3, wherein blanking comprises refraining from sensing information regarding the indicator.

8. The method of claim 1, wherein determining whether the event has occurred comprises receiving a signal from an external device.

9. The method of claim 8, wherein determining whether the event has occurred comprises detecting a change in temperature.

10. The method of claim 8, wherein determining whether the event has occurred comprises detecting current in a secondary recharge coil of the device.

11. The method of claim 1, further comprising reinitiating infection monitoring following the blanking.

12. The method of claim 11, wherein the reinitiating comprises resuming monitoring after completion of the recharging of the device.

13. The method of claim 12, further comprising detecting the completion of the recharging of the device.

14. The method of claim 13, wherein detecting the completion of the recharging of the device comprises receiving a signal from an external device.

15. The method of claim 13, wherein detecting the completion of the recharging of the device comprises detecting a change in temperature.

16. The method of claim 13, wherein detecting the completion of the recharging of the device comprises detecting current in a secondary recharge coil of the device.

17. The method of claim 13, further comprising determining whether a predetermined amount of time has elapsed prior to resuming the infection monitoring.

18. A computer readable medium containing instructions that when implemented cause an implantable rechargeable medical device to:

monitor infection in proximity to the device,

detect an event associated with recharging of the device; and

blank the monitoring during recharging of the device.

19. An implantable medical device comprising:

a rechargeable power source;

electronics operably coupled to the power source and configured to monitor an infection in proximity to the device;

a sensor operably coupled to the electronics and capable of monitoring an indicator of infection;

a computer readable medium according to claim 18 readable and executable by the electronics.
