Phased deactivation of functionality in implantable medical device systems
Embodiments of the invention are related to systems for interfacing with implantable medical devices, amongst other things. In an embodiment, the invention includes an external medical system including a processor and a telemetry circuit in communication with the processor, the processor configured to communicate with an implanted medical device. The system can be configured to query a system user after a first period of time in which indicators of system use are not detected. The system can be further configured to deactivate one or more data transmission features of the implanted medical device after a second period of time in which one or more indicators of system use are not detected. Other embodiments are also included herein.
1. An external medical system comprising:
a processor; and
a telemetry circuit in communication with the processor configured to communicate with an implanted medical device;
a timer in communication with the processor to measure time periods; and
a video output in communication with the processor;
the external medical system configured to query a system user through the video output after a first period of time in which indicators of system use are not detected by the processor,
wherein the first period of time expires prematurely upon detection by the processor of the distance between the implanted medical device and the external medical system exceeding a threshold distance,
the processor configured to deactivate one or more data transmission features of the implanted medical device after a second period of time in which one or more indicators of system use are not detected.
2. The external medical system of claim 1 , the system user query regarding the identity of the patient.
3. The external medical system of claim 1 , the indicators of system use comprising system user input.
4. The external medical system of claim 1 , the one or more data transmission features comprising transmission of real-time data from the implanted medical device.
5. The external medical system of claim 1 , wherein the processor is further configured to deactivate additional data transmission features of the implanted medical device after a third period of time in which indicators of system use are not detected.
6. The external medical system of claim 5 , wherein the third period of time ends simultaneously with the end of the second period of time.
7. The external medical system of claim 5 , the additional data transmission features comprising long-range telemetry functionality.
8. The external medical system of claim 1 , the system configured to deactivate transmission of real-time data from the implanted medical device after a second period of time in which one or more indicators of system use are not detected; and deactivate long-range telemetry functionality of the implanted medical device after a third period of time in which one or more indicators of system use are not detected.
9. The external medical system of claim 1 , the first period of time comprising between about 30 seconds and about 30 minutes.
10. The external medical system of claim 1 , wherein the second period of time begins after the first period of time has elapsed.
11. The external medical system of claim 1 , the second period of time comprising between about 2 minutes and about 60 minutes.
12. The external medical system of claim 1 , wherein the third period of time begins after the second period of time has elapsed.
13. The external medical system of claim 1 , the third period of time comprising between about 10 minutes and about 2 hours.
