Abstract

A system and method for controlling a monitoring mode or treatment mode of an implantable medical device based on the detection of an external signal. The system and related method allow for more frequent monitoring of medical parameters at times where more frequent monitoring is necessary, such as during or after a dialysis session, with less frequent monitoring at other times, allowing for a more efficient medical device. The invention also allows for the frequency or mode of treatment by the implantable medical device, or the transmission of data from the implantable medical device to be controlled based on the external signal.

First claim

We claim:

1. A medical monitoring system, comprising:
an implantable medical device having one or more sensors configured to monitor data corresponding to at least one medical parameter;
an input in electronic communication with the implantable medical device, wherein the input is configured to receive a signal corresponding to at least one trigger; and
a dialysis machine configured to transmit the signal to the implantable medical device;
wherein the implantable medical device is configured to perform an action of changing a mode of monitoring the at least one medical parameter or of treating a medical condition associated with the at least one medical parameter based on the signal corresponding to the at least one trigger from a first mode to a second mode;
wherein the implantable medical device is configured to switch from either a high threshold mode to a low threshold mode or from a low threshold mode to a high threshold mode in response to the at least one trigger
wherein the trigger is a signal that a dialysis session is beginning or about to begin.

2. The medical monitoring system of claim 1 , further comprising a monitor in wireless communication with the implantable medical device, wherein the monitor is configured to receive and display the data corresponding to the at least one monitored medical parameter.

3. The medical monitoring system of claim 1 wherein the implantable medical device is configured to transmit the data to the dialysis machine, and the dialysis machine is configured to receive the data.

4. The medical monitoring system of claim 3 wherein the dialysis machine automatically sets at least one dialysis parameter based on the received data.

5. The medical monitoring system of claim 1 further comprising a memory component in communication with the implantable medical device; wherein the implantable medical device is configured to transmit the data to the memory component; and wherein the memory component is configured to receive and record the data.

6. The medical monitoring system of claim 5 wherein the memory component is part of the implantable medical device.

7. The medical monitoring system of claim 1 wherein the at least one medical parameter is selected from the group comprising impedance, fluid status indicators, ECG or EGM, heart rate, heart rate variability, blood pressure, patient activity, glucose level, potassium level, calcium level, magnesium level, sodium level, hematocrit level, urea level, CO 2 level, respiration, patient posture, and patient temperature.

8. The medical monitoring system of claim 1 wherein the trigger is proximity to the dialysis machine.

9. The medical monitoring system of claim 1 wherein the medical monitoring system is enclosed within another medical device.

10. The medical monitoring system of claim 1 wherein the implantable medical device is either:
(i) configured to always be capable of detecting the trigger;
(ii) configured to be capable of detecting the trigger at a set time;
(iii) configured to be capable of detecting the trigger at a set frequency; and/or
(iv) configured such that a user can cause the implantable medical device to become capable of detecting the trigger.

11. The medical monitoring system of claim 1 , wherein the mode of monitoring at least one medical parameter further comprises initiation of monitoring of a medical parameter or termination of the monitoring of a medical parameter.

12. A method, comprising the steps of:
establishing wireless communication between a dialysis machine and an implantable medical device;
receiving a trigger from the dialysis machine to the implantable medical device; and
performing an action of changing from a first data collection mode to a second data collection mode in the implantable medical device based on the trigger;
wherein the step of changing from a first data collection mode to a second data collection mode comprises changing from a high threshold mode to a low threshold mode or changing from a low threshold mode to a high threshold mode;
wherein the trigger is a signal that a dialysis session is beginning or about to begin.

13. The method of claim 12 , wherein the trigger is any one of proximity to the dialysis machine, an external communication message, a user trigger, or an algorithmic trigger.

14. The method of claim 12 , further comprising the step of transmitting data, control instructions, alerts, triggers, or programming between the dialysis machine and the implantable medical device via the wireless link.

15. The method of claim 14 wherein the data includes parameters for any one of impedance, fluid status indicators, ECG or EGM, heart rate, heart rate variability, blood pressure, patient activity, glucose level, potassium level, calcium level, magnesium level, sodium level, hematocrit level, urea level, CO 2 level, respiration, patient posture, patient temperature, and arrhythmia status.

16. The method of claim 12 further comprising performing an action of changing from the second monitoring mode to the first monitoring mode after a set period of time after receiving the trigger.

17. The method of claim 12 further comprising performing an action of changing from the second monitoring mode to the first monitoring mode after receiving a second trigger.

18. The system of claim 1 , wherein the implantable medical device is an implantable pacing device.

19. The system of claim 1 , wherein the first mode further comprises a high resolution or the low resolution mode and the second mode further comprises the high resolution mode or the low resolution mode.

20. The system of claim 1 , wherein either the first mode or the second mode further comprises a non-inhibited mode.
