Automatic parameter status on an implantable medical device system
First Claim
1. A method for monitoring a physiological parameter of a patient detected by an implantable medical device system comprising an implantable medical device, an external device and a processor configured to perform the method, comprising the steps of:
- monitoring the physiological parameter with the implantable medical device to determine if the physiological parameter exceeds an alert threshold and if the physiological parameter returns to a non-alert level;
if the physiological parameter exceeds an alert threshold;
scheduling a series of interrogation sessions between the implantable medical device and the external device to occur at predetermined time intervals;
transmitting data corresponding to the physiological parameter from the implantable medical device to the external device; and
continuing monitoring the physiological parameter with the implantable medical device;
thenif the physiological parameter has returned to a non-alert level;
automatically canceling at least one pending scheduled interrogation session of the series of interrogation sessions; and
automatically returning to the monitoring the physiological parameter with the implantable medical device; and
initiating transmitting data step by the external device “
waking up”
the implantable medical device.

Abstract
A method and apparatus for providing status of a parameter that includes detecting an alert level of a parameter monitored by an implanted medical device, transmitting data corresponding to the detected alert level from the implanted medical device to an external monitor, scheduling a follow-up interrogation session after receiving transmitted data corresponding to the detected alert level, and retrieving updated data from the implanted medical device corresponding to the monitored parameter during the follow-up interrogation session.
