Patent Images
1. A system, comprising:
- a remote monitoring device for an implantable medical device, includingan interface to a network; and
circuitry within the remote monitoring device to;
enable bidirectional wireless communication between the remote monitoring device and the implantable medical device via a telemetry link;
interrogate the implantable medical device over the telemetry link by initiating a communications session and collecting data transmitted from the implantable medical device in accordance with an interrogation schedule;
receive requests via the network interface to schedule interrogations of the implantable medical device in order to collect specified data;
combine interrogations scheduled to occur at or near the same time, as a result of the requests, into a single communications session;
withhold the combined interrogations until a specified time period for issuing pending requests has expired; and
override the withholding when a number of received requests satisfies a request number threshold.

Abstract
In a patient management system, a remote monitoring device interrogates an implantable device on an intermittent basis over a wireless telemetry link, with interrogations being performed either according to a programmed schedule or upon receiving a command to do so via the user interface or the network interface. Described is a system and method for optimizing, limiting, and/or monitoring an implantable device'"'"'s telemetry usage in order to avoid premature battery depletion and/or raise an alert if excessive battery depletion is beginning to occur.

14. A method by which a remote monitoring device interrogates an implantable medical device over a wireless telemetry link, comprising:
-
receiving requests via a network to schedule interrogations of the implantable medical device in order to collect specified data; combining interrogations scheduled to occur at or near the same time into a single communications session; interrogating the implantable medical device over the telemetry link by initiating a communications session and collecting data transmitted from the implantable medical device in accordance with an interrogation schedule including withholding the combined interrogations until a specified time period for issuing pending requests has expired; and overriding the withholding when a number of received requests satisfies a request number threshold. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
