Telemetry control for implantable medical devices
First Claim
1. An implantable medical device comprising:
- a sensor configured to sense at least one parameter;
a controller configured to receive data from the sensor; and
a telemetry module coupled to the controller for communication between the implantable medical device and an external device, the telemetry module having a configurable polling interval at which the telemetry module is activated for a period of time to detect whether a communication signal is being received from an external device, the polling interval of the telemetry module being configured at least partially based upon the at least one parameter sensed by the sensor, wherein the controller is configured with a first integration time for processing the sensed parameter to determine whether to reduce a length of the polling interval and a second integration time that is longer than the first integration time for processing the sensed parameter to determine whether to increase the length of the polling interval.

Abstract
An implantable medical device (IMD) and method are provided in which a telemetry module in the IMD includes a configurable polling interval at which the telemetry module is powered up from a low power inactive state to perform sniff operations for detecting whether communication signals are being received from an external device. The IMD includes at least one sensor for sensing at least one parameter, a controller receiving data from the sensor, and the telemetry module coupled to the controller for facilitating communication between the IMD and an external device. The polling interval of the telemetry module is configured based upon the parameter(s) sensed by the sensor, such that the polling interval is configured to conserve power consumption of the IMD. The polling interval is either decreased or increased to respectively increase or decrease the frequency of the sniff operations based on the parameters sensed at the IMD.
