TELEMETRY CONTROL FOR IMPLANTABLE MEDICAL DEVICES

摘要

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.
