摘要:
An implantable medical device comprises a near field telemetry module to wirelessly receive first information into the IMD, a far field telemetry module to wirelessly receive second information into the IMD, and a processor in electrical communication with the near field telemetry module and the far field telemetry module. The processor is configured to establish, in relation to a communication signal received by the near field telemetry module, a time period during which communication via the far field telemetry module is available, and operate the IMD according to the received second information upon receiving third information via the near field telemetry link.

摘要:
A telemetry system enabling radio frequency (RF) communications between an implantable medical device and an external device, or programmer, in which the RF circuitry is normally maintained in a powered down state in order to conserve power. At synchronized wakeup intervals, one of the devices designated as a master device powers up its RF transmitter to request a communications session, and the other device designated as a slave device powers up its RF transmitter to listen for the request. Telemetry is conducted using a far field or near field communication link.
摘要:
An implantable medical device comprising a far field RF transmitter and receiver, a controller circuit communicatively coupled to the RF transmitter and receiver, and a wakeup timer circuit integral to, or communicatively coupled to, the controller. The controller is configured to initiate power up of the RF transmitter and receiver during a wakeup interval defined by the wakeup timer circuit, detect a digital key received from a second device during the wakeup interval, transmit a response using the RF transmitter when the digital key is received, and receive a communication from the second device and resynchronize the wake-up timer according to a time of the communication.

摘要:
This document discusses a system that includes an intermediary telemetry interface device for communicating between a cardiac rhythm management system or other implantable medical device and a programmer or other remote device. One example provides an inductive near-field communication link between the telemetry interface and the implantable medical device, and a radio-frequency (RF) far-field communication link between the telemetry interface device and the remote device. The telemetry interface device provides data buffering. In another example, the telemetry interface device includes a data processing module for compressing and/or decompressing data, or for extracting information from data. Such information extraction may include obtaining heart rate, interval, and/or depolarization morphology information from an electrogram signal received from the implantable medical device.
