Systems, apparatus, methods and computer-readable storage media facilitating management of operation of an implantable medical device (“IMD”) using a number of communication modes are provided. An IMD is configured to operate in a disabled mode wherein radio frequency (RF) telemetry communication is disabled, or operate in a first advertising mode using the RF telemetry communication. The IMD receives a clinician session request from a clinician device via an induction telemetry protocol while operating in the disabled mode or the first advertising mode, and transitions to operating from the disabled mode or the first advertising mode to operating in a second advertising mode based on receiving the clinician session request. From the second advertising mode, the IMD can establish a clinician telemetry session with the clinician device using the RF telemetry communication and a unique security mechanism facilitated by an identifier for the clinician device included in the clinician session request.

An external data retrieval apparatus includes a transceiver, and a processing system coupled to the transceiver. The processing system obtains a plurality of measures over a period of time. The measures relate to a quality of a communications channel between the data retrieval apparatus and an active implantable medical device. The processing system determines a trend in the plurality of measures over the period of time, and then determines a preferred time during which to retrieve data based on the trend.

An RF telemetry receiver circuit for active implantable medical devices. The baseband binary signal (D.sub.b) is doubly modulated by a low frequency carrier (F.sub.m) and by a high frequency carrier (F.sub.c). The receiver circuit is a semi-passive non heterodyne circuit, devoid of a local oscillator and mixer. It comprises an antenna (104), a passive bandpass filter (108) centered on the high-frequency carrier (F.sub.c), a passive envelope detector (120-126) and a digital demodulator (116). The envelope detector comprises a first diode circuit (120) of non-coherent detection, an active bandpass filter (122) centered on a frequency (2.F.sub.m) twice the low frequency carrier and having a bandwidth (2.D.sub.b) twice the baseband bandwidth, and a second diode circuit (124) of non-coherent detection, outputting a baseband signal applied to the digital demodulation stage (116).

Far field telemetry operations are conducted between an external device and an implantable medical device while power is being transferred to the implantable medical device for purposes of recharging a battery of the implantable medical device. The far field operations may include exchanging recharge information that has been collected by the implantable medical device which allows the external device to exercise control over the recharge process. The far field operations may include suspending far field telemetry communications for periods of time while power continues to be transferred where suspending far field telemetry communications may include powering down far field telemetry communication circuits of the implantable medical device for periods of time which may conserve energy. The far field operations may further include transferring programming instructions to the implantable medical device.

Systems, apparatus, methods and computer-readable storage media facilitating telemetry overuse reduction in an implantable medical device (“IMD”) are provided. In one embodiment, an IMD includes a housing configured to be implanted at least partially within a patient, a memory and circuitry within the housing and a processor that executes executable components stored in the memory. The executable components include: a communication component configured to establish a telemetry connection with an external device to communicate data associated with sensed physiological data or therapy; and an authorization component configured to determine whether the external device is authorized to communicate with the IMD, wherein the communication component is further configured to disable the telemetry connection with the external device and prevent additional communication with the external device for a defined period of time based on a determination that the external device fails to be authorized to communicate with the IMD.

An implantable medical device (IMD) with a receiver having a higher power mode and a lower power mode. In the higher power mode, the receiver can receive a communication from an external device and pass the received communication to a controller, and in the lower power mode the receiver may not receive the communication from the external device and pass the received communication to the controller. In some cases, the IMD may include a physiological sensor providing an output to the controller, and the controller may control whether the receiver is in the higher power mode or the lower power mode based at least in part on the output of the physiological sensor.

System and methods for energy adaptive communications between medical devices are disclosed. In one example, a medical device includes a communication module configured to deliver a plurality of pulses to tissue of a patient, where each pulse has an amount of energy. A control module operatively coupled to the communication module, may be configured to, for each delivered pulse, determine whether the delivered pulse produces an unwanted stimulation of the patient and to change the amount of energy of the plurality of pulses over time so as to identify an amount of energy that corresponds to an unwanted stimulation threshold for the pulses. The control module may then set a maximum energy value for communication pulses that is below the unwanted stimulation threshold, and may deliver communication pulses below the maximum energy value during communication with another medical device.

Aspects of the subject matter described in this disclosure can be implemented in an implant device capable of being configured by an external hospital interrogator device when the external hospital interrogator device is authenticated, and capable of communicating data regarding a patient when paired with an external home interrogator device. The implant device includes RF communications circuitry, one or more sensors configured to measure and/or collect data regarding the patient, and a control system. The control system is configured to receive instructions from the external hospital interrogator device for configuring the implant device when the external hospital interrogator device is authenticated, and receive identification data from the external hospital interrogator device for pairing the implant device with the external home interrogator device.
