In an embodiment, once a communication session is established between the BS and the MD, the BS selectively turns a drop link mode on and off. The drop link mode is a communication mode that while turned on (i.e., enabled) reduces and preferably minimizes the length of time that an RF link is maintained between the BS and the MD. In accordance with an embodiment, at any given time during a communication session the drop link mode is either turned on (i.e., enabled) or turned off (i.e., disabled).

During telemetry, particularly outside of a recharge period, the reactance may be set so that the tank circuit is tuned to the telemetry frequency. During recharge, the reactance is set so that the tank circuit is tuned to the recharge frequency. Furthermore, the tank circuit may have a Q that is sufficiently small that the tank circuit receives telemetry frequency signals that can be decoded by a receiver while the tank is tuned to the recharge frequency so that telemetry for recharge status purposes may be done during the recharge period without changing the tuning of the tank circuit.

  • Patent number: 9610450
    Abstract: An antenna structure, for use in an implantable medical device, may include an inner portion that is magnetically coupled to an outer portion. In one example, the inner and outer portions include conductive loops. In accordance with the techniques of this disclosure, a capacitive sensor is electrically coupled to one of the conductive loops of the antenna of the implantable medical device. As the capacitance of the capacitive sensor changes as a function of the sensed parameter, an impedance of the antenna varies with the output of the capacitive sensor. This variation in impedance of the antenna modulates a carrier signal with the measured parameter. In other words, the measured parameter is modulated onto the carrier signal as a change in amplitude caused by variation in impedance of antenna during radiation/transmission.

  • Patent number: 9585582
    Abstract: A system for determining the Q and J points of an electrocardiogram (ECG) combines a WLT-based Q, J detection algorithm with signal quality assessment for lead selection. A Q, J detector (24) receives a beat-cycle waveform for the beat under consideration from each of a plurality (N) of ECG leads, and assesses signal quality for each lead using signal quality assessor (SQA) components 261, 262 . . . 26N. The leads with “good” signal qualities are employed for a multichannel waveform length transform (WLT), which yields a combined waveform length signal (CWLS). The Q and J points are then determined from the CWLS.

  • Patent number: 9533162
    Abstract: Systems and methods are disclosed in which an external device such as a consumer mobile device (e.g., smart phone) is used as an external controller to bi-directionally communicate with an Implantable Medical Device (IMD) using a dedicated patient remote control (RC) as an intermediary device to translate communications between the two. The dedicated RC contains a graphical user interface allowing for control and monitoring of the IMD even if the mobile device is not present in the system, which is useful as a back-up should the mobile device experience problems. Use of the dedicated RC as an intermediary device broadens the utility of other computing devices to operate as an external controller for an IMD even if the computing device and IMD do not have compliant communication means.

  • Patent number: 9468773
    Abstract: A tethering feature includes an elongate break-away member and a base, and forms a proximal end of an implantable medical device housing. A tether attachment zone of the break-away member extends between break-away member ends, and the base includes a pair of supports, wherein each end of the break-away member is wrapped around a corresponding support. A delivery catheter tether may be attached to the device tethering feature by passing a looped portion of the tether around the tether attachment zone. The device may be untethered from the catheter by applying a pull force through the attached tether, while a distal end of a shaft of the catheter, which abuts the device proximal end, provides a back-up force, the pull force unwrapping each end of break-away member from the corresponding base support.

  • Patent number: 9403021
    Abstract: A driving circuit useful in a magnetic inductive coupling wireless communication system is disclosed. The circuit includes an inductor (coil) and capacitor in series selectively coupled to a power source such as a rechargeable battery. The LC circuit is made to resonate in accordance with a Frequency Shift Keying or other protocol. Such resonance produces a voltage across the inductor. This voltage is used to create a first voltage either by tapping into the coil, or by providing a transformer. The first voltage is coupled to the rechargeable battery by a diode. When the circuit resonates, and when the first voltage exceeds the voltage of the power source, the diode turns on, thus shunting excess current back to recharge the rechargeable battery. By use of this circuit, energy is conserved. Additionally, oscillations can be quickly dampened so as to allow the circuit to transmit at high data rates.

    Abstract: This disclosure describes an operational mode of a telemetry module. A device, such as a programming device, operating in accordance with the techniques of this disclosure determines that a transceiver of an implantable medical device is operating in a duty cycled operational mode that includes at least one interval during which the transceiver is powered down interleaved with intervals during which the transceiver is powered up, e.g., for transmitting or receiving communications over an established communication session. The programming device is configured to transmit information during the at least one interval in which the transceiver of the implantable medical device is powered down. Doing so ensures that the channel over which the programmer and implantable medical device communicate will not be usurped by another device.
