  • Patent number: 9048881
    Abstract: The present invention provides a method of time-synchronized data transmission in induction type power supply system, comprising timers and programs installed in a supplying-end module and a receiving-end module to predict the time for generating the trigger signal at the receiving-end end and perform steps for detecting signals to avoid omission. Under the condition of high power transmission, power output on the supplying-end coil is pre-reduced prior to the time expected for receiving trigger data, making the main carrier wave amplitude decrease in a short time period. In every process of data transmission, timers are mutually calibrated and synchronized again to transmit power without detecting and receiving in the period when no data are expected to be transmitted, thus preventing interference of power load noise and enabling the induction type power supply system to transmit data code stably.

  • Patent number: 8995949
    Abstract: Devices and systems provide for proximity based selection of an implantable medical device for far field communication with an external device. By using a proximity communication that is limited to the IMD of interest during the selection process, the external device can eliminate those IMDs that are in range of far field communications but are able to receive the proximity communication. Thus, information may be shared via a proximity communication that is validated via a far field communication, or shared via a far field communication as a challenge and then validated via a proximity communication. The proximity communication may be used to initially limit the number of devices that respond to a discovery request and then subsequently used to select the intended implantable medical device as well as automatically select the appropriate therapy application corresponding to the selected IMD.

  • Patent number: 8983606
    Abstract: An implantable medical device (IMD) adjusts a sensing configuration of a sensing module prior to or immediately subsequent to entering an environment having an external source that generates the interfering signal. The IMD may, for example, adjust a sampling frequency, resolution, input range, gain, bandwidth, filtering parameters, or a combination of these or other sensing parameters of the sensing module. These adjustments enable the sensing module to obtain a more detailed representation of the sensed signals, including the noise components of the sensed signals caused by the interfering signal. Without having an adequate representation of the noise components of the sensed signal, it is difficult to separate the noise components of the sensed signal from the cardiac electrical signal.

  • Patent number: 8825173
    Abstract: For supplying energy to a medical implant (100) in a patient's body a receiver (102) cooperates with an external energizer (104) so that energy is wirelessly transferred. A feedback communication system (109) sends feedback information from the receiver to the energizer, the feedback information being related to the transfer of energy to the receiver. The feedback communication system communicates using the patient's body as an electrical signal line. In particular, the communication path between the receiver and the external energizer can be established using a capacitive coupling, i.e. the feedback information can be capacitively transferred over a capacitor having parts outside and inside the patient's body. An energy balance between the amount of energy received in the receiver and the energy used by the medical implant can be followed over time, and then the feedback information is related to the energy balance.

  • Patent number: 8649757
    Abstract: Devices and systems provide for proximity based selection of an implantable medical device for far field communication with an external device. By using a proximity communication that is limited to the IMD of interest during the selection process, the external device can eliminate those IMDs that are in range of far field communications but are able to receive the proximity communication. Thus, information may be shared via a proximity communication that is validated via a far field communication, or shared via a far field communication as a challenge and then validated via a proximity communication. The proximity communication may be used to initially limit the number of devices that respond to a discovery request and then subsequently used to select the intended implantable medical device as well as automatically select the appropriate therapy application corresponding to the selected IMD.

  • Patent number: 8626277
    Abstract: A computer-implemented electrocardiographic data processor with time stamp correlation is provided. A monitoring circuit includes a persistent memory and power supply that powers an encoder that determines a differential voltage between a current discrete digital voltage value and a prior voltage value. The differential voltage is stored into the persistent memory in a digitized data stream representative of analog cardiac action potential signals. Digitally-encoded voltage values and time stamps are retrieved from the persistent memory. A post-processing application executes. A set of output voltages and voltage differences that each correspond to lower and upper bounds of voltage is stored. Each retrieved voltage value is compared to the voltage bounds and the voltage differences within which each retrieved voltage value falls is identified. The output voltages corresponding to the voltage differences is selected.

  • Patent number: 8594798
    Abstract: Apparatuses and methods support multi-modal operation of a medical device system for a nervous system disorder. The medical device system comprises an implanted component and an external component and supports a first feature and a second feature that are associated with the treatment therapy. The medical device system supports both features when the implanted component and the external component are coupled. If the external component is decoupled, the implanted component continues to support the first feature. Moreover, the embodiment may support a plurality of features during a treatment interval. Another aspect of the invention allows for modularly expanding a medical device system in order to add a feature that enhances existing functionality or that provides additional functionality. In an embodiment, a module that is associated with an external component of the medical device system supports the added feature.

  • Patent number: 8571678
    Abstract: External instruments and implantable medical devices communicate using modulation parameter settings that may be adapted during communication sessions based on a quality of the wireless communications link. An analysis of the quality of the link is performed and a request to change modulation parameters is sent to one of the devices by the other. The analysis may be based on measuring noise and interference during idle communication frames. The devices may then change the modulation parameter settings, for the uplink, downlink, or both. The devices may also employ a recovery operation to revert back to the previous modulation parameter settings if the transmissions are not properly received using the changed modulation parameter settings. The modulation parameter settings may include modulation type, modulation symbol rate, and the like.

  • Patent number: 8565874
    Abstract: An implantable medical device (IMD) includes a lead having one or more sensing electrodes and one or more therapy delivery electrodes, and a sensor configured to detect the presence of static and time-varying scan fields in a magnetic resonance imaging (MRI) environment. A controller, in electrical communication with the lead and the sensor, is configured to process signals related to tachycardia events sensed via the one or more sensing electrodes and to deliver pacing and shock therapy signals via the one or more therapy delivery electrodes. The controller compares the sensed static and time-varying scan fields to static and time-varying scan field thresholds. The controller controls delivery of anti-tachycardia pacing and shock therapy signals as a function of the detected tachycardia events, the comparison of the sensed static scan field to the static scan field threshold, and the comparison of the time-varying scan fields to the time-varying scan field thresholds.
