  • Patent number: 11116988
    Abstract: Implantable medical devices such as leadless cardiac pacemakers may include a rechargeable power source. In some cases, a system may include an implanted device including a receiving antenna and an external transmitter that transmits radiofrequency energy that may be captured by the receiving antenna and then be converted into electrical energy that may be used to recharge a rechargeable power source. Accordingly, since the rechargeable power source does not have to maintain sufficient energy stores for the expected life of the implanted device, the power source itself and thus the implanted device, may be made smaller while still meeting device longevity expectations.

  • Patent number: 11101036
    Abstract: Devices, systems, and methods are disclosed for relaying information from a cardiac pacemaker to an external device. Logic on the pacemaker modulates a heartbeat clock of the pacemaker to encode information onto a blood pressure sequence by adding or subtracting a small subinterval to or from a pulse repetition interval of the pacemaker. A muscle stimulator beats the heart according to the modulated sequence. A monitoring device external to the body monitors the blood pressure to retrieve the encoded information, or message. The encoded information is then decoded to determine the information in the message. This information may concern the pacemaker as well as other devices within the body that communicate with the pacemaker such as blood monitors, etc. Since the message is conveyed via simple modulation of the heart beat intervals, no separate transmitter is required in the pacemaker which would otherwise increase cost and decrease battery life.

  • Patent number: 10874864
    Abstract: The disclosed techniques allow for externalizing errors from an implantable medical device using the device's charging coil, for receipt at an external charger or other external device. Transmission of errors in this manner is particularly useful when telemetry of error codes through a traditional telemetry coil in the implant is not possible, for example, because the error experienced is so fundamental as to preclude use of such traditional means. By externalizing the error via the charging coil, and though the use of robust error modulation circuitry in the implant designed to be generally insensitive to fundamental errors, the external charger can be consulted to understand the failure mode involved, and to take appropriate action.

    Abstract: Physiological sensors may be utilized to obtain physiological data for a user. The sensor data may be utilized in predicting a user's outcome to a medical intervention using one or more models. The models may be automatically executed in response to receiving certain types and/or amount of data, such as data received from one or more physiological remote sensors, such as Internet of Things sensors. The sensors may include heart rate sensors, arterial pressure sensors, glucose sensors, temperature sensors, weight sensors, blood oxygen sensors, urine sensors, saliva sensors, skin conduction sensors, muscle sensors, brain signal sensors, and/or other sensors. A sensor may communicate over the 2360-2400 MHz and/or the 30-37.5 MHz radio frequency (RF) band. The data may be received from a networked data store. Execution of the models may identify health issues in substantially real time, and the operation of one or more medical devices may be modified and/or a communication may be generated.

  • Patent number: 10792493
    Abstract: The present invention relates, generally, to scientific and medical system methods for diagnosis of implantable cardioverter defibrillator (ICD) lead conductor anomalies, in particular conductor migration and externalization within an ICD implantable cardiac lead. The method uses an “imaginary” component of the high frequency transmission line impedance having certain spectral changes that correspond to movements of the conductor or an “imaginary impedance”. This allows the detection of conductor migration and small insulation failures.

  • Patent number: 10796505
    Abstract: A diagnostic system includes a microcontroller having a first A/D converter, first and second applications, and a first analog multiplexer electrically between a first voltage regulator and the first A/D converter. The first application sets a first overvoltage diagnostic flag to a first fault value if a first voltage of the first voltage regulator that is measured by the first A/D converter is greater than a first voltage, and in response further transitions a contactor to an open operational state. The second application sets a second overvoltage diagnostic flag to a second fault value if a second voltage of the first voltage regulator that is measured by the first A/D converter is greater than a second voltage, and in response further transitions the contactor to the open operational state.

  • Patent number: 10788554
    Abstract: A method for setting an operating parameter of a medical device is provided. The method includes determining a current operating mode of the medical device. A time span available for setting the operating parameter is derived from the determined current operating mode. A setting range of the operating parameter necessary for fulfilling a pre-determined criterion is determined. A setting time necessary for setting the operating parameter according to the determined setting range is determined, and the operating parameter is set according to the setting range, provided the time span available for the setting is at least as long as the necessary setting time.

  • Patent number: 10786279
    Abstract: Subcutaneous implantation tools and methods of implanting a subcutaneous device using the same. The tool may include a tool body having a longitudinally extending recess having a distal opening and having a tunneler at a distal end of the tool body extending from the distal opening of the recess. The tool may include a plunger slidably fitting within at least a portion of the tool body recess. The recess may be configured to receive an implantable device and the tunneler preferably extends distally from the recess at a position laterally displaced from the device when the device is so located in the recess. Movement of the plunger distally within the recess advances the device distally out of the recess and alongside of and exterior to the tunneler.
