  • Publication number: 20210030295
    Abstract: Systems and methods for calibrating an orientation of an implantable device in a patient is described. An exemplary system includes a calibration circuit that can receive acceleration information sensed from an implantable medical device (IMD) implanted in a patient, and receive reference acceleration information sensed from a reference device associated with the patient. The acceleration information and the reference acceleration information are acquired when the patient assumes a first posture or in a first position. The calibration circuit determines a spatial relationship between an orientation of the IMD and a reference orientation of the reference device using the received acceleration information and the received reference acceleration information, and calibrate subsequent acceleration information sensed from the IMD using the determined spatial relationship to correct for the orientation of the IMD.

  • Publication number: 20200364327
    Abstract: Embodiments herein relate to sensor based authentication between an implantable medical device (IMD) and an external device. In an embodiment, the IMD includes a wireless communication module and an internal inertial measurement unit (IMU) capable of measuring vibrations, movement, or rotation. The IMD is configured to record an internal IMU signal from the internal IMU. The external device includes a wireless communication module and an external IMU. The external device is configured to record an external IMU signal from the external IMU. The system further includes a data processing system to receive a first level communication that can include the internal IMU signal, the external IMU signal, or both, compare data from the internal IMU signal with data from the external IMU signal, and authorize a second level communication based on results of the comparison step.

  • Publication number: 20200289057
    Abstract: Systems and methods for monitoring and evaluating the function of a prosthetic heart valve (PHV) implanted in a patient are discussed. An exemplary medical-device system can receive heart sounds information including vibrational or acoustic information generated by an implanted PHV, and generate an indicator of function of the PHV using a HS metric of received acceleration information. An alert of PHV dysfunction can be presented to a system user. The PHV function may be monitored during a valve replacement procedure to assist in position adjustment of the prosthetic value, or after the valve replacement procedure to assess patient progress in recovery. According to some embodiments, the system can generate a risk indicator indicating patient natural valve function and a need for heart valve repair or replacement.

  • Publication number: 20200288997
    Abstract: Systems and methods for detecting cardiac arrhythmia are discussed. An exemplary medical-device system includes an arrhythmia detector circuit that receives physiologic information, including respiration and heart beat information a patient, and determines whether a respiratory sinus arrhythmia (RSA) is present or absent using the respiration and the heart beat information. An indication of the presence or absence of RSA may be stored in a memory. The arrhythmia detector circuit can detect an AT episode using the indication of RSA.

  • Publication number: 20200129099
    Abstract: Systems, devices, and methods for monitoring and assessing blood glucose level in a patient are discussed. An exemplary system receives physiologic information from a patient using an ambulatory medical device. The physiologic information is correlated to, and different from, a direct glucose level measurement. The system determines a glucose index indicative of an abnormal blood glucose level using the received physiologic information by the two or more physiologic sensors. The system may use the glucose index to initiate or adjust a therapy, or to trigger a glucose sensor, separate from the two or more physiologic sensors, to directly measure blood glucose concentration.

  • Publication number: 20200077913
    Abstract: Systems and methods for reconstructing heart sounds from heart sound samples taken under a sub-optimal condition, such as at a low sampling rate, are discussed. An exemplary system receives acceleration information from a patient sensed at a first sampling rate, and generate a heart sound ensemble of portions of acceleration information over multiple cardiac cycles. The system can reconstruct a heart sound segment to have a second sampling rate, higher than the first sampling rate, using the generated heart sound ensemble. A heart sound metric can be generated using the reconstructed heart sound segment, and used for detecting a cardiac event, such as a cardiac arrhythmia episode, or a worsening heart failure event.

  • Publication number: 20190343480
    Abstract: Systems and methods for detecting heart sound information from a subject's head are described. A system embodiment includes a headgear to be worn on the subject's head, and first and second sensors to sense respectively first and second physiologic signals each representing vibration, motion, or displacement conducted through patient body tissue. The sensed physiologic signals contain heart sound information. At least one of the first or the second sensor is included in the headgear, and placed at a head location to sense a physiologic signal indicative of heart sounds. The system includes a processor to generate a composite signal using the sensed first and second physiologic signals. The system may generate a heart sound metric using the composite signal, and detect a cardiac event such as an arrhythmia or worsening heart failure.

  • Publication number: 20190223782
    Abstract: Systems and methods for sensing respiration from a subject are discussed. An embodiment of a respiration monitoring system may include a respiration analyzer circuit to select a physiologic signal from a plurality of signals of different types indicative of respiration, such as between first and second physiologic signals that are respectively detected using first and second detection algorithms, and to compute one or more respiration parameters using the selected signal. The system may select or adjust a respiration detection algorithm for detecting the respiration parameters. The physiologic signal, or the respiration detection algorithm, may each be selected based on a signal characteristic or a patient condition. A cardiopulmonary event may be detected using the computed respiration parameter.

  • Publication number: 20190201702
    Abstract: A system and method for communication between an IMD and an external reader includes bringing a portion of a patient's body into contact with a device-body contact surface of an external reader. The reader transmits a first transdermal carrier wave from the contact surface into the patient's body, where the first carrier wave includes a request for communication with the IMD. The transdermal carrier waves are electrical conductive waves, optical waves, or acoustic waves. Upon detection of the first carrier wave, the IMD transmits a second transdermal carrier wave including a request for an access key from the reader and the reader replies by transmitting a third transdermal carrier wave including the access key back to the IMD. If the access key is valid, the IMD transmits information by radio frequency (RF) in an RF communication mode or a fourth transdermal carrier wave including data from the IMD.
