  • Patent number: 12161487
    Abstract: Techniques are disclosed for monitoring a patient for the occurrence of cardiac arrhythmias. A computing system obtains a cardiac electrogram (EGM) strip for a current patient. Additionally, the computing system may apply a first cardiac rhythm classifier (CRC) with a segment of the cardiac EGM strip as input. The first CRC is trained on training cardiac EGM strips from a first population. The first CRC generates first data regarding an aspect of a cardiac rhythm of the current patient. The computing system may also apply a second CRC with the segment of the cardiac EGM strip as input. The second CRC is trained on training cardiac EGM strips from a smaller, second population. The second CRC generates second data regarding the aspect of the cardiac rhythm of the current patient. The computing system may generate output data based on the first and/or second data.

  • Patent number: 12161464
    Abstract: Methods, systems, and devices for improving continuous glucose monitoring (“CGM”) are described herein. More particularly, the methods, systems, and devices describe applying micro machine learning models to generate predicted sensor glucose values. The system may use the predicted sensor glucose values to display a sensor glucose value to a user. The layered models may generate more reliable sensor glucose predictions across many scenarios, leading to a reduction of sensor glucose signal blanking. The methods, systems, and devices described herein further comprise applying a plurality of micro model to estimate sensor glucose values under outlier conditions. The system may prioritize the models that are trained for certain outlier conditions when the system detects those outlier condition based on the sensor data.

  • Patent number: 12161401
    Abstract: The present disclosure relates to devices, systems and methods providing evaluation and feedback to an operator of a device providing neuromodulation treatment, such as modulation of renal nerves of a human patient. In one embodiment, for example, a system monitors parameters or values generated before treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of various electrical properties associated with an electrode carried by a catheter. The electrode measures an electrical property of biological material making contact with the electrode while deploying the electrode, the electrical property being dependent on a ratio of a wall-interface area to a fluid-interface area.

  • Patent number: 12161406
    Abstract: Devices and systems used to ablate tissue of a tumor using laser energy are disclosed. The devices and systems include a laser probe and a magnetic resonance (MR) safe temperature probe. The MR safe temperature probe includes an optical sensor. A bone anchor fixture separates the laser probe and the MR safe temperature probe to prevent interference in the MR safe temperature probe data. Proton Resonance Frequency (PRF) thermometry is used to model a temperature of a pixel of an MR image located adjacent the optical sensor. The modeled pixel temperature and the measured temperature are compared and monitored. Exceeding a threshold difference value causes an intervening action to occur.

    Abstract: A method of operating an implantable blood pump and a pacing device, the method includes determining an end diastolic volume (EDV) and ejection fraction of one from the group consisting of the right ventricle and the left ventricle at a predetermined pump set speed. An average flow rate based on the predetermined pump set speed is determined. A target heart rate based at least in part on the determined EDV, ejection fraction, and average flow rate is determined. A lower rate for the pacing device is determined, the pacing device being in electrical communication with a chamber of the heart. The chamber of the heart is paced when a measured heart rate drops below the lower rate.

  • Patent number: 12156745
    Abstract: A method of detecting hypertension in a patient having an implantable blood pump, the method includes operating the implantable blood pump at a first pump set speed during a first period of time. A first flow rate minimum during a cardiac cycle of the patient is measured during the first period of time. The first pump set speed is reduced by at least 200 rpm during a second period of time after the first period of time to a second pump set speed, the second period of time being less than the first period of time. A second flow rate minimum is measured during a cardiac cycle during the second period of time. If the second flow rate minimum decreases during the second period of time at the second pump set speed by more than a predetermined amount, an alert is generated indicating a presence of hypertension.
