  • Patent number: 10478612
    Abstract: Various systems and methods for non-invasively monitoring and treating a medical condition of interest via transcutaneous stimulation of a target nerve are described. For instance, a subject can be monitored for improvement of a medical condition, where such improvement corresponds with a decrease in the threshold level at which a sensory or motor response is elicited in a subject upon stimulation as compared to a baseline level. Further, transcutaneous stimulation of the nerve can also treat the condition. Both monitoring and treatment can be carried out in a non-invasive manner substantially free of a painful response via electrical nerve stimulation of a target nerve, where the stimulation is delivered from an electrode placed on a non-glabrous skin surface. The electrode placement sufficiently immobilizes the target nerve such that the stimulation is effective and can be delivered in a controlled manner.

  • Patent number: 10362951
    Abstract: The present disclosure uses physiological data, ECG signals as an example, to evaluate cardiac structure and function in mammals. Two approaches are presented, e.g., a model-based analysis and a space-time analysis. The first method uses a modified Matching Pursuit (MMP) algorithm to find a noiseless model of the ECG data that is sparse and does not assume periodicity of the signal. After the model is derived, various metrics and subspaces are extracted to image and characterize cardiovascular tissues using complex-sub-harmonic-frequencies (CSF) quasi-periodic and other mathematical methods. In the second method, space-time domain is divided into a number of regions, the density of the ECG signal is computed in each region and inputted into a learning algorithm to image and characterize the tissues.

  • Patent number: 10299693
    Abstract: Techniques for using multiple physiological parameters to provide an early warning for worsening heart failure are described. A medical device monitors a primary diagnostic parameter that is indicative of worsening heart failure, such as intrathoracic impedance or pressure, and one or more secondary diagnostic parameters. The medical device detects worsening heart failure in the patient based on the primary diagnostic parameter when an index that is changed over time based on the primary diagnostic parameter value is outside a range of values, termed the threshold zone. When the index is within the threshold zone, the medical device detects worsening heart failure in the patient based on the one or more secondary diagnostic parameters. Upon detecting worsening heart failure, the medical device may, for example, provide an alert that enables the patient to seek medical attention before experiencing a heart failure event.

  • Patent number: 10226631
    Abstract: Systems, devices, and methods for determining occurrences of myocardial infarctions are disclosed. In one embodiment, a method of sensing for an occurrence of a myocardial infarction may include sensing a baseline accelerometer signal during a baseline, determining a baseline template based on one or more characteristics of the baseline accelerometer signal, and storing the baseline template in a memory. The method may further include sensing an accelerometer signal during a test period subsequent to the baseline, determining a test template based on one or more characteristics of the accelerometer signal during the test period, and comparing the baseline template with the test template, and based on the comparison, determining if a myocardial infarction occurred in the patient's heart. If it is determined that a myocardial infarction occurred in the patient's heart, the method may further include displaying an indication on a display that a myocardial infarction occurred.

  • Patent number: 10201286
    Abstract: An algorithm for determining heart rate by removing motion artifacts from a PPG signal in the frequency domain utilizes a principal component analysis. Some examples of the present disclosure process PPG signals in combination with accelerometer signals to remove unwanted artifacts in the frequency domain. For example, principal components of the accelerometer signal can be generated and combined with the PPG signal to filter out acceleration contributions represented in the PPG signal to reveal heart rate peaks. Additionally, in some examples, templates may be stored for correlation with candidate heart rate peaks to select those peaks with the highest correlations with the stored templates.

  • Patent number: 10188314
    Abstract: A method of detecting a localization element/sheath state change with a localization system includes establishing a localization field using a plurality of localization field generators, obtaining first and second localization signals from first and second catheter-borne localization elements within the localization field, respectively, comparing the quadrature components of the first and second localization signals, and detecting a localization element/sheath state change for one of the catheter-borne localization elements based on the comparison between quadrature components. For example, withdrawal of a localization element into an introducer sheath can be detected when the comparison between quadrature components exceeds a preset amount. Conversely, re-emergence of the localization element from the introducer sheath can be detected when the comparison between quadrature components returns below the preset amount.

  • Patent number: 10182767
    Abstract: Systems and methods are described for subject rehospitalization management. In an example, multiple physiologic signals can be obtained from a subject using multiple sensors. In response to a hospitalization event, pre-hospitalization characteristics of the multiple physiologic signals can be identified. Post-hospitalization characteristics of the multiple physiologic signals can be identified, including characteristics that differ from their corresponding pre-hospitalization characteristics. Later subsequent physiologic signals can be further monitored after the hospitalization event, such as using the same multiple sensors, and subsequent physiologic signal characteristics can be identified. In an example, a heart failure diagnostic indication can be determined using information about the pre-hospitalization characteristics, the post-hospitalization characteristics, and the subsequent characteristics.

  • Patent number: 10143393
    Abstract: Some embodiments described herein relate to a method that includes defining an electro-anatomical model of a heart. The electro-anatomical model can include conduction patterns for multiple patterns or phases identified by a measurement instrument. The electro-anatomical model can also include a voltage map of the heart. A portion of the heart containing a rotor can be identified based on circulation in one phase of the model. The rotor can be determined to be stable based on that portion of the heart having circulation in another phase of the model. The rotor can be characterized as a substrate rotor based on the rotor being stable and based on the voltage or a change in voltage at the portion of the heart containing the rotor. The rotor can be treated or ablated when the rotor is determined to be a substrate rotor.

  • Patent number: 10141687
    Abstract: A connector comprises a housing, a slider, a regulating portion and an operation portion. The housing has a lock portion. The slider has a release portion and a regulated portion. Under a mated state where the connector is mated with a mating connector having a mating lock portion, the lock portion locks the mating lock portion of the mating connector, and the regulating portion faces the regulated portion and regulates a rearward movement of the slider. When the operation portion is operated to be pressed inward of the connector, at least one of the regulating portion and the regulated portion is moved, and the regulating portion does not regulate the rearward movement of the slider. When the slider is moved rearward, the release portion moves the lock portion and releases the mating lock portion.
