  • Patent number: 11219754
    Abstract: Apparatus includes a flexible intraventricular receptacle that assumes a first volume upon passage of fluid that is not blood into the receptacle and a second, smaller volume upon passage of the fluid out of the receptacle. An expandable extracardiac receptacle expands upon transfer of the fluid into the extracardiac receptacle from the intraventricular receptacle and contracts upon passage of the fluid out of the extracardiac receptacle. A transmyocardial conduit allows passage of the fluid between the intraventricular receptacle and the extracardiac receptacle responsively to a cardiac cycle. During ventricular systole, a volume of fluid is expelled from the intraventricular receptacle, through the conduit, and into the extracardiac receptacle, producing a corresponding decrease in a total volume of the ventricle during isovolumetric contraction of the ventricle. Other embodiments are also described.

  • Patent number: 11185269
    Abstract: Optimizing psychiatric and physiologic monitoring of a patient having PTSD or anxiety-related mental health condition. According to an embodiment, one or more physiological variables are longitudinally measured; resting heart rate is measured from which a timeseries is constructed; outlier anomalous values are removed from the timeseries, it is de-trended and/or de-meaned; and a serial normal sinus rhythm beats (SDNN) and/or other parameters are determined. Fractal properties of the serial SDNN values are calculated, such as the Hurst exponent alpha via detrended fluctuation analysis (DFA) or spectral regression; and other measures of chaos and nonlinearity are calculated, such as the Shannon entropy of the SDNN or related timeseries. Where such measures indicate a statistically-significant transgression of a context-indexed reference range, a notification is provided to a case management clinician or caregiver so that appropriate additional evaluation and diagnosis and treatment may be undertaken.

  • Patent number: 11147499
    Abstract: A method of determining atrial fibrillation includes determining if a patient's pulse beats form an irregular pattern. If so, presence of an irregular pulse is indicated to a patient and, an electrocardiogram is obtained for determining atrial fibrillation. Initially, a pulse is detected at regular time intervals from a first appendage when motionless, using a pulse detector and pulse rhythms from a succession of time intervals, each corresponding to a respective interval of time between successive pulse beats of a sequence of the pulse beats. Then, a second appendage makes contact with an electrically conductive unit, and electrocardiogram signals are detected simultaneously with pulse rhythms while the first appendage is motionless and both appendages are relaxed. The signals are then analyzed to determine whether, in combination, they are indicative of atrial fibrillation.
