Patent number: 11883174Abstract: Foley type catheter embodiments for sensing physiologic data from a urinary tract of a patient are disclosed. The system includes the catheter and a data processing apparatus and methods for sensing physiologic data from the urinary tract. Embodiments may also include a pressure sensor having a pressure interface at a distal end of the catheter, a pressure transducer at a proximal end, and a fluid column disposed between the pressure interface and transducer. When the distal end is residing in the bladder, the pressure transducer can transduce pressure impinging on it into a chronological pressure profile, which can be processed by the data processing apparatus into one or more distinct physiologic pressure profiles, for example, peritoneal pressure, respiratory rate, and cardiac rate. At a sufficiently high data-sampling rate, these physiologic data may further include relative pulmonary tidal volume, cardiac output, relative cardiac output, and absolute cardiac stroke volume.Type: GrantFiled: March 1, 2021Date of Patent: January 30, 2024Assignee: Potrero Medical, Inc.Inventors: Daniel R.

Patent number: 11883176Abstract: A wearable self-contained Smart ECG Sensor Patch (SEP) is provided for acquiring, analyzing and transmitting ECG data, heart rate and heart rate variability (heart rate variability) parameters to a host device via a secure Bluetooth low energy link. SEP incorporates all circuitry for acquisition, analysis and communication, and a battery on a small flexible substrate with two gold electrodes on the reverse side. Prior to on-board analysis, noise and motion artifacts are detected and ignored. SEP has been validated with archived ECG signals and testing on human subjects. The continuous acquisition and unique on-board analytics permit SEP to be used for prolonged monitoring scenarios with automatic alarm generations. SEP's aggressive power management techniques enable it to operate on a single coin battery for up to 250 hours. SEP suppresses transmissions of artifact data, which reduces power consumption.Type: GrantFiled: May 28, 2021Date of Patent: January 30, 2024Inventors: Kanad Ghose, Sandeep S. Mittal

Patent number: 11883177Abstract: Lactate threshold device (LTD) assists subjects in improving athletic performance and maximizing calorie burn. LTD digitizes the electrocardiogram (ECG) obtained from a chest belt with a first signal analyzer, and telemeters the ECG to a second signal analyzer. LTD uses a novel algorithm to convert the telemetered ECG from the time to frequency domain, utilizing a digital signal processing method called fast fourier transform based spectral analysis. LTD determines whether lactate threshold (LT) has been reached, and furthermore calculates heart rate, heart rate variability, and heart rate and power zones. LTD displays the determined variables on a local or remote display. Subject using LTD obtains feedback during a real-time exercise regimen in the field that has aerobic (below LT) and anaerobic (above LT) zones. By utilizing an exercise program with aerobic and anaerobic zones, both sprint and endurance fitness levels are improved, and weight loss potential is maximized.Type: GrantFiled: May 9, 2022Date of Patent: January 30, 2024Inventor: John Edward Scharf

Patent number: 11883178Abstract: A computer implemented method for detecting arrhythmias in cardiac activity including obtaining far field cardiac activity (CA) signals for a series of beats. For at least a portion of the beats, the one or more processors perform, on a beat by beat basis: a) identifying first and second feature of interests (FOI) from a segment of the CA signal that corresponds to a current beat; and b) classifying the current beat into one of first and second groups. The method also includes designating one of the first and second groups to be a primary group based on a relation between the first and second groups, and for the beats in the primary group, selecting one of the first and second FOIs as the R-wave FOI. The method also includes rejecting an arrhythmia detection based on the P-waves detected.Type: GrantFiled: February 18, 2022Date of Patent: January 30, 2024Assignee: Pacesetter, Inc.Inventors: Fujian Qu, Nima Badie, Jong Gill

Patent number: 11883180Abstract: Disclosed herein are methods, systems, and devices for identifying increased likelihood of non-ST elevation myocardial infarction (NSTEMI) in a patient based on ECG data. The methods can include determining based on the ECG data that the patient lacks ST elevation (STE) and that the patient exhibits a ventricular repolarization dispersion (VRD) score that exceeds a predetermined threshold value. The VRD score can be based in part on a T wave complexity ratio that serves as a temporal marker of VRD for the patient. Other markers of spatial and time qualities of repolarization can also be included in the VRD score. An elevated VRD score in the absence of STE can indicate a likelihood of NSTEMI in the patient and a potential major adverse cardiac event.Type: GrantFiled: October 14, 2020Date of Patent: January 30, 2024Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: Salah Al-Zaiti, Ervin Sejdic, Clifton W.

Patent number: 11883182Abstract: A system and a method is provided for assessing motion of a biological tissue of a subject including one or more superficial biological layers and a targeted biological layer. An optical perturbation is introduced within the one or more superficial biological layers but not within the targeted biological layer.
