  • Patent number: 10426923
    Abstract: A catheter tip having a spring element that imparts longitudinal flexibility, pushability and radial rigidity to the catheter tip, thereby improving deliverability, is provided. The spring element also provides radial support to the distal edge of the catheter tip. The spring element may taper distally, but may have a substantially constant inner luminal diameter. The spring element may be partially covered or embedded, leaving its distal end exposed. The spring element may also include spaced coils in a proximal region. The apparatus may be used with any interventional catheter system, but is particularly suitable for use with balloon-expandable stent systems and balloon-angioplasty systems, where flexibility of the catheter tip and minimal flaring of the distal edge of the catheter tip is desirable.

  • Patent number: 9750463
    Abstract: Embodiments of the disclosure are directed to a system for analysis of respiratory distress in hospitalized patients. The system performs multi-parametric simultaneous analysis of respiration rate (RR) and pulse oximetry (SpO2) data trends in order to gauge patterns of patient instability pertaining to respiratory distress. Three patterns in SpO2 and RR are used along with LOWESS algorithm and Chauvenets criteria for outlier rejection to obtain robust short term and long term trends in RR and SpO2. Pattern analysis detects the presence of any one of three pattern types proposed. Further, a learning paradigm is introduced to find unknown instances of respiratory distress. This algorithm in conjunction with the learning model allows early detection of respiratory distress in hospital ward and ICU patients.

  • Publication number: 20150105641
    Abstract: A human body support, such as a chair, has a plurality of support segments that are arranged in an array. Each support segment has a protrusion elevation that is independently variable and controllable in its distance of protrusion elevation against the supported human body. A sensor is connected to a human body on the support and senses a human body parameter that can indicate the presence of drowsiness. A controller analyzes the sensed parameter to detect whether the sensed parameter is within a range indicating the presence of drowsiness. The controller applies a wave of varying segment protrusion elevation against the human body in response to the detection of drowsiness. The wave progresses in a direction from an inferior location on the human body toward a more superior location. Alternatively, a wave of electrical stimuli is applied by similarly positioned electrodes and causes periodic tightening and relaxing of proximate muscles.

  • Publication number: 20150011854
    Abstract: Various embodiments of methods and systems for continuous transdermal monitoring (“CTM”) are disclosed. One exemplary method for CTM begins by monitoring an output signal from an accelerometer. The accelerometer output signal may indicate acceleration and deceleration of a body part of a user, such as the user's wrist. Based on the accelerometer output signal, it may be determined that the body part of the user has decelerated to a minimum, e.g., substantially zero. With a determination that the body part has decelerated to the minimum, e.g., substantially zero, or has not accelerated beyond the minimum, e.g., substantially zero, the method may determine a reading from a pulse oximeter associated with the accelerometer. Advantageously, the pulse oximetry reading, or a reading from other sensors associated with the accelerometer, may be optimally accurate as motion artifact may be minimized. The pulse oximetry reading may be recorded for later query and/or rendered for the benefit of the user.

  • Patent number: 8840562
    Abstract: Methods and systems are provided for using time-frequency warping to analyze a physiological signal. One embodiment includes applying a warping operator to the physiological signal based on the energy density of the signal. The warped physiological signal may be analyzed to determine whether non-physiological signal components are present. Further, the same warping operator may be applied to signal quality indicators, and the warped physiological signal may be analyzed based on the warped signal quality indicators. Non-physiological signal components, or types of non-physiological noise sources, may be identified based on a comparison of the physiological signal with the signal quality indicators. Non-physiological signal components may also be identified based on a neural network of known noise functions. In some embodiments, the non-physiological signal components may be removed to increase accuracy in estimating physiological parameters.
