  • Patent number: 10687781
    Abstract: Hemodynamic monitoring systems and methods are disclosed including a device comprising a first sensor configured to measure a velocity of blood flow in an adjacently-located portion of a superior vena cava of a mammalian patient using ultrasound waves; a second sensor configured to measure respiratory cycle data of the mammalian patient; and a computer configured to process the measured velocity of blood flow and the measured respiratory cycle data to provide hemodynamic parameters corresponding to the mammalian patient.
    Type: Grant

  • Patent number: 9743994
    Abstract: A method for determining the location of a medical device within a body is provided. The method includes transmitting from the medical device an acoustic signal; receiving with the medical device a reflected acoustic signal; advancing the medical device based on a first algorithm, the first algorithm including a first weighting factor and a first feature extracted from the reflected acoustic signal; determining a first location of the medical device based on the first algorithm; and moving the medical device to a second location based on a second algorithm, the second algorithm based on the determined first location and including at least one of a second weighting factor and a second feature extracted from the reflected acoustic signal. Also disclosed are systems and devices for performing the methods described herein.
