  • Device and method for quantifying edema
    Patent number: 8425433
    Abstract: The preferred embodiments of the present invention are directed at a device that provides a reliable, accurate and quantifiable measure of a patient's edema. The device improves on the current method of digital manipulation by evaluating the pitting phenomena in a user-independent manner. The output of the device allows a physician to categorize edema into at least ten different levels of severity. The systems of the present invention provides the ability to distinguish between tissues of varying viscosity.
    Type: Grant
