  • Vascular impedance measuring device and method of determining impedance
    Patent number: 10842385
    Abstract: A vascular impedance measuring device may comprise a processing component capable of processing raw pressure and flow wave data and a pressure measuring component capable of providing pressure wave data from a specified point in a vessel and forwarding the pressure wave data to the processing component. The device may further include a flow measuring component capable of providing flow wave data from the specified point or a point near the specified point in the vessel and forwarding the flow wave data to the processing component. The processing component processes the raw pressure and flow wave data to produce an estimation of vascular impedance of the vessel from the specified point of measure and may provide data to a feedback system for therapy.
