  • Patent number: 9775524
    Abstract: An apparatus and method of assessing a narrowing in a fluid filled tube having a fluid flow pressure wave having a backward-originating pressure component and a forward-originating pressure component without taking a flow velocity measurement, comprising: taking pressure measurements in the tube; separating the pressure components into the backward-originating pressure component and the forward-originating pressure component; identifying a time window when the differential of flow velocity (dU) is minimal or absent; and deriving the backward and forward pressure components for pressure measurements taken in at least the time window.

  • Publication number: 20160206214
    Abstract: Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to assess the severity of a stenosis in the coronary arteries without the administration of a hyperemic agent.

  • Publication number: 20130345574
    Abstract: A system and method for characterising a narrowing in a fluid filled tube, the system comprising: a probe having a first measurement sensor to take an instantaneous measurement at different locations along the tube; a mechanism to draw the probe through the tube; a position measure to provide location data relating to the location at which a respective instantaneous measurement is taken by the first measurement sensor; a processor to calculate, from the instantaneous measurements, a characteristic of the tube at different locations along the tube.
