A system and a method for measuring volumetric flow in arteries

Abstract

An arterial flow measurement system comprising: a catheter tube being which may be configured to be inserted into an artery, the catheter tube having longitudinal axis, a proximal end and a distal end, a first inner lumen providing fluid communication along the longitudinal axis of the catheter tube, a first opening (input opening) configured to provide fluid communication from the outside of the catheter tube and into the first inner lumen through a side wall of the catheter tube, a fluid guide element having an insertion state where the fluid guide element has a first cross-sectional diameter, and in a measuring state where the fluid guide element has a second-cross-sectional diameter, where the fluid guide element is configured to guide at least part of an arterial flow surrounding the fluid guide element into the first opening, a conversion element, where the conversion element is connected to the fluid guide element allowing a user to selectively transform the fluid guide element from an insertion state to a measuring state, and vice versa; and where the arterial flow measurement system comprises a flowmeter configured to measure the flow of a fluid wherein the flowmeter is in fluid communication with the first inner lumen of the catheter tube
