APPARATUS, SYSTEM AND METHOD FOR MEASURING VOLUMETRIC FLOW OF BLOOD IN A VESSEL

摘要

A device for use in measuring a characteristic of liquid flow in a vessel includes a flexible elongate tubular element having proximal and distal extremities and having a wall defining a passage extending therethrough. A coil spring carried by the distal extremity of the flexible elongate element has a distal extremity that carries a transducer. Conductive means connected to the transducer extends interiorly of the coil spring and of the passage in the flexible elongate tubular element.
