ABSTRACT:
A catheter assembly is provided for delivering a diagnostic fluid to a diagnostic site within the vascular system of a patient comprising an elongated central tube that can be routed into and through a vascular system of a patient, the tube including a tube proximal end and a tube distal end, a flexible sleeve defining a space between the interior surface of the sleeve and an exterior surface of the central tube, the sleeve comprising a sleeve proximal end sealably connected to the exterior circumference of the central tube. The sleeve extends along a length of the central tube from the sleeve proximal end to a sleeve distal end, the central tube defining one or more openings that extend through a wall of the central tube so that the interior of the central tube is in fluid communication with the interior of the sleeve.
