ABSTRACT:
A multi-lumen coaxial catheter and method for making such a catheter are provided. The catheter includes three generally coaxially disposed catheter tubes having proximal and distal portions and defining three coaxial lumens. The distal portions are attached to the proximal portion of a sleeve. The distal portion of the sleeve extends outwardly from the proximal portion of the sleeve around the inner catheter tube to form a tip. The proximal portions of the catheter tubes are attached to a hub having passageways in fluid communication with the lumens extending longitudinally within the catheter tubes. The passageways are further in fluid communication with extension tubes also attached to the hub.
