ABSTRACT:
A dual lumen catheter is provided having an elongate body defining coaxial intake and return lumens and a junction containing a proximal end of the body with parts of the lumens in the junction constrained in side-by-side relationship. First and second connecting tubes are engaged in the junction and extend generally longitudinally away from the main body. The junction provides fluid continuity between the first connecting tube and the intake lumen and between the second connecting tube and the return lumen to permit the catheter to be used for simultaneous dual flow. The distal end of the catheter includes a conical transition portion at which the exterior diameter of the dual lumen main catheter section is smoothly reduced to that of an open-ended, single lumen cylindrical tip section of lesser diameter.
