The invention provides a co-axial dual lumen catheter having a main section, a tip section, and a U-shaped proximal portion extending from the main section, and ending at a junction where intake and outlet tubes are connected to the proximal portion. An inner tube extends from the junction to the tip of the catheter to define a return lumen, and combines with outer tubes in the main section and the proximal portion to define an intake lumen. The inner tube is thin walled relative to the wall thickness of a first outer tube used in the main section, and a second outer tube used in the proximal portion has a greater cross-sectional area than the first outer tube. A proximal end structure is also described in which the intake and outlet tubes extend generally parallel with the main body and to one side of the main body.
