Abstract
A venous return catheter is provided having a first diameter distal portion suitable for insertion in a vena cava, a second, larger diameter proximal portion, and a transition portion forming a smooth transition between the first and second diameter portions. Drainage openings are provided in both the proximal and distal catheter portions. The catheter is of unitary construction, having a smooth bore through its entire length. It is also constructed from a soft, resilient material, but is reinforced with a harder, stiffer material in the region of the proximal drainage openings. The catheter may also be provided with wire reinforcement. The catheter is manufactured by a dip-molding process utilizing a male mandrel as a form.
