Abstract

The closed distal portion of a catheter tube has a two-way, three-position valve that infuses fluid in substantial alignment with the longitudinal axis of the distal portion of the catheter tube. An endwall having material properties determined independently from the material properties of the circumferential outer wall of the catheter tube is attached to the circumferential outer wall, directly or by way of the intermediate circumferential outer walls of a hollow distal extension for the catheter tube. A slit having opposed abutting faces is formed through the endwall. The endwall is perpendicular to or inclined relative to the longitudinal axis of the distal portion of the catheter tube and is a planar or arcuate structure of uniform or nonuniform thickness. In multiple lumen catheter devices an endwall with a slit is provided at the distal end of each individual lumen that is to be closed and valved.
