CATHETER WITH TWO-WAY VALVE

摘要

A catheter cube (12) is made of soft, flexible material and is formed with closed end (18). A valve (10) formed by a single slit through the tubing wall is of such length that the valve will open only upon application of predetermined pressure differentials. A removable stiffener member (16) is positioned within the catheter and abutting the closed end to push the catheter into a body vessel when inserting.
