Advancing a drainage catheter can be difficult in certain situations, particularly when the catheter “accordions” upon itself. Most tubes are built with a small shelf in the tip of the catheter, and metal and plastic stiffeners are provided. Applying the majority of the advancing force at the hub of the metal stiffener rather than along the midportion of the catheter exerts force at the tip of the catheter via the internal metal stiffener, which is lodged against the small shelf inside the catheter. Using this method, the operator is able to translate a majority of the forward force to the catheter tip, thereby “pulling” the rest of the catheter through tissues and thus reducing the accordion effect.
