What is tapered medical tubing?
Extrusion cross sections can vary in size along their length. Such tapered extrusions are commonly used to create variable stiffness from proximal to distal ends or to ease connections at the proximal end. Inside diameters can remain constant, while the outside diameter changes along the end.
Tapered tubing, sometimes referred to as bump tubing, is an increase in the tubing diameter. This allows for smooth joining of differently sized medical devices or tubes.
