Tapered medical tubing is a type of medical tubing that has a gradually decreasing diameter along its length. This shape is achieved through a process of extrusion or drawing, in which the tubing is stretched and pulled to create the tapered shape. The taper can be a gradual slope or a more aggressive cone shape, depending on the specific requirements of the medical device or procedure.

Funnel or bump tubing are all different names for the same type of medical tubing that has a gradual increase in diameter along its length, rather than a gradual decrease as in tapered tubing. The tubing typically starts with a smaller diameter at one end and gradually increases to a larger diameter at the other end, creating a bump or funnel shape.
