To make this, a piece of polyethylene tubing size 190 or 160 is grasped in both hands and given a quick pull. This causes the polyethylene to stretch the taper. Polyethylene in this manner stretches much like heated glass tubing, forming a taper. The tubing is then cut with a bevel at the narrow portion of the taper. A needle may then be inserted into the lumen
