Abstract
A needle protector that protects the tip or distal end of a cannula, a trocar, or a cannula/trocar combination, is provided by an extruded tubing that has at least a section thereof that includes one or a plurality of protrusions or protuberances that are configured in a given fashion so that there is a slight bend created at that section of the tube, when the tube is fitted onto a cannula or trocar with the protrusions coming into contact with the outer diameter surface of the cannula or trocar. This results in friction contact between the protrusions and the cannula or trocar to maintain the tube protector in place relative to the cannula or trocar. The protrusions may be punched or lanced in the tube to a given depth towards the interior of the tube to establish a given friction contact.
