A sterile, rigid tube designed to be surgically inserted, temporarily, into a peripheral blood vessel to function as a channel for the transport of irrigation fluid (e.g., saline, heparin solution) during open vascular surgery. It is typically made of metal with a shaped/bulbous tip (e.g., cone-, olive-shaped) and may be intended to be bent into shape; as it is a rigid device it is not intended to be advanced more than a minimal distance within the lumen of the blood vessel. This is a single-use device.
