A length of invasive flexible or semi-flexible tube designed to be attached to a surgical instrument (e.g., surgical stapler) to direct irrigation fluids to the surgical site; it may in addition be intended to allow for introduction of air to facilitate procedures such as staple line leak testing, however it is not intended for medical gas insufflation or suction. It is intended to be used in combination with devices that do not have an integrated irrigation channel. This is a single-use device.
