A long flexible or rigid tube with an atraumatic tip intended to be used during an endoscopic/laparoscopic procedure to provide access for the administration of a haematological concentrate and/or haemostatic agent (e.g., thrombin, platelet concentrate, polysaccharide) to a bleeding surgical site, typically to facilitate haemostasis and healing. It is designed to be inserted into the body percutaneously, via a port or rigid endoscope (e.g., laparoscope). It may have a single channel, to administer one product, or dual channels for co-administration of two different agents simultaneously; a channel for connection to a gas pump for spraying may be incorporated. This is a single-use device.
