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, in conjunction with an applicator such as a syringe [not included]. It is designed to be inserted into the body percutaneously, via a port or endoscope/laparoscope. It may have a single or dual-channel(s) for administration of one or two agent(s); a channel for connection to a gas pump for spraying may be incorporated. This is a single-use device.
