Abstract (en)
[origin: WO9902209A1] The invention relates to a two lumen cannula (1) comprising an external cannula (2) designed as a perforation and incision cannula, and an internal cannula (3) which can slide in the external cannula and which, in a forward position, sticks out of the latter. These two cannulas (2, 3) are both bound to a respective blood hose (4, 5). The inventive two lumen cannula must be designed so that blood recirculation and blood vessels damage are avoided to a large extent. This is achieved by means of the internal cannula (3) being a flexible plastic cannula which, when in a forward position, sticks out so much with its forward end (6) of the external cannula (2) that no substantial recirculation of the blood can take place.
