摘要:
The invention relates to an aortic cannula for delivering fluid, especially blood, into a vessel of the human body, particularly the aortic arch. Said aortic cannula comprises an elongate basic cannula body into which the fluid is directed, an orifice from which the fluid is discharged at the distal end of the basic cannula body in a basic direction of flow defined by the basic cannula body, as well as at least one first deflecting element and a second deflecting element that are disposed in front of the orifice within the flow path of the fluid. Said at least one deflecting element and said second deflecting element are respectively provided with a passage opening that is aligned relative to the orifice, and a deflecting area which redirects the portion of the fluid, which does not flow through the passage opening. The area of the passage opening of the first deflecting element is greater than area of the passage opening of the second deflecting element, and/or the angle of deflection of the deflection area of the first deflecting element is greater than the angle of deflection of the deflection area of the second deflecting element which is arranged behind the first deflecting element.
