Patent ID: 7473245

Claim:
An aortic cannula for delivering fluid into a vessel of the human body, the aortic cannula comprising: a. an elongate cannula body that is insertable into the vessel of the human body, into which the fluid is directed, with 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 cannula body; and b. at least a first deflecting element and a second deflecting element, i. which are arranged in front of the orifice within the flow path of the fluid, ii. which each have a passage opening aligned relative to the orifice, and iii. which each have a deflecting area, which redirects a portion of the fluid which does not flow through the passage opening, iv. wherein the area of the passage opening of the first deflecting element is greater than the area of the passage opening of the second deflecting element, and/or wherein the angle of deflection of the deflecting area of the first deflecting element is greater than the angle of deflection of the deflecting area of the second deflecting element, which is arranged behind the first deflecting element in the basic direction of flow.
