Multi-lumen aortic cannula

摘要

Aortic cannula comprises a first lumen (3) having an outlet opening (31) with an edge lying in the opening plane. A concave wall region is provided inside the first lumen for deviating blood in the direction of the outlet opening. The outlet opening is arranged on the cannula base body (2) with respect to a second lumen (4) so that the opening plane of the outlet opening has an angle of 60-120[deg], preferably 80-100[deg], with the longitudinal axis of the section penetrating an occlusion balloon (1). The occlusion balloon is flattened in the regions which contact the aorta inner wall. Preferred Features: The occlusion balloon has a hollow cylindrical shape and the outer casing surface of the balloon forms the regions in contact with the inner wall of the aorta.
