ABSTRACT:
An aortic balloon occlusion cannula for the occlusion of the aorta ascendens during cardiac surgery including a cannula containing several lumina that are separated from one another. The cannula carriers two dilatable occlusion balloons positioned at a distance from each other, one of the balloons being neighbored to the distal end of the cannula which faces away from the heart and each of the balloons being connected to its own lumen which enables its dilation in independence from the other balloon. The cannula is insertable through the lefthand ventricle of the heart and through the valvula aortae and includes at least one further lumen. The further lumen being connected on the distal side, facing the body, of the distal occlusion balloon to the lumen of the aorta and is adapted to be connected to an extracorporal blood supply device. An additional separate lumen is provided in the cannula and forms a return conduit for liquid and opens on the proximal side of the proximal occlusion balloon.
