1. An arterial cannula connectable to a heart-lung machine for supplying a human patient with oxygen-rich blood, comprising
a tubular body having a front end region for positioning in a region of the aortic arch of the patient, a main region, and a rear end region for connection to a supply side,
wherein the tubular body comprises a lumen,
wherein the tubular body is made of a flexible material,
wherein the length of the tubular body is dimensioned to facilitate placement of the cannula in a region of the femoral artery of the patient and extends into the region of the aortic arch,
wherein the tubular body provides a supply flow of oxygen-rich blood to the aortic arch,
and wherein perforations are provided in the front end region of the tubular body,
the front end region of the tubular body is at least partially pre-curved following the shape of the aortic arch,
an insertion aid located inside the tubular body for placing the cannula is slidable into the tubular body or withdrawn from the tubular body after the cannula has been placed,
