The present application provides an arterial cannula system for transporting blood from an extra-corporeal pump to a patient's femoral artery, and aorta comprising first and second cannula portions. The first cannula portion (30) has a proximal portion (26), a distal portion (29), an intermediate portion (38), and is configured for insertion through the femoral artery. It includes a first lumen (31) extending from the proximal portion to the distal portion to deliver cardio-plegia fluid, a second lumen (33) communicating with an expandable occluding member (34) at the distal end portion to inflate the occluding member to occlude blood flow, and a third lumen (44) extending from the proximal portion to the intermediate portion to transport blood from the extra-corporeal pump to the femoral artery. The second cunnula portion (50) is configured for insertion into the subclavian artery so that an opening (56) in the distal portion (58) is in communication with the aorta. A lumen extending through the second cannula portion is in communication with the opening to transport blood from the extra-corporeal pump to the aorta.
