Abstract
The present application provides an arterial cannula system for transporting blood from an extracorporeal pump to a patient's femoral artery and aorta comprising first and second cannula portions. The first cannula portion has a proximal portion, a distal portion, and an intermediate portion and is configured for insertion through the femoral artery. It includes a first lumen extending from the proximal portion to the distal portion to deliver cardioplegic fluid, a second lumen communicating with an expandable occluding member at the distal end portion to inflate the occluding member to occlude blood flow, and a third lumen extending from the proximal portion to the intermediate portion to transport blood from the extracorporeal pump to the femoral artery. The second cannula portion is configured for insertion into the subclavian artery so that an opening in the distal portion 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 extracorporeal pump to the aorta.
