The heart-lung machine took over the functions of the heart and lungs during surgery by supplying oxygenated blood to the brain, helping to inaugurate the era of open heart surgery.
In 1952 DeBakey successfully repaired an aortic aneurysm by replacing the damaged abdominal segment with a graft from a cadaver.
