Denton Cooley: I was operating with a surgeon who himself was handicapped. He had had a spinal cord tumor. He had one good hand, which was I think his left hand, which he used to operate. And he had one other arm, that was in sort of a brace. We had a patient with an aneurysm here, just under his breast bone. And I remember so well, we got the man anesthetized — he was actually bleeding when he got in the operating room — had the man anesthetized, and this surgeon reached down and pulled up the breast bone, and the blood hit the ceiling, and he put his finger in the hole in the aorta, and so he was completely immobilized. Because he had this other arm that he couldn’t do much with, and so he said, “Cooley, it’s your operation now. See what you can do to get my finger out of the hole.” And that was the way that came about. I figured out a way to patch up the hole in the aorta, and the patient survived. But I remember it was a task that was way beyond my experience at the time. And I wasn’t prepared for anything that difficult.
