You gotta have faith

A couple of nuns who were nursing sisters had gone out to the country to minister to an outpatient. On the way back they were a few miles from home when they ran out of gas. They were standing beside their car on the shoulder when a truck approached.

Seeing ladies of the cloth in distress, the driver stopped to offer his help. The nuns explained they needed some gas. The driver of the truck said he would gladly drain some from his tank but he didnt have a bucket or can.

One of the nuns dug out a clean bedpan and asked the driver if he could use it. He said yes and proceeded to drain a couple of quarts of gas into the pan. He waved goodbye to the nuns and left.The nuns were carefully pouring the precious fluid into their gas tank when the highway patrol came by.

The trooper stopped and watched for a minute, then he said: "Sisters, I dont think it will work, but you sure have faith!"

Artificial heart implant

In 1957, the first total artificial heart implantation in an animal kept a dog alive for 90 minutes in a pioneering experiment at the Cleveland Clinic by Dr. Willem Kolff and Dr. Tetuzo Akutsu. Blood pumps for left and right circulation were implanted in the chest of a 20.7-kg dog, beating at the rate of 100 with an aortic pressure of 70/50 mm Hg. Akutsu was in Kolff's laboratory as a thoracic surgeon interested in cardiopulmonary bypass when Kolff asked him to make the device. The idea was prompted by an address by Dr. Peter F. Salisbury who had made, but not implanted, hydraulically activated twin pumps. Advice was contributed by Dr. Selwyn McCabe at the Mark Company, who had also fabricated an earlier artificial heart. Akutsu molded the four-chamber blood pump from “Tygo-Flex” PVC.
