North Carolina State University mechanical engineering student Andrew Richards came up with a way for an artificial dynamic heart system to keep the heart of a pig beating outside of the body. The dynamic heart system is able to pump fluid through the pig’s heart so that it works in a very realistic manner. The machine is created using a pressurized saline solution. This solution allows researchers to monitor the pumping heart internally to find out which surgical methods work for repairing heart valves. Researchers are able to conduct pig heart experiments by making a deal with pork processing facilities.
