Perfusion pump

An improved perfusion pump that could keep organs or tissues alive for extended periods was developed. This device, called an artificial heart, enhanced the process of perfusion by being more efficient and germ-proof. As proof, he kept piece of embryonic chicken heart alive and growing for over thirty-four years, much longer than the normal life expectancy of a chicken.
