Victorian artificial arm. “Made from steel and brass, the elbow joint on this artificial arm can be moved by releasing a spring, the top joint of the wrist rotates and moves up & down, and the fingers can curl up and straighten out. The wearer may have disguised it with a glove. Among the most common causes of amputation throughout the 1800s were injuries received as a result of warfare.” - Science Museum

Sapien is the first heart valve approved in the United States which doesn't require open heart surgery.
