Yorick, mascot of the FDA's Mechanics and Materials Laboratory, was created by engineer Ed Mueller. The plastic skeleton was outfitted with medical devices tested by the lab and sported the latest in approved medical devices. Popular with the public, Yorick was used to explain bionics and biomedical technology. Yorick was retired in 2003 and now resides in the Medical Sciences Division of the Smithsonian's Museum of American history. Yorick's enhancements include: cranial plate, silicone nose, carbon tooth root, inter-ocular lens, cochlear implant, heart valve, artificial heart, cardiac pacemaker, infusion port, vascular grafts, urinary sphincter prosthesis, artificial patella, bone plate, artificial tendons, bone growth stimulator, and artificial hip, knee, elbow, and finger joints.
