\nToday’s Thingamajig is an artificial heart valve, from the medical instruments collection.\u00a0 This one was given to us by Dr. Don Chapman, and was accompanied by three small pacemakers.\u00a0 I included the quarter for scale (I picked Nevada because it’s one of the most picturesque of the state quarters.\u00a0 I was a horse-crazy little girl).
\nThere are several different types of artificial heart valve.\u00a0 Other types include one with a rotating disk, and several variations of ball valves, which operate a little like the tip of a ballpoint pen.\u00a0 This one is called a “bileaflet” valve because it has two semicircular flaps.\u00a0 A good article with pictures of the other types was published by The Annals of Thoracic Surgery in “Mechanical Heart Valves: 50 Years of Evolution<\/a>.”
