I started researching artificial heart devices many years ago. If some of you remember I was relentlessly pursuing the Jarvik-7. Much of what interest me is the deceptively simple yet complex design of these machines. The valves are specially designed to intake blood and drive it out without any failure or reverse flow on the system. A bladder driver filling up precisely and simulating the heart is an amazing achievement  of science and art. This display is a custom built lab type stand that holds the heart and vessel in close proximity. The mounted pump powers the heart cycle in an endless loop. This simple gesture is a gift that saves a life. The pump eerily mimics human breath as is flows in and out. A rather meditative reflection of life, death and evolution.
