n. a pump that replaces the natural heart
Wikipedia
An artificial heart is a device that replaces the heart. Artificial hearts are typically used to bridge the time to heart transplantation, or to permanently replace the heart in case heart transplantation is impossible. Although other similar inventions preceded it going back to the late 1940s, the first artificial heart to be successfully implanted in a human was the Jarvik-7 in 1982, designed by a team including Willem Johan Kolff and Robert Jarvik.
An artificial heart is distinct from a ventricular assist device designed to support a failing heart. It is also distinct from a cardiopulmonary bypass machine, which is an external device used to provide the functions of both the heart and lungs and are only used for a few hours at a time, most commonly during cardiac surgery.
Artificial Heart is the eighth studio album by rock musician Jonathan Coulton. After taking a long hiatus from songwriting after his successful 2006 Thing a Week project (with the exceptions of " Still Alive" and ten songs recorded between 2007 and 2009), Coulton started production on Artificial Heart after encouragement from John Flansburgh (of They Might Be Giants), also the album's producer. Unlike much of Coulton's previous work, Artificial Heart's original lyricism is largely non-comedic and contains few references to geek culture overall, instead opting for heavy themes of betrayal, commitment, abandonment, and surrender.
