  Dick Cheney has half of one. He has a left-ventricular assist device, which has one pump, but still has a heart that does part of the work. The proposed devices in the PopSci article are two of those pumps together, replacing the heart's functions altogether. These have been implanted into cows and work fine, but haven't worked their way through the FDA yet for non-trial use in people.
