A 64-year-old Illinois man left the hospital Thursday without a human heart in his body, but very much alive.
Leroy Haynes, a retired letter carrier from Monee, Ill., walked out of Advocate Christ Medical Center on Thursday after more than three months of treatment for end-stage heart failure, Fox Chicago reports.
Replacing Haynes' failing human heart is a completely artificial device powered by a portable pneumatic pump, a major advance that allows Haynes to live comfortably at home, the Chicago Sun-Times reports. He previously had an implanted battery-powered pump that supported his weak heart, but is now the first Illinois resident to have an entirely artificial device.
