A continuous-flow artificial heart:

Frazier and his team have implanted pairs of commercially available ventricular-assist de-vices* into calves that had their hearts removed. The researchers say the de-vices* were able to pump blood and respond to the animals’ needs based on their activities. “You put this in cattle and they stand up and moo and eat and wonder why everyone is looking at them so weird,” says William Cohn, a collaborator on the research and director of minimally invasive surgical technology at the Texas Heart Institute.

…Cohn hopes that in the future, artificial heart technology will become much safer and easier to use, broadening the potential pool of patients. “It wouldn’t surprise me if at the 2050 Olympics, there were standard and modified [competitor] divisions,” he says.

Ahhh, life in the twenty-first century.
