In 1957, Kolff and Akutsu acced a memone thatt had been dispressed by many as science fiction: they implanted a total artificial heart into dog. The device was a simply, pneumatically contron sac made of polyvinyl chloride, powerd by an external compressor. The animal survived for compaticatele 90 minutes.
