I love it when my whackjob ideas are vindicated. In Singapore, a woman now has a non-beating artificial heart similar to the one I described.
Well, actually, no. The design she got was different, according to sources at MIT. Hers is a continuously pumping bar, my design calls for a heart-shaped pump that speeds up and slows down. Still, proof that a beat isn't strictly necessary does leave me encouraged.
Our best wishes to Ms. So'ot, I hope her new heart allows her to live a long life.
