Penn State College of Medicine says a new federal grant will help them move closer to developing an implantable artificial heart. College officials say they are getting more than three-million-dollars from the National Heart, Lung, and Blood Institute to work on a heart that can operate wirelessly and reliably. Doctors say the device could solve the lack of available hearts for people who need transplants. One advantage of PSCM’s proposed design is its ability to conform to the anatomy of smaller patients.
