In a small, unassuming factory in Kyoto, one firm is helping save lives. That firm is run by Masatoshi Takeda, who invented a method to build hyper-accurate replicas of the organs of patients, from those with heart defects to liver cancer, who require difficult surgical procedures. Doctors use the replicas to perform simulated surgeries, increasing the chance of success in the operating room. Created hand-in-hand with doctors, Takeda's technology is changing the face of surgery as we know it.
