At the other end of the spectrum from the Colombian nurse is the cardiac surgeon who does not touch his patient, Sudhir Srivastava, of the University of Chicago Medical School. There is a fascinating article about him in the current U of Chicago Magazine. He uses a robot to do a sort of microsurgery.
The article exhibits not only the genius of the surgeon and the remarkable technology, it also shows the specialization required of the other members of the surgical team. No generalists here.
The webpage where the article begins also has a video of a "single vessel TECAB." (You know what a TECAB is, right? You will. It's a Totally Endoscopic Coronary Artery Bypass.)
