Operating room staff watch video monitors as surgeon Volkmar Falk performs a coronary artery bypass graft using Intuitive Surgical's tele-manipulated surgical manipulator system. Herzzentrum, Leipzig, Germany. Falk can hear his assistant surgeon in the operating room via a room speaker overhead. He speaks to him over the microphone taped to his surgical garb, which is in turn piped into the operating room. While Falk is sitting at the console, he is not sterile and therefore isn't in a surgical gown as are the assistants who are with the patients. Stefan Jakobs, the assistant surgeon, watches the monitor to follow Falk's progress in the operation.
