The MARS surgical platform at the Luis Tisne hospital in Santiago allows surgeons to "attach a small magnet to organs, like the liver, and use robotic arms with high powered magnets on the patient’s belly to manipulate organs out of the way," according to Levita Magnetics, the California-based start-up that created robot.

The system also "gives the surgeon control of the camera, which allows for better visualization, it is much more stable. And in surgery, seeing is everything," said Alberto Rodriguez-Navarro, doctor and founder of Levita Magnetics, the California-based start-up that developed the MARS platform.
