Guided by a miniature camera connected to a 3-D monitor, surgeons use the da Vinci to operate by remotely manipulating tiny robotic arms. This is safer and far less invasive than regular surgery. It reduces the patient’s recovery time, post-operative discomfort, scarring and infection risk. In the three months ended March 31, 2011, Intuitive earned $104.1 million, or $2.66 a share.
