This little bug is called the HeartLander, a tiny little caterpillar-esque robot developed by the Carnegie Mellon University’s Robotics Institute in Pittsburgh. Inserted via keyhole surgery, the HeartLander crawls across the surface of the heart to administer drugs or attach medical devices. Apparently this invention could revolutionalize the treatment of cardiac patients while making the rest of the world sick at the mere sight of it. More details and a picture of the robot itself right after the jump.
