From the article: 'The tools include a snakelike robot that could enable surgeons, operating in the narrow throat region, to make incisions and tie sutures with greater dexterity and precision. Another robot, the steady-hand, may curb a surgeon's natural tremor and allow the doctor to inject drugs into tiny blood vessels in the eye, dissolving clots that can damage vision."
