The MIT team envisions that its robotic system could be installed at smaller hospitals and remotely guided by trained surgeons at larger medical centers. The system includes a medical-grade robotic arm with a magnet attached to its wrist. The robotic system, whose movement is controlled through magnets, is designed to remotely assist in endovascular intervention — a procedure performed in emergency situations to treat strokes caused by a blood clot. MIT engineers have developed a telerobotic system to help surgeons quickly and remotely treat patients experiencing a stroke or aneurysm. From there, an operator watched the video while using the joystick to remotely steer the wire through the vessels.
