Implanted insulin pump is refilled with magnetic capsules that you swallow

Most people with diabetes need at least two shots of insulin per day, but to to ease this burden, scientists are working on an implantable robot to administer the medication. A team of Italian researchers recently published a study in the journal Science Robotics that outlines a two-component system called PILLSID, which includes an implantable insulin pump that sits in the abdomen area and ingestible magnetic hormone capsules to refill it. When patients need to reload the pump, they swallow a capsule, which is then pulled through the digestive system by magnets inside the insulin device. The device, roughly the size of a flip phone, catches the capsule with a tractable needle, rotates it into a certain position and then extracts the hormone. The capsule continues to move naturally through the digestive track and eventually leaves the body.
