Wiggling magnetic micro-robot goes after kidney stones.

Wiggling magnetic micro-robot goes after kidney stones. “Once in the body, the filament can be imaged via ultrasound, and moved by an external robotic arm equipped with a rotating magnet at the end. As that magnet rotates, the filament likewise wiggles back and forth, making its way through the urinary tract by pushing off against its inner walls. Upon reaching the kidney stone, the filament is stopped. It can then be held in place for several days via an external magnetic patch that’s adhered to the skin.” ~ learn more
