An electromagnetic robot for navigating medical devices

The Navion, a clinical-scale electromagnetic navigation system, is the result of over 20 years of development. Its motivation began in 2003 with the goal of controlling the motion of magnetic microrobots; however, its first clinical use is proving to be for guiding magnetic catheters, guidewires and endoscopes.
