Magnetic navigation system for the precise helical and translational motions of a microrobot in human blood vessels

Abstract

Different magnetic navigation systems (MNSs) have been investigated for the wireless manipulation of microrobots in human blood vessels. Here we propose a MNS and methodology for generation of both the precise helical and translational motions of a microrobot to improve its maneuverability in complex human blood vessel. We then present experiments demonstrating the helical and translational motions of a spiral-type microrobot to verify the proposed MNS. (C) 2012 American Institute of Physics. [doi:10.1063/1.3671411]
