MAGNETOMOTIVE STATOR SYSTEM AND METHODS FOR WIRELESS CONTROL OF MAGNETIC ROTORS

摘要

A system for increasing diffusion of a pharmaceutical composition in a body lumen of a subject includes a plurality of individual magnetic rotors, a magnet having a magnetic field and a gradient, and a controller configured to position and rotate the magnetic field and to control the gradient in a manner to cause the individual magnetic rotors to form ensembles in which each individual magnetic rotor generally simultaneously rotates and travels in a same direction, and to cause the ensembles to simultaneously rotate and travel toward a therapeutic target in the body lumen to collectively create hydrodynamic forces that generate turbulence and increase diffusion of a pharmaceutical composition capable of inducing a desired therapeutic effect in the body lumen.
