Abstract
The present invention discloses a method to move a magnetic capsule linearly both horizontally and linearly in a very controllable fashion, wherein the direction of a combined external magnetic field, the force experienced by the magnetic capsule, the movement direction of the capsule and magnetic direction of the magnetic capsule can be all aligned in parallel to each other.
Claims8
A method to navigate a magnetic capsule, comprises
- introducing the magnetic capsule into a target area, said magnetic capsule has a longitude direction and the magnetic dipole placed inside the magnetic capsule has a magnetization direction coincide with the longitude direction of the magnetic capsule;
- placing the magnetic capsule in a first orientation, including its magnetic direction in a z direction;
- providing an external magnetic control system comprising two magnetic balls, placed on opposing sides of the target area;
- and
- rotating the magnetic capsule in the target area to adopt a second orientation while maintaining its position in xyz coordinates.
