Abstract
A method for controlling a magnetic catheter by using a magnetic-field-generated magnetic annulus is disclosed. The magnetic catheter has a free end provided with a magnetic member. A resultant magnetic field between at least two magnets generates a magnetic annulus. The magnetic catheter is placed into the magnetic annulus, so that the magnetic member is affected by the magnetic force from the magnetic annulus to guide the magnetic catheter to perform a preset motion. The magnetic catheter has a flexible front section, so that the flexible section can perform a bending motion when led by the magnetic member. The resultant magnetic field is generated by arranging the two magnets with their like poles facing each other, so that the magnetic member is thrust when entering the magnetic annulus. This facilitates the bending motion of the flexible section.
