Abstract
A method and apparatus for generating a controlled torque of a desired direction and magnitude in an object within a body, particularly in order to steer the object through the body, such as a catheter through a blood vessel in a living body, by producing an external magnetic field of known magnitude and direction within the body, applying to the object a coil assembly including preferably three coils of known orientation with respect to each other, preferably orthogonal to each other, and controlling the electrical current through the coils to cause the coil assembly to generate a resultant magnetic dipole interacting with the external magnetic field to produce a torque of the desired direction and magnitude.
