1. A system for moving a capsule within the body of an animal comprising:
- a capsule dimensioned and shaped to move within the body of the animal;
mechanically coupled to the capsule, an anisotropic magnetic component to orient the capsule in relation to an applied magnetic field;
a detector to determine the location of the capsule within the body; and
a magnetic field generating system external of the body responsive to the detected location of the capsule for generating a three dimensionally oriented field within the body to move the anisotropic magnetic component and thereby the capsule within the body.

Abstract
This invention discloses such a convenient navigation system and navigatable capsules which are useful for remote-controlled imaging, biopsy and programmable drug release within the body of an animal. The components of the system comprise a capsule dimensioned and shaped to move within the body. An anisotropic magnetic component is mechanically coupled to the capsule to move or orient the body in relation to an applied magnetic field, and a magnetic field generating system external of the body generates a three dimensionally oriented magnetic field within the body to move or orient capsule.
