Magnetic Navigation System for Diagnosis, Biopsy, and Drug Delivery Vehicles
The invention discloses a magnetic navigation system and navigable capsules that are useful for remote-controlled imaging, biopsy, and programmable drug release within the body of an animal. The system includes a capsule dimensioned and shaped to move within the body; an anisotropic magnetic component coupled to the capsule to orient it relative to an applied magnetic field; a detector to determine the location of the capsule within the body; and a magnetic field generating system external to the body that is responsive to the detected location of the capsule. The detector senses the position of the capsule and the feedback of the position information is utilized for controlling the magnetic field generating system to guide the capsule as it moves within the body. The capsule can carry devices for imaging, biopsy, and/or drug release.
