Abstract
Magnetically propelled capsule endoscopy provides for the medical examination and treatment of the gastrointestinal tract, reproductive tract, trachea, lungs, vascular system or any accessible body cavity. The capsule will be steered throughout the system by an external magnetic field. This instrument will provide for various real time imaging modalities, for physical property measurements and for tissue biopsy and tissue excision. This instrument allows any appropriate medical or non medical system to undergo the appropriate procedure.

12. Referring to claim 11, the system allows for a medical examination of the digestive tract, reproductive tract, trachea, lungs, vascular system or any accessible body cavity.
-
13. Referring to claim 11, the capsule with an external physical connection may have light sources, imaging lenses, power lines, communication lines, injection hoses, suction hoses and other lines and hoses extending from the capsule and connecting to an external control instrument.
-
14. Referring to claim 11, the capsule without an external physical connection may have light sources, imaging lenses, cameras, communications and a power source.
-
15. Referring to claim 11, the capsule with or without an external physical connection may have electronic control, magnetic sensors, the ability to operate under magnetic conditions, mechanical equipment for tissue biopsy and tissue excision or other procedures and the programming of a predetermined movement pattern.
-
16. Referring to claim 11, by holding the capsule stationary with some of the field generating structures, the other field generating structures may be used to manipulate the external magnetic field to operate a small generator (whose motion may be rotary, curvilinear or linear) within the capsule to recharge the power source.
-
17. Referring to claim 11, the instrument allows for real time display of information, virtual three dimensional image of the completed portion of the exam, real time mapping of the capsule'"'"'s trajectory via the gyroscope and accelerometer, marking points of interest and storage of data from all sensors and equipment along the entire trajectory.
-
18. Referring to claim 11, the capsule allows the measurement of temperature, pH, substance concentration, pressure, strain, force, magnetic field, electric field and other physical quantities.
-
19. Referring to claim 11, the capsule allows the detection and production of sound waves, the detection and production of electromagnetic waves, the detection and production of elementary and nuclear particles and the examination by other modalities.
-
20. Referring to claim 11, the externally generated magnetic field for controlling the capsules may be created by:
-
appropriately placing six field generating structures on the six faces of an imaginary cube; have current running through each of the six field generating structures which effectively allows a pair of field generating structures to control each spatial dimension; placing the patient undergoing the medical examination inside the imaginary cube; moving the capsule by appropriately changing the field generating structure current and position and the patient'"'"'s position.
