| 20080281188 | DETECTING SYSTEM OF POSITION AND POSTURE OF CAPSULE MEDICAL DEVICE - A detecting system of the position and the posture of a capsule medical device includes a main body of the capsule medical device that is inserted in a living body, a coil in a capsule that is arranged to the main body of the capsule medical device and forms a resonant circuit, a magnetic field generating device that is arranged around the living body and generates the Alternating magnetic field for generating an induced magnetic field in the coil in the capsule, and a plurality of magnetic field detecting devices that detect the strength of the induced magnetic field generated by the coil in the capsule by the magnetic field generated by the magnetic field generating device. | 11-13-2008 |
| 20080294006 | ENCAPSULATED MEDICAL DEVICE GUIDANCE SYSTEM, AND A METHOD OF CONTROLLING THE SAME - An encapsulated medical device guidance system, and a method of controlling the system, in which a magnetic generator acts on a magnet built into a capsulated medical device, and generates a magnetic field for controlling the position and/or posture of the capsulated medical device, and a control unit has a dynamic torque estimation unit to estimate a dynamic torque to be applied to the encapsulated medical device in a target posture, controls a magnetic field generated from the magnetic field generator so that a magnetic torque generated by the magnetic field generator becomes proportional to a dynamic torque estimated by the dynamic torque estimation unit, and controls the posture of a capsule endoscope by considering gravity applied to the capsule endoscope itself. | 11-27-2008 |
| 20080300453 | INTRA-SUBJECT OBSERVATION SYSTEM AND INTRA-SUBJECT OBSERVATION METHOD - An intra-subject observation system includes a first liquid inserted into a desired organ of a subject; and a second liquid inserted into the organ without being mixed with the first liquid due to a specific gravity lighter than that of the first liquid. The system also includes a capsule medical apparatus inserted into the organ with an intermediate specific gravity between the specific gravity of the first liquid and that of the second liquid to acquire intra-subject information, which is output out of the subject by radio. | 12-04-2008 |
| 20080306340 | ENCAPSULATED MEDICAL DEVICE GUIDANCE SYSTEM, AND METHOD OF CONTROLLING THE SAME - An encapsulated medical device guidance system, and a method of controlling the system, in which guidance coils are arranged to divide a magnetic field generating plane into at least two front and rear areas, a magnetic field for canceling gravity applied to a capsule endoscope itself is formed, and superposed on a magnetic field for moving or changing an attitude, a frictional resistance in moving a capsule endoscope is reduced by decreasing an area of an endoscope to contact the surface of an intracavital. | 12-11-2008 |
