<P>PROBLEM TO BE SOLVED: To realize an encapsulated medical device that can smoothly reach a target region in a lumen line without wasteful motion such as eccentric motion. <P>SOLUTION: The encapsulated medical device 1 constitutes a medical system wherein it transmits and receives a radio wave to and from a controller during passage in a body cavity line of a patient and control from the controller can provide inspection, treatment or procedure. The encapsulated medical device 1 together with a magnetic induction device constitutes the medical system. The encapsulated medical device 1 comprises a magnet 36 magnetically actuated by a rotating magnetic field formed by the magnetic induction device, and a helical part 37 as a thrust generating part for converting rotary motion by the magnet 36 into thrust. The center of gravity of a capsule body 1A is substantially aligned with a longitudinal center axis 38. <P>COPYRIGHT: (C)2003,JPO |
