Indwelling apparatus for body cavity introducing device and body cavity introducing device placing system

Provided is a capsule medical apparatus including a capsule body, a control member, and an observing member. The capsule body is to be introduced into a lumen of a subject. The control member controls a movement of the capsule body in the lumen by a flow of a fluid introduced in the lumen. The observing member is fixed inside the capsule body and observes a direction of the flow of the fluid and a direction different from the flow of the fluid according to the movement of the capsule body.

Capsule medical apparatus with projections and body-cavity observation method

An encapsulated endoscope system in accordance with the present invention comprises: an encapsulated endoscope that rotates to develop a thrust; a controller that moves the encapsulated endoscope in an intended direction of advancement; an imaging unit incorporated in the encapsulated endoscope; and an image processing unit that receives image data sent from the imaging unit, and produces an image, which results from rotation of the received image data, according to the rotational phase of the encapsulated endoscope.

Encapsulated endoscope system in which endoscope moves in lumen by itself and rotation of image of region to be observed is ceased

Using a guidance system with a simple configuration, propulsive motion along a longitudinal direction and changing of the propulsion direction are easily performed with good precision and stability. There is provided a capsule-type medical apparatus which is inserted into the body of a subject and is guided by an external magnetic field, the capsule-type medical apparatus comprising: a substantially cylindrical capsule; a propulsion mechanism for converting rotary motion about a longitudinal axis R of the capsule into propulsive motion along the longitudinal axis R; a magnet accommodated inside the capsule and disposed in such a manner that the magnetic-pole direction thereof can be switched between a direction along the longitudinal axis R and a direction intersecting the longitudinal axis R; and a securing portion for securing the magnet to the capsule in each of the switched states of the magnetic-pole direction.

Capsule-type medical apparatus, guidance system and guidance method therefor, and intrasubject insertion apparatus

Provided is an intra-subject medical system which includes a body-insertable device and a physical quantity generator. The body-insertable device is to be introduced into a subject, is covered by a capsule-shaped exterior member, and includes a physical quantity detecting member which has a directivity to detect a predetermined physical quantity; at least one functional member which has a necessary function for examining or treating inside the subject; and a switch control unit which controls an on/off state or operation mode of the at least one functional member when the physical quantity detecting member detects a physical quantity. The physical quantity generator has a physical quantity emitting unit which emits a temporary physical quantity inside the subject; and a physical quantity direction changing unit which changes an emission direction of the physical quantity.

Intra-subject medical system, method of operating body-insertable apparatus and operative treatment

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.
