Abstract: A capsule casing of a capsule medical device has a chemical sensor inside, used for sensing operation. The chemical sensor has a recovery device which resets the chemical sensor to an initial state thereof so as to use the chemical sensor for the sensing operation a plurality of times or continuously.

Abstract: A lumen passability checking device checks whether a capsule medical device configured to be introduced into a gastrointestinal tract of a subject is allowed to pass through the gastrointestinal tract. The device includes: a main body dissolvable by a substance in the gastrointestinal tract; a first layer coating the main body, having an outer diameter substantially equivalent to an outer diameter in a minor axis of the capsule medical device, and being dissolvable by the substance in the gastrointestinal tract; and a second layer coating the first layer and being dissolvable by the substance in the gastrointestinal tract. The first and second layers contain different discriminating materials. The first layer has at least two regions extending along a circumference of a cross section of the first layer, the cross section intersecting with a long axis of the device, a part of each region being thinner than other parts.

Abstract: A capsule-type medical device comprises a capsule main unit having functions for being inserted into the body cavity and performing medical acts such as taking images or the like. The capsule main unit comprises therein a magnet which is acted upon by external magnetism, and a spiral portion on the outer perimeter, so that rotating force acting upon the magnet is readily converted into a propelling force for propelling the capsule-type medical device. A flexible insertion portion which is long and small in diameter is provided to the capsule main unit to allow smooth progression through the body cavity, and the center of gravity of the device is placed upon the longitudinal center axis of the capsule main unit, thus facilitating smooth progression through the body cavity.
