Abstract: Provided is a filling liquid (161) for filling a balloon (170) for a method for occluding a tubular organ, including a microcapsule (162) in which a balloon-dissolving substance that dissolves the balloon (170) is encapsulated, wherein the microcapsule is destroyable by an ultrasonic beam; and a liquid that is harmless in the tubular organ and does not dissolve the balloon. Further provided is a method for terminating a tubular organ occlusion including a step of applying an ultrasonic beam to a balloon (170) that is filled with the filling liquid (161) and occludes a tubular organ, thereby breaking the balloon (170) as a result.

Abstract: A high-resolution and compact endoscopic apparatus is provided. The endoscopic apparatus comprises: an insertion unit configured to be inserted into a body cavity and guide light from an object; an illumination device attached to the insertion unit and illuminating the object; and an imaging device comprising 8K-level or higher-level pixels arranged in a matrix form. The imaging device receives light reflected from the object and guided through the insertion unit and outputs image data of the object. The pitch of the pixels of the imaging device is equal to or larger than the longest wavelength of illumination light emitted from the illumination means.

Abstract: Provided is an endoscope system wherein, when a trigger signal generating unit of an endoscope (10) generates a zoom-in or zoom-out trigger signal, a control device (40) identifies the fixation point of an operator in a display image of a display device (30) on the basis of a relationship between a detection signal from a sensor in polarized glasses (50) and a detection signal from a sensor in the display device (30) at the time of generation of the trigger signal, and zooms in or zooms out the peripheries of the fixation point.

Abstract: An endoscope device is provided to comprise an insertion unit configured to be inserted into a body cavity and guide light from an object, an illumination device attached to the insertion unit and illuminating the object, and an imaging device having an imaging element provided with 8K-level or higher-level pixels. The imaging element receives light reflected from the object and guided by the insertion unit and outputs imaging signals of the object. The insertion unit and the illumination device may be attached to the imaging device. The imaging device may be grasped and carried by a human hand. The imaging device has a mounting part incorporating the imaging element and a grasping part. The cross-sectional area of the mounting part perpendicular to an optical axis is equal to or larger than the cross-sectional area of the grasping part perpendicular to the optical axis.

Abstract: The object lens 21 and the ocular lens 22 are disposed in the lens barrel unit 11 and the relay lens system 23 is disposed therebetween. The image sensor 31 is disposed in the camera unit 12 and the coaxial illumination unit 32 is disposed therearound. The focus position shift member 25 is disposed at the image formation position L1 in the lens barrel unit 11. The light from the coaxial illumination unit 32 is imaged at the image formation position L1 and is shifted to a position L2 by the focus position shift member 25. Since the position L2 positions at a position closer than a focus position, light through the object lens 21 diffuses to illuminate the object 51.

Abstract: An in-vivo information extracting system comprises a tag device (1) embedded in a living body, a relay device (2) disposed outside the living body and near the tag device (1), and main transceiver (3) for collecting the in-vivo information extracted by the tag device (1) through the relay device (2). The tag device (1) has a rectifier circuit for rectifying an electromagnetic wave received from the relay device (2) and generating an operating power. By thus generating, inside the tag device, the operating power needed to drive the tag device (1) from the electromagnetic wave fed from outside by means of an RFID, any cell or battery in the tag device (1) is not needed, and the size of the tag device (1) is accordingly reduced. Therefore, the tag device can be used in a living body almost permanently.
