摘要： An image processing device includes a drive unit connected with an ultrasound element or an image sensor element, and an image processing unit that sequentially generates two-dimensional images of an organ, a blood vessel, or a medical instrument, based on information which is acquired by the ultrasound element or the image sensor element, and that generates a three-dimensional image based on the two-dimensional image. The image processing unit includes a storage unit that stores position correspondence information and/or image correspondence information, and a control unit that determines a position inside the three-dimensional image corresponding to a current position of the ultrasound element or the image sensor element, based on the position correspondence information or the image correspondence information, and that generates display information in real time, in which the determined position inside the three-dimensional image is identified and displayed inside the three-dimensional image.

摘要： An imaging device capable of acquiring images of an internal structure of a living body highly accurately in a wide range. An imaging device has a first housing to which a proximal portion of an outer sheath is fixed, with a drive shaft for driving a imaging unit and an inner sheath extending through the first housing, and a second housing to which a proximal portion of the inner sheath is fixed and which holds the drive shaft rotatably therein. The first housing has a first port held in fluid communication with an inner lumen of the outer sheath, and the second housing is movable toward and away from the first housing. The imaging device also includes a first gap between the inner sheath and the outer sheath and a second gap between the inner sheath and the drive shaft.

摘要： A treatment device is disclosed for treatment of a living body lumen. The treatment device can include an optical fiber having an emitting part that emits laser light from a side circumferential surface. Two or more grooves are provided in the emitting part at places different in a longitudinal direction of the emitting part. The two or more grooves have two or more kinds of shapes and intensities of the laser light emitted from the grooves adjacent to each other are different. A maximum region of intensity of the laser light emitted from the emitting part is located on one end side relative to a center position in the longitudinal direction of the emitting part. The intensity of the laser light emitted from the emitting part on the other end side of the emitting part relative to a position of the maximum region decreases toward the other end side.

摘要： A laser light irradiation device is disclosed, which can include an optical guide having a columnar portion and transmitting laser light through the columnar portion; a reflecting portion having a reflecting surface that reflects the laser light transmitted through the optical guide; and a transmitting portion having a window part and disposed between the columnar portion of the optical guide and the reflecting portion in such a manner that one end of the transmitting portion is in contact with the columnar portion, the transmitting portion transmitting the laser light emitted from the columnar portion to the reflecting portion and transmitting the laser light reflected by the reflecting surface to cause the laser light to be radiated to an external through the window part. A diameter of the reflecting surface gradually becomes smaller as distance from a boundary between the transmitting portion and the reflecting portion increases.
