    摘要： A guide wire includes an elongated main body possessing flexibility. The main boy is comprised of a first wire having a core member constituted by a metal material, a second wire having a core member arranged on the proximal side of the first wire and constituted by a metal material, and an optically transmissive member arranged between the first wire and the second wire, and connecting the first and second wires to each other and constituted by a substantially transparent tube shaped body. The optically transmissive member exhibits light permeability such that when light is illuminated from one direction of a lateral side thereof, the light is transmissible to the opposite side through the center axis of the main body.

    摘要： A flexible tube includes a helical tube having a first sparsely wound region, a closely wound region, a change region, and a second sparsely wound region. In a state where the change region is arranged between the closely wound region and the second sparsely wound region, the change region changes an unbendability such that the unbendability of the distal end portion of the third flexible portion is closer to the unbendability of the second flexible portion and the unbendability of the proximal end portion of the third flexible portion is closer to the unbendability of the fourth flexible portion.

    摘要： A medical device includes a sheath having a guide wire lumen allowing a guide wire to be inserted therein and an imaging core lumen configured to have an ultrasound transducer inserted therein that acquires image information inside a living body. The medical device includes a rotary shaft that is inserted into the imaging core lumen and is rotatable in order to transmit mechanical drive force to the ultrasound transducer. In the sheath, a circular portion having a constant radii of curvature of the imaging core lumen is formed on a side separated from the guide wire lumen, and a non-circular portion having distances from the center point of the circular portion to the inner surface of the imaging core lumen non-uniform and longer than the radius of the circular portion is formed in at least a part of a side close to the guide wire lumen.

    摘要： A controller operates in different operating modes to control movement of a distal tip of a medical instrument when inserting and retracting the medical instrument through linked body passages. When inserting the medical instrument, the controller normally operates in an automatic navigation mode unless manually overridden to operate in a manual mode. When retracting the medical instrument, the controller normally operates in a zero-force mode to allow the distal tip to freely move so that it may comply with the shape of the passages as the medical instrument is being retracted through the linked body unless manually overridden to operate in a manual mode.

    摘要： A video endoscope comprises a shaft comprising a rigid, proximal-side section and a distal section that is laterally deflectable in a plane from the central longitudinal axis of the shaft. A housing is arranged at the proximal end of the shaft. A control element for controlling the deflection of the shaft is provided at the housing. A rod-like pull element extends in the shaft in an off-center fashion with respect to the central longitudinal axis. The pull element is coupled with the control element and with a distal end of the deflectable section of the shaft, wherein a movement of the pull element by the control element in the proximal direction effects a lateral deflection of the deflectable section. A push tube is provided that is arranged to encase the exterior side of the pull element. The push tube extends from the proximal connection of the pull element with the control element through the first opening into the shaft.
