摘要： Catheter of such a structure that Ti—Ni superelastic allow (SEA) tube has its outside covered with thin-film silicone rubber tube. The SEA tube at part whose flexion is desired is wrought to cut off multiple grooves (crenas) with thin joints left. The covering with the silicone rubber tube is effected without the use of its front end portion in the covering. When a negative pressure is applied to physiological saline placed therein, the front end portion works as a valve, and the silicone rubber tube at the wrought part yields inward so that flexion of the catheter occurs at that part.

摘要： A scanning mirror unit for scanning a beam comprises: at least one cantilever which is formed by bonding an elastic material and a piezoelectric material together and supported by a base at its one end; and a movable mirror which is supported at least by a free end of the cantilever at its peripheral part. When voltage is applied to the piezoelectric material, the free end of the cantilever moves in a prescribed direction to press and move the peripheral part of the movable mirror while leaving a central part of the movable mirror at substantially the same position to cause a tilt to the movable mirror. With such composition of the scanning mirror unit, a reflecting member having a sufficient thickness (e.g. some hundreds of microns) can be employed for the movable mirror, by which a high power laser beam effective for treatment of affected parts, etc. can be reflected finely and durably.

摘要： An active tube and its system are offered which can be directed by bending its tip, controlling the degree of bend, thereby easily capable of insertion into difficult positions, and which can be driven at low temperature at which it can be used for inspection and medical treatment. A bending mechanism (21) is constructed by wiring an SMA coil (21e) along an outer side of a working channel tube (21a). The bending mechanism (21) is inserted into an outer skin tube (25) with a plurality of built-in weights (22). A front tip (23) is attached to the front end side of the bending mechanism (21) as a tip (2) of an active tube (1). A main tube (4) is connected through the working channel tube (21a) at the tip (2). A wire (21g) is connected to the SMA coil (21e). Said wire (21g) is inserted to the behind end side (41) of the main tube (4) in a wiring channel (4B9 of the main tube, thereby makes it possible to drive the bending mechanism (21) from outside.
