Abstract: An illumination device for a microscope includes: a lamp house configured to emit illumination light; and a turret having a first mirror unit for polarization observation and a second mirror unit for another observation method, the turret being configured to rotate the first and second mirror units on a plane perpendicular to an optical axis of an observation optical system of the microscope to position one of the first and second mirror units on the optical axis. The first mirror unit includes a polarizer and a mirror. The turret includes an analyzer arranged on an optical axis of the first mirror unit. The turret rotates the analyzer and the first mirror unit on the plane perpendicular to the optical axis of the observation optical system of the microscope while maintaining a positional relation between the analyzer and the first mirror unit.

Abstract: A stent includes a first tubular unit that has a cylindrical tubular shape and a mesh circumferential surface; and a second tubular unit that has a cylindrical tubular shape and a mesh circumferential surface, and is connected to the first tubular unit in a longitudinal axis direction of the stent. The first tubular unit has a first-first direction bent portion which is bent to be convex toward the first direction side that is one side of the longitudinal axis direction, the second tubular unit has a second-second direction bent portion which is bent to be convex toward the second direction side that is the other side of the longitudinal axis direction, and the first-first direction bent portion and the second-second direction bent portion form a first connecting portion that is connected so as to be relatively movable.

Abstract: A stent formed by weaving wires includes: a plurality of straight-line crossing portions, which are formed by crossing at least two straight-line portions of the wires and are arranged adjacent to each other in a circumferential direction of the stent; and a plurality of interlocking portions configured by intersecting a peak-shaped bent portion, in which the wire is bent in a first direction side which is one side of a longitudinal axis direction of the stent and becomes convex, and a valley-shaped bent portion, in which the wire is bent in a second direction side which is the other side of the longitudinal axis direction and becomes convex, and arranged so as to be adjacent to each other in the circumferential direction of the stent, wherein the interlocking portions and the straight-line crossing portions are arranged alternately in the longitudinal axis direction.
