摘要： A stent (1) formed into a generally or substantially tubular body and expandable radially outward from inside of the tubular body, wherein cells (6) are connected vertically and so arranged as to surround the central axis (C1) of the stent (1) and thereby to form annular units (4), the annular units (4) are extended along the axis of the stent (1), adjacent annular units (4) are connected at least at one portion by a connecting part (5), each of the cells (6) has at least one bent portion, and the angle of the bent portion after expansion of the tubular body until the diameter becomes 2.5 mm is larger than 30°. The stent ensures a high flexibility and radial support force, enhances the blood vessel expandability, and suppresses the foreshortening phenomenon and the flare phenomenon.

摘要： A valve means for changing over concrete material passage is disclosed, wherein a rotational frusto-conical valve body is provided in a hopper. The interior of the valve body is provided with curved circular concrete material intake and discharge passages, the openings of which are alternatingly communicated with openings of double cylinders having pistons therein by rotating the valve body. The other end of the discharge passage is rotatably connected to a pipe to supply the concrete material into the outside of the hopper.
