摘要： A stent (1) formed into a generally tubular body and expandable radially outward from the 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.
