<p>PROBLEM TO BE SOLVED: To provide a stent capable of sufficiently securing high flexibility and radiation supporting force. SOLUTION: In this stent (1, 1A, 1B), a cell (6, 6A, 6B) is provided with at least one flexible part (12, 12A, 12B), approximately linear part (11, 11A, 11B) and approximately linear part (15, 15A, 13B) adjacent to the flexible part (12, 12A, 12B), an angleθafter expansion of the approximately linear part (11, 11A, 11B) and the approximately linear part (15, 15A, 13B) is determined to be 30 deg. or more in expansion of at leastϕ2.5 mm, six to twelve pieces of cells (6, 6A, 6B) are radially arranged when a diameter of the stent (1, 1A, 1B) isϕ3.0 mm or more after the expansion, and three to eight pieces of cells (6, 6A, 6B) are arranged in the axial direction of the stent per 10 mm length of the stent (1, 1A, 1B).</p> |
