PROBLEM TO BE SOLVED: To provide a stent which can place in a lumen of a tubiform organ, i.e., the trachea and so forth stably without stimulating a part which is sensitive to stimulation, i.e., a membranous part of a side of the trachea which adjoins to the esophagus too much. SOLUTION: An stent which is inserted so as to secure a lumen of a tubiform organ, i.e., the trachea, the bronchi or the esophagus and so forth and to prevent restenosis has a hollow tube main body 2. Plural circular ribs 5 are provided at an outer periphery of the tube main body toward an axial direction at fixed intervals. A notch 6 is formed at a part of the ribs of a circumferential direction in a row toward an axial direction. |
