STENT TO BE IMPLANTED IN ORGANISM

摘要

PROBLEM TO BE SOLVED: To provide a stent having a sufficient expansion force and uniform expansion force as a whole.SOLUTION: A stent 1 to be implanted in an organism is a stent provided with a plurality of wavy annular bodies 2 in the axial direction. The wavy annular body 2 has a plurality of one end side bent parts having an apex 2a on one end side of the stent 1 in the axial direction, and a plurality of other end side bent parts having an apex 2b on the other end side of the stent 1 in the axial direction. The wavy annular body 2 disposed adjacently to each other on the proximal end side in the axial direction of the stent 1 has a sharing linear part 21 having a start end 22 at the apex 2b of one of the other end side bent parts or in a vicinity of the apex 2b in the wavy annular body 2 on the one end side in the axial direction of the stent 1, and a terminal end 23 between the apex 2b of the other end bent part and the apex 2a of the one end side bent part. The sharing linear part 21 integrates the adjacent wavy annular bodies.
