<p><P>PROBLEM TO BE SOLVED: To provide an indwelling stent which has a higher followability to a biological organ and high expandability. <P>SOLUTION: The stent 1 can be expanded, when force which radially spreads from the inside is added, and has connection portions 5 for arranging a plurality of rows of annular units 4 consisting of a plurality of annular linear bodies 2 and a connection portion 3, in the axial direction of the stent. The central opening 20 of the annular linear body 2 has a polygonal shape. The annular linear body 2 has: first tops 21 and second tops 22 which are formed at one end side part of the stent 1 and point to the one end side thereof; third tops 23 which are located between the first top and the second top and points to the other end side of the stent 1; fourth tops 24 and fifth tops 25 which are formed at the other end side part of the stent 1 of the annular linear body 2 and point to the other end side thereof; and sixth tops 26 which are located between the fourth top and the fifth top and points to the one end side of the stent 1. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
