Problem to be solved: to provide a tear canal stent which can prevent reocclusion by granulation.The stent includes a cylindrical body part 3 and a tip part 5 positioned at the tip of the body part 3.The tip region 5 becomes wider in width toward the tip.Since the width of the tip part 5 becomes wider as the tip 5 reaches the tip, the blockage by the granulation can be prevented after the stent is installed.Tip 5 may be located at both ends of the stent or only at one end.The diameter (maximum diameter) of the tip part 5 (when the outer circumference is circular) is 1.05 times to 2 times the diameter of the body part 3 (when the outer circumference is circular), and can be 1.5 to 2 times, and can be 1.6 to 1.9 times, and can be 1.1 or 1.3 times or less, and it is 1.2 times or more or 1.3 times or less Or less.Diagram【課題】肉芽による再閉塞を予防できる涙道ステントを提供する。【解決手段】ステントは、筒状の本体部3と,本体部3の先端に位置する先端部位5とを含む。先端部位5は,先端に向かうほど,幅が広くなる。先端部位5が先端に向かうほど幅が広くなるので,ステントを設置した後に肉芽による閉塞を防止できる。先に進むほど幅が広くなる先端部位5は,ステントの両端にあってもよいし,一方の端部にのみ存在してもよい。先端部位5(の外周を円状にした際)の直径(最大径)は,本体部3(の外周を円状にした際)の直径の1.05倍から2倍があげられ,1.5倍~2倍でもよく,1.6倍~1.9倍でもよく,1.1倍以上1.3倍以下でもよいし,1.2倍以上1.3倍以下でもよい。【選択図】図1
