Abstract
血管内の所定箇所に留置して血流を遮断するために用いられ、血管内にしっかりと固定されると共に血管を効果的に閉塞可能で、しかも留置に必要な個数も少なくできる血管閉塞具を提供する。
【解決手段】
この血管閉塞具10は、線材11をコイル状に巻いたコイル本体20と、コイル本体20の少なくとも一端にて、コイル本体20の内側又は外側に重ねて配置された重ね巻き部30とからなり、重ね巻き部30は、挿入される血管の内径よりも大きい形状となるよう屈曲形状に付形されている。そのため、重ね巻き部30が挿入される血管の内径よりも大きい形状に形状復帰するので、血流に流されることなくしっかりと固定され、重ね巻き部30以外の部分が血流によって流されても、重ね巻き部30に引っ掛かって密接に絡まるので、血流を効果的に妨げ高い閉塞効果が得られ、必要な個数も少なくできる。
