Abstract
Description
このような課題を解決するために、クローズドセル構造のステントでありながら高い柔軟性を発揮する技術として、螺旋状のステントが提案されている(例えば、特許文献1参照)。特許文献1のステントは、展開状態において、波線状パターンを有する螺旋状の環状体と、隣り合う環状体を接続するコイル状要素とを備える。
本明細書等において、形状、幾何学的条件、これらの程度を特定する用語、例えば、「平行」、「方向」等の用語については、その用語の厳密な意味に加えて、ほぼ平行とみなせる程度の範囲、概ねその方向とみなせる範囲を含む。
図1は、第1実施形態のステント10の構成を示す側面図である。図2は、図1に示すステント10を仮想的に平面状に展開した展開図である。図3は、図2に示すステント10の部分拡大図である。図4Aは、図1に示すステント10を拡径した状態を示す側面図である。図4Bは、マーカー100を設けたステント10の側面図である。図4Cは、マーカー100の断面図である。図5A~図5Cは、ステント10における第2頂部19の突出方向を説明する図である。
また、ステント10の表面を、ダイヤモンドライクカーボン(DLC,F-DLC)等の炭素系材料により被覆してもよい。
溶接の方法としては、コイル状バネ120とステント10の先端部110とを溶接で溶かし込んで接着固定する方法と、ステント10の先端部110において、コイル状バネ120から突出している領域を溶かして、コイル状バネ120の移動を規制する方法と、が挙げられる。
銀ロウの浸潤の場合、コイル状バネ120をステント10とは異なる材料から形成し、例えば銀ロウ等をコイル状バネ120の上から染み込ませて、コイル状バネ120をステント10の先端部110に固定する。
図6は、拡径したステント10(図4A参照)を略U字形に屈曲させた場合の各部の形状を示す図である。図7は、図6に示すステント10の各領域におけるセル40の状態を仮想的に平面状に展開した場合の模式図である。図7の中段の図は、引っ張り、圧縮のいずれの力も作用していない無負荷状態(図4Aの状態)のセル40を示している。図8は、図6に示す屈曲させたステント10の領域S1における連続したセル40の状態を仮想的に平面状に展開した場合の模式図である。図8では、上段にストラット50の断面を模式的に円で描いている。この円は、一つのストラット50に作用する応力を説明するために描いたものであり、実際のストラットの断面とは異なる。
図9は、比較例1のステント20を仮想的に平面状に展開した展開図である。図10は、図9に示すステント20の部分拡大図である。図11は、屈曲させたステント20の背側の領域における連続したセル40の状態を仮想的に平面状に展開した場合の模式図である。図11は、屈曲させた比較例1のステント20の背側の領域における連続したセル40の状態を仮想的に平面状に展開した場合の模式図である。
図15A~図15Cは、それぞれ比較例1、比較例2及び実施形態の各ステントの開存性を説明する図である。図15A~図15Cは、比較例1、比較例2及び実施形態のそれぞれのステントを同一の径となるまで拡径し、略U字形に屈曲させたときの断面形状を示している。図15A~図15Cの上段は、破線で示す曲がりの中心部分での断面形状を示している。図15A~図15Cの下段は、ステントを略U字形に屈曲させたときの外観を示している。
次に、第2実施形態のステント10Aについて説明する。第2実施形態の説明及び図面において、第1実施形態と同等の部材等には、第1実施形態と同一の符号を付し、重複する説明を省略する。
