Description
第1の態様として、ステント送達システム10は、図29a、29b、29dに示されているように、TYPE1(タイプ1)、TYPE2(タイプ2)又はTYPE4(タイプ4)のそれぞれに送達されるように意図されている。これらのタイプの分岐部病変において、プラーク4は、少なくとも部分的に、分岐点3の周辺の主血管の中に位置し、血管枝2の中にもまた位置する。
第2の態様において、ステント送達システム110は、図29e、29fに示されるように、タイプ4A、4Bの分岐部病変に送達されるように意図されている。タイプ4Aの病変は、プラーク4が、分岐点3の近傍の、血管枝2の中に位置している。タイプ4Bの病変では、プラーク4が、主血管1の分岐点3の近位に位置する。そのような配置となる一例としては、冠動脈があり、例えば、冠動脈内にプラークが被覆することで生じる左冠動脈前下行枝(LAD)の閉塞が回避される必要がある。他の例には、腎動脈、左冠動脈主幹部、静脈グラフト等が含まれる。
その他の態様としては、図19に示すように、Y字型の状態を有する分岐部3に送達されるよう意図されたステント送達システム310である。主血管1は、2つの分岐血管;第1血管枝2及び第2血管枝2’、に枝分かれしている。そして、プラーク4が、分岐点3の領域の主血管及び/又は血管枝の中に位置する。
他の態様として、ステント送達システム510は、図29cに示されたTYPE3(タイプ3)の分岐部病変に送達されることを意図している。タイプ3の病変において、プラーク4が、分岐点3の位置の近位の主血管1に位置している。ステント送達システム510は、同様に以下で説明するように、分岐のない血管にも、送達される場合にも適用される。
