Abstract
Description
第1の例では、ステント送達システムは、遠位先端と近位端との間に延びる細長い内側部材を含む。ステント支持部材は、内側部材の上または周囲に配置され、遠位先端の近位に位置するステント受容領域を含む。内側部材は、ステント支持部材内で摺動可能である。システムはまた、ステント支持部材のステント受容領域を取り囲む少なくとも1つのステントを含む。ステントは、折り畳み態様と拡張態様とを有する。システムはさらに、内側部材の上に摺動可能に配置された細長い外側シースを含む。外側シースは、遠位端と近位端との間に延び、近位部と、近位部の遠位に位置する遠位部とを含む。外側シースの遠位部はステントを囲んで、ステントを折り畳み態様に拘束する。近位接合部は、外側シースの遠位部を外側シースの近位部に取り外し可能に連結する。近位接合部は、外側シースの遠位部を外側シースの近位部から選択的に切り離すように作動可能である。遠位接合部は、外側シースの遠位端を内側部材の遠位先端に取り外し可能に連結する。遠位接合部は、外側シースを遠位先端から選択的に切り離すように作動可能である。遠位および近位接合部は、外側シースの近位部に対して内側部材を回動させることによって別個に作動可能である。
代替的にまたは追加的に、別の例では、第1および第2回動マーカは180度離れて配置される。
代替的または追加的に、別の例では、近位接合部はステントの近位端に隣接する。
代替的にまたは追加的に、別の例では、少なくとも1つのステントは、第1ステントおよび第2ステントを含み、第1および第2ステントは、第2ステントの遠位に配置された第1ステントを用いて、ステント支持部材のステント受容領域を取り囲んでいる。
代替的にまたは追加的に、別の例では、外側シースの遠位部は、近位接合部または遠位接合部が切り離されたときに軸方向長さが短くなるように構成された、少なくとも1つの軸方向折り畳み可能セクションを含む。
