Description
システムは、内側部材と外側部材との間において、相対的な長手方向の移動が比較的わずかであるように設計することができる。
展開に先立ち、外側部材の先端を、展開前の内部人工器官に十分に近接させることが可能であり、その結果、展開時に、中間部材を後退させる際に、内部人工器官が外側部材の直径を超える直径まで拡張することが可能である。
メンブレンは、コーティング(例えば、治療剤を含むコーティング)を有するステント、ステント・グラフト、グラフトなどを、送達時の摩擦によってコーティングをほとんど損なうことなく展開することが可能である。
種々の図の中で同様の参照符号は、同様の要素を示す。
例えば、外側部材は、補強材(例えば内側部材および/または中間部材より剛性であり得る)であり得る。
いくつかの実施形態において、基端から先端にかけてポリマー・デュロメータを変更することによって、1つまたは複数のカテーテル部材の剛性を変えることも可能である。
いくつかの実施形態において、1つまたは複数のカテーテル部材および/またはメンブレンは、少なくとも部分的に透明なポリマーで構築される。このような透明なポリマーを使用して、例えば、部材に実質的に透明な先端領域を提供することができ、この領域によりシースの下の抑止された状態の内部人工器官を確認することが可能になる。
他の実施形態は特許請求の範囲内にある。
