Description
上記の例のいずれかに対して代替的または追加的に、別の例では、近位ストッパは、近位リリースワイヤの外径よりも大きい外径を有してもよい。
上記の例のいずれかに対して代替的または追加的に、別の例では、遠位リリースワイヤの近位端は、近位リリースワイヤの周りに配置されたらせんコイルに形成されてもよい。
上記の例のいずれかに対して代替的または追加的に、別の例では、遠位ストッパは、近位リリースワイヤの遠位端から形成されたループであってもよい。
上記の例のいずれかに対して代替的または追加的に、別の例では、遠位リリースワイヤの近位端は、ループの管腔の直径よりも大きい外寸を有する三次元形状であってもよい。
上記の例のいずれかに対して代替的または追加的に、別の例では、近位リリースワイヤは、所定の軸方向距離にわたって遠位リリースワイヤとは独立して、細長いシャフトの長手方向軸線に沿って近位に移動するように構成されてもよい。
上記の例のいずれかに対して代替的または追加的に、別の例では、遠位ストッパの近位端は、第一の距離よりも長い距離での近位リリースワイヤの近位作動時に、遠位リリースワイヤのらせんコイルの内面または遠位端と係合するように構成されてもよい。
別の例では、医療デバイスシステムは、細長いシャフトであって、細長いシャフトの近位端から細長いシャフトの遠位端まで延びる管腔を有する細長いシャフトと、身体の外側に留まるように構成された近位端から遠位端まで遠位に延びるとともに、細長いシャフトの管腔内に摺動可能に配置された近位リリースワイヤと、近位リリースワイヤの遠位端に結合された遠位ストッパと、遠位ストッパの近位にある近位リリースワイヤに結合された近位ストッパと、近位端から概して線形の遠位端まで遠位に延びるとともに、細長いシャフトの管腔内に摺動可能に配置された遠位リリースワイヤであって、遠位リリースワイヤの近位端は、近位リリースワイヤの線形部分の上に摺動可能に結合された複数の巻線を含む、遠位リリースワイヤと、を備えてもよい。遠位リリースワイヤは、細長いシャフトの遠位端に医療デバイスを解放可能に取り付けるように構成されてもよい。第一の距離にわたる近位リリースワイヤの近位移動は、遠位リリースワイヤとは独立して近位リリースワイヤを移動させてもよく、第一の距離よりも長い第二の距離にわたる近位リリースワイヤの近位移動は、近位リリースワイヤと協調して遠位リリースワイヤを移動させるように構成されてもよい。
上記の例のいずれかに対して代替的または追加的に、別の例では、遠位ストッパは、複数の巻線の内径よりも大きい外径を有してもよい。
本明細書では、明示的に示されているか否かにかかわらず、すべての数値は「約」という用語で修飾されているものとみなす。数値の文脈において、「約」という用語は一般に、当業者が記載された値と同等である(例えば、同じ機能または結果を有する)とみなす数値の範囲を指す。多くの場合、「約」という用語には、最も近い有効数字に丸められた数値が含まれ得る。「約」という用語の他の(例えば、数値以外の文脈での)使用法は、特に明記しない限り、本明細書の文脈から理解され、本明細書の文脈に一貫するように、通常の慣習的な定義を有するものとみなされ得る。
