Description
本出願は、Lee Bolduc氏らにより2015年1月21日に出願された米国仮特許出願第62/105,800、「操作機構を持つガイドカテーテル」の権利を主張するものであり、参照によりその全体を本明細書に包含する。
Claims (8)
- 血管内ガイドカテーテルであって、
引きワイヤの動作を介して屈折するよう構成された遠位端部を有する可撓ガイドチューブと、
前記ガイドチューブに連結され、操作組立体を備えるハンドルと、を備え、
前記操作組立体は、前記ガイドチューブの前記遠位端部を屈曲するために前記引きワイヤを動作するよう構成され、
前記血管内ガイドカテーテルは、
固定ラックと、
ラックを係合するギアと、
前記ギアに連結し、共に回転するよう構成されたリールと、を備え、
前記引きワイヤは前記リールの回転によって前記引きワイヤが前記リールに巻き付くかまたはほどかれるように前記リールに連結され、
前記血管内ガイドカテーテルは、
前記ラックに対して移動するのに適したスライダーを備え、
前記スライダーの移動が前記ラックに対して前記リールを移動し、前記ラックに沿った前記ギアの回転が前記リールを回転させ、
前記操作組立体が、前記ハンドルの遠位端に配置されたアクチュエータを含み、前記アクチュエータが、前記ラックに対して前記スライダーの移動を行うよう前記ガイドカテーテルの縦軸の周りを回転するよう構成され、前記アクチュエータが、ネジ式ロッドの周囲に外部から配置され、かつ前記ネジ式ロッドに連結され、
前記ネジ式ロッドが、並進運動のために構成され、かつ近位端部で前記スライダーに連結する、前記血管内ガイドカテーテル。 - 前記ギアが前記スライダーに連結し、かつ前記スライダーの移動が前記ギアを前記ラックに沿って移動させ、かつ回転させる、請求項1に記載の前記ガイドカテーテル。
- 前記リールが、前記ギアと一体となっており、それにより前記リールがさらなる中間構成要素なしに前記ギアに直接連結する、請求項1に記載の前記ガイドカテーテル。
- 前記ギアが、ピンのみを介して前記スライダーに直接連結される、請求項1に記載の前記ガイドカテーテル。
- 前記ギアが、前記スライダーの運動を前記リールを回転させる回転へと変換するために前記ラックと係合する、請求項1に記載の前記ガイドカテーテル。
- 前記ギア及び前記ラックが戻り止めし、それによりユーザーが作動しなければ前記リールが前記引きワイヤを巻き付けまたはほどくことができない、請求項1に記載の前記ガイドカテーテル。
- 前記引きワイヤの移動距離が、前記スライダーの線形移動と前記リールの回転による巻き付きまたはほどき量の組み合わせを含む、請求項1に記載の前記ガイドカテーテル。
- 組織に1つ以上の固定具を適用するよう構成された操作ツールと組み合わせる、請求項1に記載の前記ガイドカテーテルを含むシステム。
