- 偏向機構は、異なる長さの複数の平らな隣り合わせの金属セグメント、および張った状態で位置付けられる際に、複数の平らな隣り合わせの金属セグメントで弯曲を引き起こすように構成された短縮ケーブル、を含む、請求項1に記載の機器。
- 前記偏向機構は、シャフト内で円周方向に回転するようにさらに構成される、請求項1に記載の機器。
- 前記偏向機構は、向かい合って配置された、異なる長さの複数の平らな金属セグメント、および
張った状態で位置付けられる際に、当該複数の平らな金属セグメントで弯曲を引き起こすように構成された短縮ケーブルを含み、
ここで、前記複数の平らな金属セグメントの第1の金属セグメントは前記複数の平らな金属セグメントの最大の長さを有し、前記短縮ケーブルの遠位端は前記第1の金属セグメントに取り付けられ、
