Summary:To provide a catheter.SOLUTION: A multi-electrode catheter is presented herein having a puller wire including a distal end bonded to a coupler tube between a catheter shaft body and an end effector. Because the puller wire is bonded to the coupler tube, a distal portion of the catheter body shaft, at least up to a proximal end of the coupler tube, can be deflected when the puller wire is retracted. The coupler tube may also be flexible and be deflectable when the puller wire is retracted. The coupler tube may bend with a radius of curvature that is greater than, equal to, or less than a radius of curvature of the distal portion of the catheter body shaft, depending on design considerations of the catheter. The coupler tube may be made of a flexible material and/or may include sidewall slits which facilitate bending of the coupler tube.SELECTED DRAWING: Figure 1 【課題】カテーテルを提供すること。【解決手段】カテーテルシャフト本体とエンドエフェクタとの間のカプラ管に接着された遠位端を含む牽引ワイヤを有する多電極カテーテルが、本明細書で提示されている。牽引ワイヤがカプラ管に接着されているため、少なくともカプラ管の近位端までの、カテーテル本体シャフトの遠位部分は、牽引ワイヤが後退させられるときに偏向され得る。カプラ管もまた、可撓性であり得、牽引ワイヤが後退させられるときに偏向可能であり得る。カプラ管は、カテーテルの設計上の考慮事項に応じて、カテーテル本体シャフトの遠位部分の曲率半径よりも大きい、等しい、又は小さい曲率半径で曲がることができる。カプラ管は、可撓性材料から作製され得、及び／又はカプラ管の曲がりを容易にする側壁スリットを含み得る。【選択図】図１
