A deflectable catheter having an outer member having a proximal portion and a distal portion, an elongated columnar member extending from the outer member to the distal side, and an inner member mounted coaxially with the outer member and attached to the columnar member Features a deflectable catheter. The inner member extends to the distal side of the outer member and the inner member has a distal end portion. The stiffening member is disposed in a cylindrical member so as to limit the axial movement of the columnar member, and when one of the inner member or the outer member is moved relative to the other side, the axial compression of the columnar member is restricted by the reinforcement member and the distal end of the inner member The tip portion is deflected sideways.偏向可能なカテーテルであって、近位部分及び遠位部分を備えた外側部材と、外側部材から遠位側に延びる細長い柱状部材と、外側部材と同軸に位置決めされると共に柱状部材に取り付けられた内側部材とを有することを特徴とする偏向可能カテーテル。内側部材は、外側部材の遠位側に延び、内側部材は、遠位先端部分を有する。補強部材が柱状部材の軸方向運動を制限するよう柱状部材に嵌めた状態で配置され、内側部材又は外側部材のうちの一方が他方に対して動かされると、柱状部材の軸方向圧縮が補強部材によって制限され、内側部材の遠位先端部分が側方に偏向するようになっている。
