  1. 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を有し、
    前記外側部材から遠位側に延びる細長い柱状部材を有し、
    前記外側部材と同軸に位置決めされると共に前記柱状部材に取り付けられた内側部材を有し、前記内側部材は、前記外側部材の遠位側に延び、前記内側部材は、遠位先端部分を有し、
    前記柱状部材の軸方向運動を制限するよう前記柱状部材に嵌めた状態で配置された補強部材を有し、前記内側部材又は前記外側部材のうちの一方が他方に対して動かされると、前記柱状部材の軸方向圧縮が前記補強部材によって制限され、前記内側部材の前記遠位先端部分が側方に偏向するようになっている、偏向可能カテーテル。
