PROBLEM TO BE SOLVED: To provide a medical catheter allowing better control of a flexural state of the remote side of the medical catheter inside an organic lumen by reducing the diameter on the remote side of the medical catheter.SOLUTION: This medical catheter includes: a shaft part having flexibility an operation part disposed on the near side of the shaft part an operation wire disposed in a luminal part communicating over the remote side from the near side of the shaft part, and connected to the operation part and the remote side of the shaft part and a tubular wire engagement member having a hollow part fixed to the inner wall face forming the luminal part on the remote side of the shaft part. The remote side of the operation wire is inserted through the hollow part of the wire engagement member, and is joined or locked, and fixed to the wire engagement member or the inner wall face of the remote side rather than the engagement member of the shaft part.COPYRIGHT: (C)2013,JPO&INPIT【課題】医療用カテーテルの遠位側が細径で、生体管腔内での医療用カテーテルの遠位側の曲げ状態をより良く制御可能な医療用カテーテルを提供すること。【解決手段】可撓性を有するシャフト部と、該シャフト部の近位側に配された操作部と、前記シャフト部の近位側から遠位側に亘り連通する内腔部に配され、前記操作部と前記シャフト部の遠位側とに連結される操作ワイヤーと、前記シャフト部の遠位側において前記内腔部を形成する内壁面に固定された中空部を有する筒状のワイヤー係合部材とを備え、前記操作ワイヤーの遠位側は、前記ワイヤー係合部材の中空部内に挿通され、前記シャフト部の前記係合部材よりも遠位側の内壁面に、または、前記ワイヤー係合部材に、接合または係止して固定されることを特徴とする医療用カテーテル。【選択図】図1
