CATHETER AND METHOD FOR ENGAGING CATHETER

[Problem] Provided is a catheter excellent in operability and a method for catheter engagement.[Solution] A catheter (1) for a hepatic artery to be introduced from an arm of a patient includes a tubular body (2). The tubular body (2) includes an inner layer (31), an outer layer (32), and a reinforcement body (33) embedded in the tubular body (2). The tubular body (2) includes a substantially linear main body portion (23) and a shaped portion (24) shaped in a manner of being bent on substantially the same plane. The shaped portion (24) includes a first bent portion (25) defining a first angle (θ4) distal of the main body portion (23), a second bent portion (26) defining a second angle (θ5) distal of the first bent portion (25) and bent to the same side as the first bent portion (25), a third bent portion (27) defining a third angle (θ3) distal of the second bent portion (26) and bent to a side opposite to the second bent portion (26), and a most distal portion (28) disposed distal of the third bent portion (27). A physical property changing point is provided between a proximal portion (25A) of the first bent portion (25) and a distal portion (26A) of the second bent portion (26).
