Zusammenfassung:	A catheter is provided whose distal end can be introduced through an artery in the arm into the entrance of the left coronary artery. The catheter includes a catheter body (11) having an outer diameter of at most 2.7 mm over its entire length and has a proximal segment (12) straight under a free state and a distal segment (13) having a curved shape under a free state. The distal segment (13) includes a first straight portion (132) contiguous to the proximal segment (12) through a first curved portion (131), a second straight portion (134) contiguous to the first straight portion (132) through a second curved portion (133) bent in a direction opposite to the bending direction of the first curved portion (131), a third straight portion (136) contiguous to the second straight portion (134) through a third curved portion (135) bent in the bending direction of the second curved portion (133), and a straight distal end portion (138) contiguous to the third straight portion (136) through a fourth curved portion (137) bent in the bending direction of the third curved portion (135).
