Abstract: A balloon catheter is characterized by comprising: an expandable balloon (40); a hypotube (31) which extends in the longitudinal direction; tube members (322, 323) which extend in the longitudinal direction, are connected to the proximal end side of the balloon (40) and to the distal end side of the hypotube (31), and are provided on the side surface thereof with a guide wire port (330) through which a guide wire (11) is inserted; an inner tube (324) which has at least a part thereof disposed within the tube members (322, 323) at a position between the balloon (40) and the guide wire port (330) and which has an inner surface having a frictional coefficient lower than that of the tube members (322, 323); and a connection tube (325) which communicates with the inner tube (324), has the proximal side thereof disposed in the vicinity of the guide wire port (330), and has hardness lower than that of the tube members (322, 323).

Abstract: An object of the present invention is to provide a balloon catheter that has excellent pushability upon insertion into a blood vessel, and in which kinking of an outer shaft on the rear end side of a position where a guide wire port is formed can be reliably prevented, and that can be smoothly inserted even into a curved blood vessel. The balloon catheter of the present invention includes an outer shaft (10) composed of a resin tube, a balloon (30), a hub (60), an inner tube (40) and a core wire (50). The rear end side of the straight portion (51) of the core wire (50) is fixed to the inner peripheral surface of the outer shaft (10) on the rear end side of the position where a guide wire port is formed, and the distal end side of the straight portion (51) of the core wire (50) is press-fitted between the inner peripheral surface of the outer shaft (10) and the outer peripheral surface of the inner tube (40).
