<p>A balloon catheter capable of expanding the stenosed part of a blood vessel near a bent portion and capable of forming the shape of a balloon in a specific bent shape without performing delicate control. The balloon (5) of the balloon catheter (1) is molded in a shape having the bent portion beforehand. When the internal pressure of the balloon (5) is increased, the balloon is expanded so as to be formed in the bent shape provided at the time of molding. Since the bent shape is maintained even if the internal pressure of the balloon (5) is increased, the bent angle, diameter, and length of the balloon (5) are not changed according to a rise in the internal pressure of the balloon (5). Thus, the balloon (5) can be expanded to the predetermined bent shape even if the internal pressure of the balloon (5) is not delicately controlled.</p> |
