Abstract
A catheter that includes a balloon. The balloon has an elastic inner layer and an elastic outer layer. The inner layer and the outer layer are inflatable and deflatable in response to a change of internal pressure of the balloon. The catheter includes a tubular reinforcement member positioned between the inner layer and the outer layer of the balloon in the radial direction of the balloon. At least part of the reinforcement member is not directly fixed to the inner and outer layers. The reinforcement member includes a wire-shaped member. The first end portion and the second end portion of the reinforcement member include ring-shaped inflation restrictors fused to the wire-shaped member. The inflation restrictors restrict inflation of the first and second end portions of the reinforcement member in the radial direction when the inner and outer layers inflate.
