Abstract
A catheter including a balloon. The balloon has an elastic inner layer and an elastic outer layer. The inner and outer layers are tubular and are inflatable and deflatable in response to a change of internal pressure of the balloon. The catheter includes a tubular reinforcement member positioned radially between the inner layer and the outer layer. The reinforcement member has a first end portion and a second end portion opposite the first end portion in the axial direction of the catheter. The reinforcement member has an intermediate portion between the first end portion and the second end portion in the axial direction. At least one of the first and second end portions is not directly fixed to both the inner layer and the outer layer. The intermediate portion is not directly fixed to both the inner layer and the outer layer.
