Abstract
The medical catheter tube of the present invention integrally has an inner layer tube; reinforcement material layers formed by placing element wires on the inner layer tube; a marker; and an outer layer tube. The element wires, which are first and the other element wires, for forming the reinforcement material layers are synthetic resin element wires and/or metallic element wires, the first element wires are placed in the axis direction of the catheter to form the first reinforcement material layer, and the other element wires are wound in a coil form on the first reinforcement material layer, in the circumferential direction of the catheter, to cover the first reinforcement material layer. The marker is flexible to deformation. Because of the presence of the reinforcement material layer and the outer layer tube, flexural rigidity from a base section to a head section is reduced in a stepped or continuous manner.
