Abstract

PURPOSE:To enable a tube for medical treatment to be easily and accurately inserted into an internal organ so as to prevent the internal organ from being damaged, by providing a partition of the tube longitudinally twisted therein. CONSTITUTION:A lumen tube 1, for example, has a flexible tube member 1a and hollows 2, 2 which are separated by a partition 3 extending straight in the direction of the diameter. The strip of partition 3 is longitudinally twisted in the lumen tube 1 so as to form the hollows 2, 2 spirally. The lumen tube 1 is thus easily bent in every direction, but is constructed not to be easily broken. When a line guide or an image guide consisting of optical fibers is internally provided in the hollows 2, 2, the guide runs alternatively in the inner side and the outer side of the bending. Because of the set up thus arranged, any large stretching or contraction is not generated in the longitudinal direction, thereby preventing the occurrence of kink in the optical fiber.
