Abstract
Abstract A medical tube for use for inspection, diagnosis, and treatment of a lesion occurring in a vessel. The shape of the cross section of this medical tube is flat (e.g. an oval). A medical tube having a flat shape is firm and hence has a great strength, and is superior in flexibility. Moreover, since it easily bends only in a direction of its short axis, an operation made locally by an operator can accurately be transmitted to the distal end portion. It is possible to form a plurality of interior holes in the medical tube, in which case these interior holes are arranged on the long axis of the tube.
