Abstract
A medical tube characterized in that it dilates at its cut ends toward the external surface when it is cut at any random portion transversely relative to its longitudinal direction. The patency of the sutured portion may be maintained in good condition over a long time, since pannus formation in the internal cavity can be obviated at the sutured portion between an organ of a living body and an artificial medical tube.
