Abstract

The canal is used in medical practice and in other activitieswhere the penetration of different instruments is required in amedium vulnerable to the mechanical effect and/or without clearlyformed restricting walls. The canal is made by turning the endsector of a flexible tube where the turned out external partbecomes concentrically fitted around the initial inner tube (1).The outer part acquires the properties of a robust canal (2) andimmediately after the place of the transition it solidifies bycooling of a material (3) in liquid state contained in it, or byvacuumization of hollow canals or canals filled by smallparticles, or by blowing of toroids included in it, or byunfolding of rings made of robust components, or by meshingprofile components included in its walls.11 claims, 10 figures
