SUBSTANCE: catheter has end part provided with one or several draining or discharge holes adjacent to free end which is designed for introduction into the openings of body and external surface of catheter is coated. Method includes the following phases: injection molding of separate end part of catheter. The end part has internal lumen and the drainage/discharge holes. Inner and outer diameters of the end part correspond to respective diameters of standard tube. End of standard tube and end of the end part are formed and matched with each other for subsequent connection of the end part with standard tubes which is coated before connection. The invention also covers catheter made by the claimed method. EFFECT: provided accurate sizes of break-through openings due to ensured the same thickness of walls with coating and prevented bending of catheter with coating. 14 cl |
