A catheter tube comprises a plurality of longitudinal protrusions extending from the first end of the catheter tube M through at least a portion of the catheter tube, and forming an angle of 0 degrees to 45 degrees with respect to the longitudinal axis of the catheter tube and facing radially inwards, and means for dilating a circumference of the catheter tube upon everting the catheter 01 tube inside-out from the first end of the catheter tube. The longitudinal protrusions ensure the axial reinforcement of the catheter tube, 7r which prevents the tube from collapsing and bending under the axial force and the resistance of the fold and of the friction between © the everted portion and the corresponding underlying portion of the tube. The dilating means dilate the circumference of the catheter GC tube in the everted region, thus reducing the resistance of the fold and of the friction between the everted portion and the corresponding 1-1 underlying portion of the tube.
