Abstract
Catheter tube 2 has a multiple of small bead-like projections 21 formed on the inner surface. The inner surface of the tube 2 comprises projections 21 and flat areas 22. A guide wire inserted into the lumen 5 of the tube 2 contacts its inner surface only at the projections 21. The catheter tube 2 has the inner surface embossed in such a way that the guide wire can be manipulated with high efficiency even if the diameter of the tube is very small.
