A dilating catheter is provided for introducing and inserting an expandable stent. The dilating catheter includes an inflatable balloon, which is applied on a distal section of said catheter and which can be wrapped, if empty, on the section in order to be applied there around a the contracted stent. The outer surface of the balloon is roughened by means of a supply of material or a deformation in order to offer greater interference and grip to the said stent contracted tightly around it.
