Abstract
A process for repositioning a drug-coated stent that is pre-crimped on a balloon of a balloon catheter extending in an axial direction so that an inner surface of the stent lies against an outer surface of the balloon. The stent is gripped with at least one contact element and a protection device between the stent and the at least one contact element to prevent contact between the stent and the at least one contact element. The stent is moved with the at least one contact element in the axial direction with respect to the balloon of the balloon catheter to reposition the stent with respect to the balloon.
