Abstract
A process for arranging a stent, especially a drug-coated stent, on a balloon of a balloon catheter. At a stent implantation site (e.g., during an angioplasty procedure), the balloon of the balloon catheter serves to expand the stent radially, so that the stent, e.g., opens a vascular stenosis and is securely fixed to the vessel wall. Pressure plates are arranged and operate to maintain a protection device that avoids contamination of the stent.
