A process for arranging a protective sheath on a drug-coated balloon catheter, the protective sheath having a wall circling in a peripheral direction, this wall surrounding an interior of the protective sheath, the process having at least the following step: - Arranging the protective sheath on a drug-coated area of the balloon catheter by machine production of a relative motion between the balloon catheter and the protective sheath, wherein - the drug-coated area of the balloon catheter is protected, by at least one first and one second flexible film (5, 6), against coming in contact with a guide for the balloon catheter during the relative motion, or - the balloon catheter is held away from the drug-coated area during the relative motion, wherein the relative motion is produced with the help of a first and a second contact element (60, 61), the two contact elements (60, 61) being movable out of a first position toward one another into a second position, and after the balloon catheter is inserted into the interior of the protective sheath, the two contact elements (60, 61) are moved into the second position, so that the two contact elements (60, 61) reach behind one end of the protective sheath or grip a section of the protective sheath, the balloon catheter being held by means of a holding device, and the two contact elements (60, 61) being moved along the balloon catheter, carrying along the protective sheath, the protective sheath being pushed over the drug-coated area. - Arranging the protective sheath on a drug-coated area of the balloon catheter by machine production of a relative motion between the balloon catheter and the protective sheath, wherein - the drug-coated area of the balloon catheter is protected, by at least one first and one second flexible film (5, 6), against coming in contact with a guide for the balloon catheter during the relative motion, or - the balloon catheter is held away from the drug-coated area during the relative motion, wherein the relative motion is produced with the help of a first and a second contact element (60, 61), the two contact elements (60, 61) being movable out of a first position toward one another into a second position, and after the balloon catheter is inserted into the interior of the protective sheath, the two contact elements (60, 61) are moved into the second position, so that the two contact elements (60, 61) reach behind one end of the protective sheath or grip a section of the protective sheath, the balloon catheter being held by means of a holding device, and the two contact elements (60, 61) being moved along the balloon catheter, carrying along the protective sheath, the protective sheath being pushed over the drug-coated area. - the drug-coated area of the balloon catheter is protected, by at least one first and one second flexible film (5, 6), against coming in contact with a guide for the balloon catheter during the relative motion, or - the balloon catheter is held away from the drug-coated area during the relative motion, wherein the relative motion is produced with the help of a first and a second contact element (60, 61), the two contact elements (60, 61) being movable out of a first position toward one another into a second position, and after the balloon catheter is inserted into the interior of the protective sheath, the two contact elements (60, 61) are moved into the second position, so that the two contact elements (60, 61) reach behind one end of the protective sheath or grip a section of the protective sheath, the balloon catheter being held by means of a holding device, and the two contact elements (60, 61) being moved along the balloon catheter, carrying along the protective sheath, the protective sheath being pushed over the drug-coated area.
