A process for arranging a protective sheath on a drug-coated balloon catheter , the protective sheath having a wall circling in a peripheral direction (U), 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 , 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 , the two contact elements 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 are moved into the second position, so that the two contact elements 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 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 , 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 , the two contact elements 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 are moved into the second position, so that the two contact elements 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 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 , 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 , the two contact elements 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 are moved into the second position, so that the two contact elements 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 being moved along the balloon catheter , carrying along the protective sheath , the protective sheath being pushed over the drug-coated area . <EOS>
