Abstract
A protective device for an elongate catheter carrying a functional element, in particular a stent or a balloon, in particular a balloon coated with an active substance, on a distal end portion of the catheter. The protective device includes a protector configured to be arranged on the distal end portion so that the functional element is surrounded by the protector. A protective sleeve surrounds an interior to receive the catheter together with the protector. The protective sleeve has at least one projection on an inner side of the protective sleeve facing the interior of the protective sleeve. The projection is configured to retain the protector when the catheter together with the protector is arranged in the interior of the protective sleeve and the catheter is withdrawn from the protective sleeve so that the protector is pulled off the distal end portion of the catheter.
