The invention is a medical implant which is a wrap-around cuff comprising a flexible, biocompatible, film carrier substrate, that has a carrier substrate region which is wrapped around a wrap axis to form a tube. The invention has a protective structure directly or indirectly attached to the carrier substrate, which can be transformed from a first, open state into a second closed state that encloses the carrier substrate region that is wrapped to form a tube at least axially around a wrapping axis extending in the peripheral direction of the tube.
