Abstract: A device for supporting a flexible, biocompatible membrane of the type which is arranged between the soft tissue and the bone tissue of a human or an animal so that a space is formed between the membrane and the bone tissue for the purpose of establishing bone growth in this space comprises a central annular part for connection to an implant which is anchored in the bone tissue, and a peripheral part which is intended to extend outwardly form the central part over the space in which bone growth is sought and to form a support for the flexible membrane. The peripheral part consists of one or more wire loops, the wire being made of a biocompatible material, preferably titanium, and being easily bendable by hand and shortened if necessary upon application, while being sufficiently stiff to maintain its shape after bending.
