Abstract

The invention provides a multi-layer membrane comprising a matrix layer predominantly of collagen II and having an open sponge-like texture, and at least one barrier layer having a close, relatively impermeable texture. Such a membrane is particularly suitable for use in guided tissue regeneration, in particular for use in vivo in the reconstruction of bone or cartilage tissue.
