Abstract
The present invention is directed to a biocompatible and preferably biodegradable gradient layer system comprising at least one set of layers comprising a biocompatible and preferably biodegradable cross-linked polymer and at least one biocompatible and preferably biodegradable support layer, wherein a gradient is preferably formed with respect to the mechanical and/or physical properties of one or more layers of the at least one set of layers comprising a biocompatible and biodegradable cross-linked polymer and/or the at least one biocompatible and preferably biodegradable support layer. The at least one support layer preferably comprises a biocompatible and preferably biodegradable meltable polymer and/or a biocompatible and incorporable material. This biocompatible and preferably biodegradable gradient layer system may be used as a biomaterial for regenerative medicine, particularly as a wound dressing or for tissue support. The present invention also provides means utilizing said inventive gradient layer system and methods for producing same.
