Abstract

A multilayer material with improved mechanical, physical, functional and handling properties for use in human and veterinary medicine for reconstruction of tissue or organs comprises at least two layers of a reconstituted natural polymer matrix, preferentially collagen, and optionally one or more layers comprising a biocompatible synthetic polymer which may be bioinert or biodegradable. The multilayer construct is prepared by simultaneously applying elevated heat and pressure to the combined layers for a short period of time sufficient to bond said layers but insufficient to denature said natural polymer. The materials of the layers may optionally contain biologically active substances or substances which improve mechanical, functional, biological and/or handling properties of the material.
