NOVEL NATURAL POLYMER-BASED MATERIAL WITH IMPROVED PROPERTIES FOR USE IN HUMAN AND VETERINARY MEDICINE AND THE METHOD OF MANUFACTURING SUCH

摘要

The invention is concerned with relatively dense and fluid expandable natural polymer-based membrane, preferably collagen-based material, with improved mechanical, physical, functional, and handling properties for use in human and veterinary medicinal applications. The membranous material is preferably collagen, and optionally contains additional biologically active substances such as hemostatic agents, growth factors, cytokines, hormones, drugs and the like, and/or biologically important and tissue-compatible inorganic or/and organic substances or/and their derivatives which can improve the mechanical, functional and handling properties of the material. The membrane is obtainable by simultaneous heat and pressure treatment of a basic natural polymer material for short periods of time.
