The invention is concerned with novel natural polymer-based material and preferably collagen-based material with improved mechanical, physical, functional and handling properties for use in human and veterinary medicine in both in vivo and in vitro condition, wherein the material is a natural polymer, preferably collagen, of animal or/and human or/and recombinant or/and transgenic origin optionally additionally containing 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. This novel material is obtainable by simultaneous heat and pressure treatment of a basic natural polymer material. Such process for the manufacture of the novel material is a further subject of the present invention.

La présente invention concerne un nouveau matériau à base de polymère naturel, de préférence à base de collagène, qui présente des propriétés mécaniques, physiques, fonctionnelles et de manipulation améliorées et est destiné à un usage en médecine humaine ou vétérinaire, à la fois dans des conditions in vivo et in vitro. Selon cette invention, ce matériau est un polymère naturel, de préférence du collagène, d'origine animale et/ou humaine et/ou de recombinaison et/ou transgénique, qui contient éventuellement, en plus, des substances biologiquement actives, telles que des agents hémostatiques, des facteurs de croissance, des cytokines, des hormones, des médicaments et des substances similaires, et/ou des substances inorganiques et/ou organiques, biologiquement importantes et compatibles avec les tissus et/ou leurs dérivés, qui permettent d'améliorer les propriétés mécaniques, fonctionnelles et de manipulation. Ce nouveau matériau peut être obtenu par traitement thermique et sous pression simultané d'un matériau à base de polymère naturel basique. La présente invention concerne également un tel procédé de production dudit nouveau matériau.
