  • Biomedical foam articles
    Patent number: 8197835
    Abstract: The present invention relates to biomedical foam articles for the wound sector which are formed by spraying a polymeric dispersion onto a wound. The polymeric dispersion being sprayed onto a wound surface forms a three-dimensional body which conforms to the spatial shape of the wound and which, as well as covering the wound surface, ensures a complete and accurately fitted packing of the wound in the depth dimension as well as the other dimensions. The biomedical foam articles of the present invention are particularly useful for treating chronic wounds.
