  • Publication number: 20250152772
    Abstract: A polymerisable composition for use as an adhesive for biological tissue, in particular for non-mineralised biological tissue, including an acrylate-type polymerisable monomer, a photoinitiator and a photopolymerisable resin. In particular, the composition of the invention makes it possible, after polymerisation, to adhere pieces of biological tissue to each other, to adhere a material to biological tissue, to form a surgical sealant or to form a skin dressing.

  • Publication number: 20220073686
    Abstract: The invention relates to a copolymer powder containing polyamide blocks and polyether blocks having: an enthalpy of fusion of the polyamide blocks of greater than or equal to 70 J/g if the weight ratio of the polyamide blocks relative to the polyether blocks of the copolymer is greater than or equal to 4; an enthalpy of fusion of the polyamide blocks of greater than or equal to 50 J/g if the weight ratio of the polyamide blocks relative to the polyether blocks of the copolymer is greater than or equal to 1 and less than 4; or an enthalpy of fusion of the polyamide blocks of greater than or equal to 20 J/g if the weight ratio of the polyamide blocks relative to the polyether blocks of the copolymer is less than 1.
