Publication number: 20250152772Abstract: 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.Type: ApplicationFiled: February 17, 2023Publication date: May 15, 2025Applicant: COHESIVESInventors: Bertrand PERRIN, Natacha GOUTAY
