Abstract
A method for the suture of wounds, includes applying a sufficient quantity of a biocompatible, bio-adhesive mixture with at least 50% by weight of a methylidene malonate-based composition containing:40 to 100% by weight of at least one methylidene malonate of formula (I):  in which:A and B independently represent a group (a) or (b): in which R1 and R2 independently represent a linear or branched alkyl group with 1 to 6 carbon atoms, n is an integer between 1 and 5, and at least one of A and B represents a (b) group;and/or one or more methylidene malonate oligomers with a molecular weight less than or equal to 6,000 and including recurrent units of formula (II): in which A and B are as defined above; and0 to 60% by weight of at least one methylidene malonate polymer with a molecular weight greater than 6,000 and including recurrent units of formula (II).
