  • Composition of diblock and triblock copolymers and the use thereof in the prevention of tissue adhesions
    Patent number: 10603414
    Abstract: Disclosed is a composition based on copolymers including at least one A-B block copolymer, wherein block A is a polyester and block B is a polyoxyethylene (PEG), and wherein the total molecular mass in weight of the PEG is higher than or equal to 50 kDa, and the ethylene oxide motif/ester motif molar ratio is between 0.5 and 5. The invention also relates to an anti-adhesive material including such a composition, used for the prevention of tissue adhesions and especially for the prevention of intrauterine synechiae.
    Type: Grant
    Filed: August 3, 2015
    Date of Patent: March 31, 2020

  • Hydrophobic polymer for producing medical devices visible in MRI
    Patent number: 9358324
    Abstract: The present invention relates to a hydrophobic polymer used in particular to produce and/or coat medical devices, in particular implantable medical devices, that are visible in magnetic resonance imaging, characterized in that it comprises at least one monomer unit on which is grafted a chelating ligand of a paramagnetic ion complexed with such a paramagnetic ion, said monomer unit having at least one carbonyl group, said monomer unit comprising, prior to grafting, at least one hydrogen atom in the ? position of said at least one carbonyl group, and said grafting of the chelating ligand taking place in the area of said at least one hydrogen atom in the ? position of said at least one carbonyl group.
