MRI-VISIBLE HYDROPHOBIC COPOLYMER

摘要

The invention relates to a hydrophobic thermoplastic copolymer which is in particular of use for manufacturing and/or coating medical devices, in particular implantable medical devices, characterized in that it is obtained by copolymerization, and in that it comprises at least one first monomer unit and at least one second monomer unit onto which is grafted a paramagnetic-ion-chelating ligand which can complex with such a paramagnetic ion or a paramagnetic-ion-chelating ligand which is complexed with such a paramagnetic ion, wherein the second monomer unit is grafted in sufficient amount for the copolymer to be visible in magnetic resonance imaging when it is complexed with said paramagnetic ion. The invention also relates to a method for obtaining said hydrophobic thermoplastic copolymer.

1. A hydrophobic thermoplastic copolymer, comprising:
a first monomer unit, and a second monomer unit on which is grafted a paramagnetic-ion-chelating ligand that optionally complexes with a paramagnetic ion or a paramagnetic-ion-chelating ligand complexed with the paramagnetic ion, wherein the second monomer unit is grafted in sufficient amount for the copolymer to be visible in magnetic resonance imaging when the second monomer unit is complexed with the paramagnetic ion.
