    摘要： Biocompatible polymers are manufactured to include an amino acid mimetic monomer and one or more hydrophobic acrylate monomers. The amino acid mimetic monomers are selected to mimic the side chain of the amino acids asparagine or glutamine. The amino acid mimetic monomer can be a methacryloyl or acryloyl derivative of 2-hydroxyacetamide, 3-hydroxypropionamide, alaninamide, lactamide, or glycinamide. These amide functional groups offer the advantage of moderate hydrophilicity with little chemical reactivity. The amino acid mimetic monomer can be copolymerized with one or more hydrophobic acrylate monomers to obtain desired coating properties.

    摘要： A method of using a biocompatible polymer is used. Biocompatible polymers are manufactured to include an ammo acid mimetic monomer and one or more hydrophobic acrylate monomers. The amino acid mimetic monomers are selected to mimic the side chain of the amino acids asparagine or glutamine. The amino acid mimetic monomer can be a methacryloyl or acryloyl derivative of 2-hydroxyacetamide, 3-hydroxypropionamide, alaninamide, lactamide, or glycinamide. These amide functional groups offer the advantage of moderate hydrophilicity with little chemical reactivity. The amino acid mimetic monomer can be copolymerized with one or more hydrophobic acrylate monomers to obtain desired coating properties.

    摘要： Copolymers are manufactured to include a zwitterionic monomer (e.g., methacryloyloxyethyl phosphorylcholine monomer), a dihydroxyphenyl derivatized monomer, and optionally one or more additional monomers. The dihydroxyphenyl derivatized monomer gives the copolymers excellent adhesion properties. Optional monomers include a cationic amino monomer, a hydrocarbon monomer, and/or a hydrophilic monomer. The copolymers are biocompatible and can be used with medical devices.

    摘要： Medical devices are coated with terpolymers of tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride (THV). The mole fraction of tetrafluoroethylene can be in a range from about 0.005 to about 0.85, the mole fraction of hexafluoropropylene monomer can be in a range from about 0.005 to about 0.85, and the mole fraction of vinylidene fluoride can be in a range from about 0.005 to about 0.99. One example method of applying the terpolymers to a medical device includes dissolving the terpolymers in a solvent and applying the solution to the medical device and then removing the solvent. The THV coating on the implantable medical devices are advantageously biocompatible.
