    • Disclosed are biomedical devices having a hydrophilic coating on a portion of a surface thereof, the biomedical device comprising: (a) a biomedical device obtained from a polymerization product of a monomeric mixture comprising (i) a polymerizable monomer containing a boronic acid moiety and an electron withdrawing moiety; and (ii) a biomedical device-forming comonomer; and (b) a hydrophilic reactive polymer having complementary reactive functionalities along the polymer chain, wherein the complementary reactive functionalities along the polymer chain of the hydrophilic reactive polymer of (b) bind with the boronic acid moieties of the biomedical device of (a), thereby producing a biocompatible coating which can be removed and re-applied to restore the surface properties of the biomedical device to substantially as-new condition. Methods for treating the biomedical device are also disclosed.
    • 公开了在其表面的一部分上具有亲水涂层的生物医学装置,所述生物医学装置包括:(a)由单体混合物的聚合产物获得的生物医学装置,其包含(i)含有硼酸部分的可聚合单体和 吸电子部分; 和(ii)生物医学装置形成共聚单体; 和(b)沿着聚合物链具有互补的反应性官能团的亲水性反应性聚合物,其中沿着(b)的亲水性反应性聚合物的聚合物链的互补反应性官能团与(a)的生物医学装置的硼酸部分结合, 从而产生生物相容性涂层,其可以被去除并重新施加以将生物医学装置的表面性质恢复到基本上新的状态。 还公开了用于治疗生物医学装置的方法。
