A composition comprising a synthetic polymer, optionally in the presence of a drug, where the polymer comprises multiple activated groups. The multiple activated groups are reactive with functionality present on animal tissue, so that upon administration of the polymer to the tissue, the polymer binds to the tissue. Alternatively, the multiple activated groups are reactive with functionality present on a non-living surface, where the polymer binds to this surface to, e.g., increase the lubricity of the surface. When drug is present in the composition, the drug is then delivered to the site of polymer attachment.
一种组合物包括一种合成聚合物,可选地存在药物,并且该聚合物包括多个活性基团。这些多个活性基团与动物组织上存在的功能性反应,因此在将聚合物注射到组织中时,聚合物与组织结合。或者,这些多个活性基团与非生物表面上存在的功能性反应,聚合物将与该表面结合,例如增加表面的润滑性。当组合物中存在药物时,药物将被传递到聚合物附着的部位。
