摘要： Polymers with non-leaching antimicrobial activity and their use as surface coatings or bulk resins for medical devices. The antimicrobial polymers are prepared with antimicrobial moieties covalently bonded to a polymer chain end or to a polymer backbone at a side chain end. The antimicrobial moiety-containing endgroups include surface active (or surface assembling) moieties which promote enrichment of antimicrobial endgroups at the polymer surface and thus formation of an antimicrobially active surface. Polymers with built-in antimicrobial endgroups can be used as bulk resins, as antimicrobial additives, or as infection preventative coatings in the manufacture of medical devices (e.g., catheters, vascular access devices, peripheral lines, IV sites, drains, gastric feeding and tubes, and other implantable devices). Such materials can also be used as antimicrobial and antifouling coatings on structures in contact with microorganism in environments that require control of biofilm formation, such as marine products.

摘要： Amphiphilic biomimetic phosphorylcholine-containing silicone compounds for use in both topical and internal applications as components in biomedical devices. The silicone compounds, which include zwitterionic phosphorylcholine groups, may be polymerizable or non-polymerizable. Specific examples of applications include use as active functional components in ophthalmic lenses, ophthalmic lens care solutions, liquid bandages, wound dressings, and lubricious and anti-thrombogenic coatings.
摘要翻译：用于局部和内部应用的两亲仿生磷酰胆碱的硅氧烷化合物作为生物医学装置的组件。包含两性离子磷酰胆碱基团的硅氧烷化合物可以是可聚合的或不可聚合的。应用的具体实例包括用作眼科镜片中的活性功能组分，眼用晶状体护理溶液，液体绷带，伤口敷料以及润滑和抗血栓形成的涂层。
