    • The present invention relates to compositions for treating a disease, such as diabetes, by implanting encapsulated biological material into a patient in need of treatment. Several methods are presented for coating several different types of biological materials. The coatings can be placed directly onto the surface of the biological materials or onto the surface of other coating materials that hold the biological materials. The components of the polymerization reactions that produce the coatings can include natural and synthetic polymers, macromers, accelerants, cocatalysts, photoinitiators, and radiation. These encapsulated biological materials are used to treat a variety of different human and animal diseases or disorders by implanting them into several areas in the body including the subcutaneous site. The coating materials can be manipulated to provide different degrees of biocompatibility, protein diffusivity characteristics, strength, and biodegradability to optimize the delivery of biological materials from the encapsulated implant to the host recipient while protecting the encapsulated biological materials from destruction by the host inflammatory and immune protective mechanisms without requiring long-term anti-inflammatory or anti-immune treatment of the host.
    • 本发明涉及通过将包封的生物材料植入需要治疗的患者中来治疗疾病如糖尿病的组合物。 介绍了几种不同类型的生物材料的方法。 涂层可以直接放置在生物材料的表面上或其它涂覆材料的表面上。 产生涂层的聚合反应的组分可以包括天然和合成聚合物,大分子单体,促进剂,助催化剂,光引发剂和辐射。 这些包封的生物材料用于通过将它们植入人体的包括皮下部位的几个区域来治疗各种不同的人和动物疾病或病症。 可以操作涂层材料以提供不同程度的生物相容性,蛋白质扩散性特征,强度和生物降解性,以优化从包封的植入物到宿主受体的生物材料递送,同时保护包封的生物材料免受宿主炎症和免疫的破坏 不需要对宿主进行长期抗炎或抗免疫治疗的保护机制。
