    摘要: The invention provides biocompatible polymeric hydrogel matrices having excellent durability and swellability. The matrices are formed from a macromer and photo-polymer combination. The matrices can be used in association with a medical device or alone. In some methods the polymeric matrix is placed or formed at a target site in which the matrix swells and occludes the target area.
