摘要：
The invention provides biodegradable polymeric hydrogel matrices having excellent durability and swellability. The matrices are formed from a combination of poly-α(1→4)glucopyranose macromer and a biocompatible biostable hydrophilic macromer. 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, and is able to be degraded at the target site after period of time.
