Beschreibung
Zusammenfassung:	A contraceptive and a related device are provided. An intravaginal ring for the controlled release of at least one bioactive agent may further contain at least one of a non-bioabsorbable microparticulate ion-exchanging polymer, a fully bioabsorbable polymeric matrix, a biostable hydrophilic elastomeric polymeric matrix, a biostable amphiphilic elastomeric polymeric matrix, a biostable elastomericpolymeric matrix containing an inorganic microparticulate, and a biostable elastomeric porous polymeric matrix, each to aid in the release and/or modulate the release of the bioactive agent. 一种避孕装置及相关装置。用于控制释放至少一种生物活性剂的阴道内环可以还含有非生物可吸收的微粒状离子交换聚合物、完全生物可吸收的聚合物基质、生物稳定的亲水性弹性聚合物基质、生物稳定的两亲性弹性聚合物基质、含有无机微粒物的生物稳定的弹性聚合物基质以及生物稳定的弹性多孔聚合物基质中的至少一种，各个物质有助于生物活性剂的释放和/或调节生物活性剂的释放。
