    • A heart valve assembly includes a base including a multi-lobular annular shape within a plane, a valve member or other annular body including a multi-lobular shape complementary to the shape of the base, and cooperating connectors on the base and the annular body for connecting the annular body to the base. The base includes an anchoring ring, and a flexible cuff for attaching the base to a biological annulus. The base and the annular body include guides for aligning their multi-lobular shapes, e.g., visual, tactile, or other markers, or tethers that extend from the base that are slidable through the annular body. During use, the base is attached to a biological annulus, the annular body is directed adjacent the annulus, oriented such that the multi-lobular shape of the annular body valve member is aligned with the base, and the annular body is attached to the base.
    • 心脏瓣膜组件包括在平面内包括多小叶状环状的基部,阀构件或包括与基部的形状互补的多小叶形状的其它环形体,以及基部和环形体上的配合连接器, 将环形体连接到基座。 底座包括一个固定环,和一个用于将基座连接到生物环的柔性箍。 基部和环形体包括用于对准其多小叶形状的引导件,例如从底部延伸的视觉,触觉或其它标记或系绳,其可滑动通过环形体。 在使用过程中,基座附接到生物环形区域,环形体被定向成邻近环形区域,定向成使得环形体阀构件的多小叶形状与基部对准,并且环形体附接到基部 。
