摘要：
A heart valve assembly includes a base (12) including a multi-lobular annularshape within a plane, a valve member or other annular body (14) including amulti-lobular shape complementary to the shape of the base, and cooperatingconnectors (24) on the base and the annular body for connecting the annularbody to the base. The base includes an anchoring ring (18), and a flexiblecuff (20) for attaching the base to a biological annulus. The base and theannular body include guides for aligning their multi-lobular shapes, e.g.,visual, tactile, or other markers, or tethers (50) that extend from the basethat are slidable through the annular body. During use, the base is attachedto a biological annulus, the annular body is directed adjacent the annulus,oriented such that the multi-lobular shape of the annular body valve member isaligned with the base, and the annular body is attached to the base.
