A heart valve assembly includes a base (12) including a multi-lobular annular shape within a plane, a valve member or other annular body (14) including a multi-lobular shape complementary to the shape of the base, and cooperating connectors (24) on the base and the annular body for connecting the annular body to the base. The base includes an anchoring ring (18), and a flexible cuff (20) 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 (50) 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.
Ensemble valve cardiaque comprenant une base (12) présentant une forme annulaire multi-lobulaire à l'intérieur d'un plan, une valve ou autre corps annulaire (14) présentant une forme multi-lobulaire complémentaire à la forme de la base et des raccords coopérant (24) sur la base et le corps annulaire afin d'accoupler le corps annulaire à la base. Cette dernière comprend un anneau d'ancrage (18) et une manchette flexible (20) servant à relier la base à un annulus biologique. La base et le corps annulaire possèdent des guides permettant d'aligner leurs formes multi-lobulaires, par exemple, visuels, tactiles ou d'autres indicateurs ou éléments de liaison (50) s'étendant depuis la base et pouvant coulisser à travers le corps annulaire. Pendant l'utilisation, la base est fixée à un annulus biologique, le corps annulaire est dirigé en position contiguë à l'annulus, orienté de façon à aligner sur la base la forme multi-lobulaire de la valve du corps annulaire et à fixer ce corps annulaire à la base.
