An intra-annular mounting frame (10) useful for, inter alia, restoring the geometry of a valve to achieve proper coaptation. Intra-annular hemispherical mounting frame (10) is inserted into the aortic valve annulus and provides for the reconstruction of the native aortic valve. Intra-annular hemispherical mounting frame (10) includes a plurality of curvatures (12) and also interconnecting points (14). Generally, curvature (12) conforms to the annular cusp geometry with interconnecting points (14) conforming to the geometry of the commissures. Curvatures (12) curve in about a first plane and a second plane of hemispherical mounting frame (10) to correspond to the three-dimensional geometry of the cusps of an aortic valve.

L'invention concerne un cadre de montage intra-annulaire (10) utile, entre autres, pour restaurer la géométrie d'une valve afin d'obtenir une coaptation correcte. Un cadre de montage hémisphérique intra-annulaire (10) est inséré dans l'anneau de la valve aortique et permet la reconstruction de la valve aortique originelle. Le cadre de montage hémisphérique intra-annulaire (10) comprend une pluralité de courbures (12), ainsi que des points d'interconnexion (14). Généralement, la courbure (12) se conforme à la géométrie annulaire de la cuspide et les points d'interconnexion (14) se conforment à la géométrie des commissures. Les courbures (12) se courbent dans un premier plan et un second plan du cadre de montage hémisphérique (10) afin de correspondre à la géométrie tridimensionnelle des cuspides d'une valve aortique.
