An apparatus for helping improve operation of a heart valve includes a generally annular base and a buttress extending generally axially from and inwardly relative to an arc portion of the base. When the apparatus is when implanted at an annulus of a heart valve, the buttress thereof provides a surface with which a leaflet of the heart valve may move into and out of engagement for helping control blood flow relative to the apparatus and heart valve.
1. An apparatus for helping improve operation of a heart valve, comprising:a generally arcuate base portion; and a buttress extending generally radially inwardly and axially relative to the base portion so as to permit substantially bi-directional flow of blood axially relative to the apparatus, the
1. An apparatus for helping improve operation of a heart valve, comprising:a generally arcuate base portion; and a buttress extending generally radially inwardly and axially relative to the base portion so as to permit substantially bi-directional flow of blood axially relative to the apparatus, the buttress having a surface dimensioned and configured to be engaged by at least one leaflet of the heart valve when the apparatus is implanted at the heart valve, whereby when the apparatus is implanted at the heart valve, movement of the at least one leaflet of the heart valve relative to the surface of the buttress provides substantially unidirectional flow of blood relative to the apparatus.
