ABSTRACT:
An apparatus helps improve operation of a heart valve. The apparatus includes an arcuate base portion having a central axis and a buttress extending from the base portion axially relative to the base portion. The buttress has a first surface and an opposite second surface. The first surface is dimensioned and configured to be engaged by a first leaflet of the heart valve when the apparatus is implanted in the heart valve. The second surface is dimensioned and configured to be engaged by a second leaflet of the heart valve when the apparatus is implanted in the heart valve. The buttress permits flow of blood adjacent both the first surface of the buttress and the second surface of the buttress when the first and second leaflets are not engaging the buttress.
