Abstract
A valve body assembly for being mounted adjacent an annulus within a heart. A first retainer is attached to the valve body assembly for engaging a first side of the annulus. A second retainer is attached to the valve body assembly and includes a resiliently-deformable retaining member for resiliently engaging a second side of the annulus. The resiliently deformable retaining member is collapsed to a size permitting it to be inserted into through the annulus and positioned adjacent the second side of the annulus. The retaining member is then allowed to expand such that it resiliently engages the second side of the annulus.
