<p>An annuloplasty prosthesis (10) for supporting an annulus (36) of a heart valve (38) includes a substrate material (12) over which a covering (20) of a biocompatible and biological tissue material is applied. The substrate (12) may be formed of a generally rigid material (e.g., a plastic or metal) in which the substrate (12) has a predetermined shape corresponding to an annulus (36) of the heart valve (38). Alternatively, the substrate (12) may be formed of flexible material (e.g., a soft cloth or natural tissue), which may be adjusted at implantation to accommodate the size and configuration of annulus (36).</p> |
