First Claim
Patent Images
1. An annuloplasty prosthesis for supporting an annulus of a heart valve, comprising:
- a tubular sheath of a biocompatible animal tissue material having a lumen within the sheath;
a length of a substrate disposed within the lumen to facilitate implantation of the sheath at the annulus of the heart valve; and
an implantation flange extending from a sidewall portion of the tubular sheath.

Abstract
An annuloplasty prosthesis for supporting an annulus of a heart valve includes a substrate material over which a covering of a biocompatible and biological tissue material is applied. The substrate may be formed of a generally rigid material (e.g., a plastic or metal) in which the substrate has a predetermined shape corresponding to an annulus of the heart valve. Alternatively, the substrate 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.
