First Claim
Patent Images
1. A method of reinforcing a biological valve, the valve comprising leaflets attached to an external wall at commissures, the method comprising:
- securing a commissural support to the external wall approximately at each commissure;
coupling the commissural supports to a base;
securing an intercommissural support to the external wall between each pair of commissural supports; and
coupling the intercommissural supports to a base.

Abstract
A reinforcement device for a biological valve includes an arrangement of supports configured to establish a double-trigone geometry in the valve and coupled to a base upon which the valve may be mounted. A plurality of commissural supports establish the geometry of a commissural trigone, and a plurality of intercommissural supports establish the geometry of an intercommissural trigone. A method for reinforcing a biological valve includes using commissural supports in conjunction with intercommissural supports, both sets of supports coupled to a base upon which the valve is mounted.

16. A method of replacing a malfunctioning valve in a subject, the method comprising:
-
removing the malfunctioning valve from said subject; providing a reinforced biological valve comprising a plurality of commissural supports and a plurality of intercommissural supports, each commissural support being configured to stabilize a commissure of the biological valve, each intercommissural support being configured stabilize a wall of the biological valve between each pair of commissural supports, the commissural supports and intercommissural supports being disposed at discrete locations about an outflow region of the biological valve; and implanting said reinforced biological valve in said subject in place of said malfunctioning valve.
