First Claim
Patent Images
1. A reinforcement device comprising:
- a plurality of commissural supports, each commissural support being configured to stabilize a valve wall of a biological valve at a commissure of the biological valve, the biological valve having an inflow region and an outflow region;
a plurality of intercommissural supports, each intercommissural support being configured to stabilize the valve wall at a location circumferentially between two of the commissures; and
a base disposed at the inflow region of the biological valve, the base being attached to the plurality of commissural supports and the plurality of intercommissural supports, the base further being configured to receive the biological valve mounted thereon, wherein the commissural supports and intercommissural supports are discontinuous around the valve wall in the outflow region of the biological valve.

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.

33. A reinforced prosthetic valve comprising:
-
a biological valve having leaflets attached to an external wall at commissures, the biological valve having an inflow region and an outflow region, the biological valve being mounted on a base; a plurality of commissural supports extending from the base, each commissural support configured to stabilize the external wall at one of the commissures; and a plurality of intercommissural supports extending from the base, each intercommissural support being configured to stabilize the external wall at a location circumferentially between two of the commissures, wherein the commissural supports and intercommissural supports do not continuously surround the valve in the outflow region. - View Dependent Claims (34, 35, 36)
