An intraparietal aortic valve reinforcement device and a reinforced biological aortic valve

摘要

A reinforcement device (10) for a biological valve (20) includes an arrangement of supports (14(a)-(14(c) and 16(a)-16(c)) configured to establish a double-trigone geometry in the valve (20) and coupled to a base (12) upon which the valve (20) may be mounted. A plurality of commissural supports (14(a)-14(c)) establish the geometry of a commissural trigone, and a plurality of intercommissural supports (16(a)-16(c)) 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.
