Heart valve prosthesis

TLDR
In this article, a heart valve prosthesis incorporating a dynamic stiffener element is disclosed, which allows normal movement of the annulus during the cardiac cycle while providing mechanical support to the valve annulus so as to maintain the valve leaflets in proper physiological alignment.
Abstract
A heart valve prosthesis incorporating a dynamic stiffener element is disclosed. The prosthesis is adapted for securement to the annulus of an atrioventricular valve and has the characteristic of allowing normal movement of the annulus during the cardiac cycle while providing mechanical support to the valve annulus so as to maintain the valve leaflets in proper physiological alignment. The stiffener element has a plurality of reciprocating members allowing it to be modifiable in shape so as to be capable of assuming the optimum shape for a particular heart valve.
