Implantable prosthetic valves and methods relating to same
First Claim
1. A prosthetic valve consisting of:
- a saddle-shaped annulus, a pair of leaflets connected to the annulus, and a pair of support elements, each of the support elements connected to the leaflets, each of the leaflets separated from one another by each support element, the annulus adapted to move back and forth from a generally concave state to a generally convex state, the pair of leaflets adapted to define an opening when the annulus is in the generally concave state and to define a seal when the annulus is in the generally convex state;
wherein when the valve is implanted in a mitral position, pressure change between diastole and systole cause a geometrical change resulting in opening and closure of the valve leaflets, respectively, with annulus deflection.

Abstract
In accordance with one embodiment of the present disclosure, a prosthetic valve is provided. The prosthetic valve includes an annulus, a pair of leaflets, and a pair of support elements. The annulus has a generally saddle-shape formed by a movable pair of first portions separated from each other by a movable pair of second portions. The pair of leaflets extend from the annulus and are separated from each other by the pair of support elements. The first portions of the annulus and the second portions of the annulus are configured to move back and forth from being generally concave to being generally convex such that any movement of the first portions of the annulus occurs at generally the same time as any movement of the second portions of the annulus.
