Abstract
A heart valve with a structural stent and radially moveable cusps and commissures. The stent may be of three separate elements, each having a cusp portion and two commissure portions. The commissures may be pivotally or flexibly coupled, and may separate into independent leaflets. A connecting band may be provided that follows the cusps and commissures and extend outwardly. The valve may be connected to the natural tissue along the undulating connecting band. A multi-legged holder having legs alternating between each cusp and commissure may be used for implantation. A method of implantation is also disclosed, as is a system for implanting independent valve leaflets in the native annulus.
