    Abstract: Embodiments of a prosthetic heart valve comprise an annular main body, an atrial cap extending radially outwardly from the atrial end of the main body, and a plurality of ventricular anchors extending outwardly from the ventricular end of the main body. Each ventricular anchor can have a proximal end portion connected to the ventricular end, an intermediate portion extending away from the atrial end and then back toward the atrial so as to define a first bend, and a free distal end portion that extends from the intermediate portion. The distal end portion can comprise a first section, a second section, and a second bend between the first and second sections, the first section extending from the intermediate portion in a direction toward the atrial end and radially away from the main body.

    Abstract: A mitral valve prosthesis includes an hourglass shaped inner frame and a bulbous outer frame. A valve body having a plurality of leaflets is positioned within an interior region of the inner frame. The leaflets are shaped to substantially conform to an interior surface of the inner frame when the leaflets are in an open position. As a result, the gap between the leaflets and the inner frame is decreased, thereby reducing the likelihood of thrombus formation. Ventricular anchors are preferably provided along a distal end of the inner frame. The anchors extend proximally for placement behind native mitral valve leaflets. A fabric skirt may extend along an inner or outer surface of the outer frame. In preferred embodiments, the fabric skirt extends distally beyond a distal end of the outer frame and is adapted for forming a seal along the mitral valve annulus.

    Abstract: A method of replacing the function of a native mitral valve is achieved by inserting a distal end portion of a delivery apparatus into a patient's body, wherein a prosthetic mitral valve is disposed along the distal end portion of the delivery apparatus. The prosthetic mitral valve includes a collapsible and expandable annular body having a network of struts interconnected at a plurality of nodes to form a plurality of open cells. Atrial and ventricular flanges are coupled to the annular body and extend radially away from the annular body. Three commissure support posts extend from the ventricular flange toward a ventricular end of the prosthetic valve and a valve member is secured to the commissure support posts. The prosthetic mitral valve is positioned within the native mitral valve of the patient's heart and the native mitral valve is pinched between the atrial and ventricular flanges.
