  • Patent number: 10588741
    Abstract: A mitral valve prosthesis can be delivered within the native mitral annulus. The valve prosthesis has a valve component on which prosthetic valve leaflets are attached, and a lower support which anatomically and dynamically conforms to a native mitral valve annulus and which is flexibly attached to the valve component. The valve prosthesis can be delivered to the native mitral valve annulus in a collapsed configuration in which the valve component and anchoring element are serially rather than concentrically positioned to one another, thereby minimizing the diameter of the valve prosthesis during delivery. The devices and methods described are useful for treatment of various mitral valve disorders which result in, for example, mitral regurgitation.

  • Publication number: 20180263768
    Abstract: A heart valve prosthesis and methods of its implantation are described herein. The prosthesis can be implanted in a heart of a patient by positioning an upper support of an anchoring element into a left atrium of the patient. The upper support can expand adjacent to a native valve structure of the patient. Further, the upper support can be moved against the native valve structure in a direction toward a left ventricle of the patient. A lower support of the anchoring element can be positioned into the left ventricle, spaced apart from the upper support, the lower support being separate from the upper support and coupled to the upper support by a flexible connector. Finally, the lower support can expand within the left ventricle, and engagement members of the lower support can engage with tissue of the native valve structure.
