Prosthetic valve with separably-deployable valve body and tissue anchors
First Claim
1. A method of implanting a prosthetic valve within a native mitral valve, the method comprising:
- delivering the prosthetic valve into a heart chamber while the prosthetic valve is constrained in a radially-contracted delivery configuration, wherein the prosthetic valve includes;
an annular valve body comprising an annular outer frame and an inner frame situated at least partially within the outer frame,a plurality of ventricular anchors configured to extend from the outer frame, anda plurality of atrial anchors configured to extend from the inner frame,wherein the outer frame and the inner frame are secured against relative axial movement by at least one connector;
unconstraining the plurality of ventricular anchors and the plurality of atrial anchors while maintaining the valve body in the radially-contracted delivery configuration; and
unconstraining the valve body from the radially-contracted delivery configuration while the unconstrained atrial anchors are positioned within an atrium and while the unconstrained ventricular anchors are positioned within a ventricle, wherein unconstraining the valve body decreases a longitudinal distance between terminal ends of the unconstrained ventricular anchors and terminal ends of the unconstrained atrial anchors, such that native mitral valve tissue is clamped between the ventricular anchors and atrial anchors.

Abstract
Embodiments of the present disclosure are directed to prosthetic valves and methods of use thereof. In one implementation, a method of implanting a prosthetic valve within a native mitral valve may be provided. The method may include delivering the prosthetic valve into a heart chamber. The prosthetic valve may be constrained in a contracted delivery configuration. The prosthetic valve may include an annular valve body with a plurality of ventricular anchors and a plurality of atrial anchors attached thereto. The method may also include unconstraining the plurality of ventricular anchors and the plurality of atrial anchors while maintaining the valve body in the contracted delivery configuration. The method may also include unconstraining the valve body from the contracted delivery configuration while the unconstrained atrial anchors are positioned within an atrium and while the unconstrained ventricular anchors are positioned within a ventricle.
