Abstract
Embodiments of the present disclosure are directed to prosthetic valves and methods of use thereof. In one implementation, an annular valve body may include a plurality of atrial anchoring arms and ventricular anchoring legs configured to extend therefrom. The anchoring arms and anchoring legs may be configured to assume a delivery configuration in which they are substantially parallel to a longitudinal axis of the valve body, and a deployed configuration, in which they may deflect radially outward. The anchoring arms may include a pivoting portion configured to extend in a non-ventricular direction when the arm is in the delivery configuration and in a ventricular direction when the arm is in the deployed configuration. The entire length of each leg may be configured to extend in a non-ventricular direction when the legs are in both the delivery and deployed configurations.
