Abstract
Embodiments of the present disclosure are directed to prosthetic valves and methods of use thereof. In one implementation, an expandable annular valve body may include a plurality of atrial anchoring arms and ventricular anchoring legs extending therefrom. The anchoring arms and anchoring legs may be configured to assume a delivery configuration in which they are radially constrained, such as within a delivery device, and a deployed configuration, in which they may deflect radially outward. The anchoring legs may deflect radially outward by less than 90° when transitioning from the delivery configuration to the deployed configuration. Portions of the anchoring arms may deflect radially outward by at least 90° when transitioning from the delivery configuration to the deployed configuration.
