Abstract
Prosthetic valves and methods of using prosthetic valves may be provided. In one implementation, an expandable annular valve body may include a plurality of atrial anchoring arms and ventricular anchoring legs extending radially outward therefrom. At least one atrial anchoring arm may include a rigid portion and a flexible portion positioned radially outwards from the rigid portion. At least one atrial anchoring arm and at least one ventricular anchoring leg may be arranged such that a proximal section of the flexible portion of the at least one atrial anchoring arm and a terminal leg end of the at least one ventricular anchoring leg are substantially equidistant from a longitudinal axis extending through the center of the annular valve body.
