Abstract
An atrioventricular prosthesis device is provided. The device includes a frame at least partially defining and enclosing a central cavity, the frame having a distal portion, a proximal portion, and a middle portion connected therebetween. The device further includes a valve construct formed, at least in part, from a cell growth scaffold, at least partially disposed within the central cavity defined by the frame. The valve construct includes: an annular portion defining an aperture and being connected to the frame for positioning the valve construct within the central cavity of the frame, and a plurality of leaflets extending longitudinally and radially inward from the annular portion. The frame and valve construct are transitionable to a deployed state, in which a diameter of at least a portion of the frame and the valve construct substantially conform to a diameter of a tricuspid and/or mitral valve opening.
