ABSTRACT:
A bi-leaflet prosthetic heart valve including a substantially circular valve ring having an inner circumference defining a flow channel for blood flow. An axle secured to the valve ring. The axle is parallel to but not co-linear with a diameter of the valve ring. Two substantially half-moon shaped leaflets are hingedly connected to the axle and pivot independently of each other. The leaflets have different cross-sectional areas. The leaflets move between the closed position wherein the leaflets are both substantially in a plane of the valve ring and substantially include a flow of blood through the flow channel and an open position wherein each of the leaflets are pivoted about the axle with respect to the closed position, thereby permitting blood to flow through the flow channel.
