1. A bi-leaflet prosthetic heart valve, comprising:

  • a substantially circular valve ring having an inner circumference defining a flow channel for blood flow;

    an axle secured to said valve ring, said axle being parallel to but not co-linear with a diameter of said valve ring;

    two substantially half-moon shaped leaflets hingedly connected to said axle and pivoting independently of each other, said leaflets having different cross-sectional areas, said leaflets moving between a closed position wherein the leaflets both are substantially in a plane of said valve ring and substantially occlude a flow of blood through said flow channel, and an open position wherein each of said leaflets are pivoted about said axle with respect to said closed position thereby permitting blood to flow through said flow channel.
