1. A cardiac valve prosthesis, comprising:
- only a first anchor frame consisting of a first single frame member that forms a ring around a common axis, where an infinitely vast plane parallel with and passing through the common axis and extending beyond an overall width and an overall height of the single frame member can only pass through two portions of the first single frame member to define a cross-sectional profile for each of the two portions having only one contiguous edge, and where the first single frame member has an inner portion defining an opening through the first anchor frame and an upper portion generally orthogonal to the inner portion;
two or more leaflets coupled to the first anchor frame; and
a pair of anchor members vertically extending from an apex of the first single frame member, the pair of anchor members restrained under tension in a first predetermined shape with a deployment member passing between the pair of anchor members, where the pair of anchor members moves toward a second predetermined shape when the deployment member is removed from between the pair of anchor members.

8. A cardiac valve prosthesis, comprising:
-
a first anchor frame having a first single frame member that forms a ring around a common axis to define an opening through the first anchor frame and a plurality of apexes; two or more leaflets coupled to the first anchor frame; and one or more anchor members vertically extending from each one of the plurality of apexes of the first single frame member. - View Dependent Claims (9, 10, 11, 12, 13, 14)
