Patent ID: 7722666

Claim:
A method of making a cardiac valve prosthesis, comprising: forming only a first anchor frame consisting of a first single frame member having a ring configuration around a common axis, where a 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 a surface defining an opening through the first anchor frame; forming pairs of anchor members on the first anchor frame, wherein the pairs of anchor members vertically extend over the surface defining the opening; restraining the pairs of anchor members 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; and coupling two or more leaflets to the first anchor frame for unidirectional flow of a liquid through the opening of the cardiac valve.
