Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
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.

Claim 3
Dependent Claim
22 words
The method of claim 1 , wherein forming the first anchor frame includes forming the first anchor frame with a predetermined circumference.
Claim 4
Dependent Claim
49 words
The method of claim 1 , including positioning a first inflatable balloon at least partially within the opening through the first anchor frame; and inflating the first inflatable balloon to expand the first anchor frame of the cardiac valve from a first predetermined configuration to a fully deployed configuration.
Claim 5
Dependent Claim
32 words
The method of claim 1 , including releasing the pair of two or more anchor members from their uncrossed relationship by removing the deployment member from between the pair of anchor members.
Claim 6
Dependent Claim
33 words
The method of claim 1 , including providing a sealing material on the first anchor frame to prevent leakage of the liquid outside of the opening after anchoring the cardiac valve to tissue.
Claim 7
Dependent Claim
16 words
The method of claim 1 , including reversibly joining the cardiac valve to a delivery catheter.
Claim 8
Dependent Claim
34 words
The method of claim 6 , wherein reversibly joining the cardiac valve and the delivery catheter includes constraining the first anchor frame of the cardiac valve a first predetermined configuration on the delivery catheter.
Claim 9
Dependent Claim
26 words
The method of claim 7 , wherein constraining the first anchor frame includes constraining the first anchor frame in a retractable sheath of the delivery catheter.
Claim 10
Dependent Claim
43 words
The method of claim 7 , including attaching the first anchor frame to placement guides, where the placement guides can extend from the delivery catheter to allow the first anchor frame to expand from the first predetermined configuration to the fully deployed configuration.
