Valve locking mechanism

1. A valve replacement implant, comprising:

an expandable anchor member having a proximal end and a distal end, the anchor member being actuatable between a delivery configuration and a deployed configuration;

a plurality of locking mechanisms configured to secure the anchor member in the deployed configuration, each locking mechanism including:

an axially movable post including a leg portion extending radially inwardly therefrom at an acute angle; and

a receiving portion fixed to the anchor member, the receiving portion being configured to slidably receive the post;

a plurality of valve leaflets disposed within a central lumen of the anchor member, the plurality of valve leaflets being secured to the leg portions of the plurality of locking mechanisms;

wherein the plurality of locking mechanisms is releasably attached to a delivery device;

wherein the anchor member is actuated between the delivery configuration and the deployed configuration by translating the post proximally relative to the receiving portion.

2. The valve replacement implant of claim 1 , wherein the leg portion extends from the post toward the proximal end.

3. The valve replacement implant of claim 1 , wherein the leg portion is attached to the post at a distal end of the post.

4. The valve replacement implant of claim 1 , wherein the leg portion is flexibly attached to the post.

5. The valve replacement implant of claim 1 , wherein the leg portion includes a free end and a secured end, the leg portion being attached to the post at the secured end.

6. The valve replacement implant of claim 5 , wherein the free end is unattached to any other structure except through the leg portion.

7. The valve replacement implant of claim 1 , wherein at least part of the leg portion longitudinally overlaps the receiving portion along a central longitudinal axis of the anchor member in the deployed configuration.

8. The valve replacement implant of claim 1 , wherein the plurality of valve leaflets is secured directly to the leg portions.

9. The valve replacement implant of claim 1 , wherein the plurality of valve leaflets is not directly secured to the posts.

10. The valve replacement implant of claim 1 , wherein the post includes two leg portions extending inwardly therefrom.

11. The valve replacement implant of claim 10 , wherein the two leg portions are joined together at a free end opposite the post.

12. The valve replacement implant of claim 10 , wherein the two leg portions are arranged generally parallel to each other.

13. The valve replacement implant of claim 10 , wherein at least some of the plurality of valve leaflets pass between the two leg portions.

14. The valve replacement implant of claim 13 , wherein the at least some of the plurality of valve leaflets passing between the two leg portions wrap around the two leg portions.

15. The valve replacement implant of claim 14 , wherein the at least some of the plurality of valve leaflets passing between the two leg portions and wrapping around the two leg portions are secured back to themselves.

16. The valve replacement implant of claim 15 , wherein the at least some of the plurality of valve leaflets are secured back to themselves using one or more sutures.

17. The valve replacement implant of claim 15 , wherein the at least some of the plurality of valve leaflets are secured back to themselves using an adhesive.

18. The valve replacement implant of claim 1 , wherein a distalmost end of the post is coupled to the distal end of the anchor member.

19. The valve replacement implant of claim 1 , wherein a distalmost end of the plurality of valve leaflets is coupled to the distal end of the anchor member.
