Abstract

A cardiac device comprises a first anchoring element configured to be attached to a first side of a tissue wall, a second anchoring element configured to be attached to a second side of the tissue wall, and a cinching device. The cinching device is configured to attach to the first anchoring element and the second anchoring element and apply force to the first anchoring element to move the first anchoring element towards the second anchoring element and at least partially compress the tissue wall.

First claim

What is claimed is:

1. A cardiac device comprising:
a first anchoring element configured to be anchored to a first side of a tissue wall, the first anchoring element having a cylindrical shape, wherein a diameter of the first anchoring element is less than a length of the first anchoring element;
a second anchoring element configured to be anchored to a second side of the tissue wall; and
a cinching device comprising a tube attached to and extending between the first anchoring element and the second anchoring element, the tube configured to:
extend through the tissue wall; and
apply force to the first anchoring element to move the first anchoring element towards the second anchoring element and at least partially compress the first side of the tissue wall.

2. The cardiac device of claim 1 , wherein the first anchoring element is configured to form an indentation at the first side of the tissue wall.

3. The cardiac device of claim 1 , wherein the first anchoring element is configured to form a flow channel at the first side of the tissue wall.

4. The cardiac device of claim 3 , wherein the flow channel is situated below an aortic valve to facilitate blood flow into the aortic valve.

5. The cardiac device of claim 4 , wherein the first anchoring element is configured to anchor to the first side of the tissue wall with the length of the first anchoring element extending in line with an aorta.

6. A cardiac device comprising:
a first anchoring element configured to be anchored to a first side of a tissue wall and configured to form a flow channel at the first side of the tissue wall;
a second anchoring element configured to be anchored to a second side of the tissue wall; and
a cinching device comprising a tube attached to and extending between the first anchoring element and the second anchoring element, the tube configured to:
extend through the tissue wall; and
apply force to the first anchoring element to move the first anchoring element towards the second anchoring element and at least partially compress the first side of the tissue wall.

7. The cardiac device of claim 1 , wherein the cinching device is rigid.

8. The cardiac device of claim 1 , wherein the cinching device is flexible.

9. The cardiac device of claim 1 , wherein the cinching device comprises one or more rigid mechanisms.

10. The cardiac device of claim 9 , wherein the tube comprises one or more rigid mechanisms.

11. The cardiac device of claim 1 , wherein the tube comprises one or more mechanisms configured to move the first anchoring element towards the second anchoring element and at least partially compress the first side of the tissue wall.

12. The cardiac device of claim 11 , wherein the one or more mechanisms comprise a notch.

13. The cardiac device of claim 1 , wherein the cinching device comprises multiple tubes.

14. The cardiac device of claim 6 , wherein the tube comprises one or more rigid mechanisms.

15. The cardiac device of claim 6 , wherein the tube comprises one or more mechanisms configured to move the first anchoring element towards the second anchoring element and at least partially compress the first side of the tissue wall.

16. The cardiac device of claim 15 , wherein the one or more mechanisms comprise a notch.

17. The cardiac device of claim 6 , wherein the cinching device comprises multiple tubes.

18. A method comprising:
anchoring a first anchoring element to a first side of a tissue wall, the first anchoring element having a cylindrical shape, wherein a diameter of the first anchoring element is less than a length of the first anchoring element;
anchoring a second anchoring element to a second side of the tissue wall;
attaching a cinching device comprising a tube to the first anchoring element and the second anchoring element;
extending the cinching device and tube through the tissue wall; and
applying force, via the tube, to the first anchoring element to move the first anchoring element towards the second anchoring element and at least partially compress the first side of the tissue wall.

19. The method of claim 18 , further comprising tightening the tube to apply force to the first anchoring element to move the first anchoring element towards the second anchoring element and at least partially compress the first side of the tissue wall.

20. The method of claim 18 , wherein the cinching device comprises multiple tubes.
