Abstract

The cinching apparatus ( 800 ) comprising: an anchoring component having a distal end a proximal end; the distal end of the anchoring component having an engaging member ( 805 ). A locking component ( 815 ) and a tension member ( 820 ) wherein the anchoring component is enabled to be positioned on a first target site of a tissue component and the locking component ( 815 ) is enabled to be positioned on a second target site of a tissue component of the heart, and the tension member ( 820 ) can be coupled to both the anchoring component and the locking component ( 815 ) to adjust the distance between the first and second target sites.

First claim

What is claimed is:

1. A cinching apparatus comprising:
an anchoring component having a proximal end and a distal end;
the proximal end of the anchoring component having a first attaching member enabled to piercingly attach to a tissue component of a heart;
a tension member;
a locking component having a second attaching member enabled to piercingly attach to a tissue component of a heart, wherein the locking component is enabled to be locked and unlocked, the locking component comprising a locking system that can be moveably positioned to lock and unlock the tension member in place at any length of a continuous portion of the tension member such that the tension member can be selectively repositioned in both a forward and a reverse direction when the locking component is unlocked;
wherein the anchoring component is enabled to be positioned on a first target site of a tissue component of the heart and the locking component is enabled to be positioned on a second target site of a tissue component of the heart such that the locking component is positioned outside the heart, and the tension member can be coupled to both the anchoring component and the locking component; and
wherein the tension member can be activated to adjust the distance between the first target site and the second target site and fixed by the locking component.

2. The cinching apparatus of claim 1 , wherein the tension member is activated to adjust the distance between the first target site and the second target site by advancing the tension member to reduce the distance between the first target site and the second target site.

3. The cinching apparatus of claim 2 , wherein the tension member is enabled to be unlocked from the locking component, further advanced, and then relocked by the locking component.

4. The cinching apparatus of claim 1 , wherein the first target site is on an anterior mitral annulus and the second target site is on a posterior mitral annulus.

5. The cinching apparatus of claim 4 , wherein the distance between the first target site and the second target site is the septal-lateral diameter.

6. The cinching apparatus of claim 1 , wherein the first target site is on an aortic annulus and the second target site is on an aortic annulus.

7. The cinching apparatus of claim 1 , wherein the first target site and the second target site are located proximate to a sino-tublar junction in an aortic root.

8. The cinching apparatus of claim 1 , wherein the first target site and the second target site are located proximate to a pulmonic valve.

9. The cinching apparatus of claim 1 , wherein the first target site and the second target site are located proximate to a tricuspid valve.

10. The cinching apparatus of claim 1 , wherein the anchoring component is enabled to be delivered endovascularly.

11. The cinching apparatus of claim 1 , wherein the locking component is enabled to be delivered with a long arm device.

12. The cinching apparatus of claim 1 , wherein the tension member is enabled to be advanced from outside of a patient's body.

13. The cinching apparatus of claim 1 , wherein the locking component is enabled to be activated from outside of a patient's body.

14. The cinching apparatus of claim 1 , wherein the locking component is enabled to be activated on an open chest, beating heart.

15. The cinching apparatus of claim 1 , wherein the tension member is a substantially smooth wire.

16. The cinching apparatus of claim 1 , wherein the tension member can be selectively repositioned from outside the body via a remote device.

17. The cinching apparatus of claim 1 , wherein the tension member extends through a long arm device outside of the body.

18. A septal-lateral annular cinching apparatus comprising:
an anchoring component having a proximal end and a distal end;
the proximal end of the anchoring component having a first attaching member enabled to piercingly attach to a tissue component of a heart;
the distal end of the anchoring component having a engaging member;
a tension member with an engaging distal end;
a locking component having a second attaching member enabled to piercingly attach to a tissue component of a heart, wherein the locking component is enabled to be locked and unlocked, the locking component comprising a locking system that can be moveably positioned to lock and unlock the tension member in place such that the tension member can be selectively repositioned in both a forward and a reverse direction when the locking component is unlocked, wherein the tension member is substantially smooth;
wherein the anchoring component is enabled to be positioned on a first target site of a tissue component of the heart and the locking component is enabled to be positioned on a second target site of a tissue component of the heart such that the locking component is positioned outside the heart, the tension member can be passed through the locking component, and the engaging distal end of the tension member can be coupled to the distal end of the anchoring component; and
wherein the tension member can be advanced to reduce the distance between the first target site and the second target site and fixed by the locking component.

19. The septal-lateral annular cinching apparatus of claim 18 , wherein the tension member can be unlocked from the locking component, advanced, and then relocked by the locking component.

20. The septal-lateral annular cinching apparatus of claim 18 , wherein the first and second target sites are located proximate a mitral valve annulus.
