Abstract

The present invention relates to an anchoring device (1) designed for anchoring a prosthetic heart valve inside a heart, comprising an extraventricular part (2) designed to be positioned inside an atrium or an artery and a ventricular part (3) designed to be positioned inside a ventricle, wherein the ventricular part comprises a double wall composed of an outer wall (4) and an inner wall (5) spaced apart at the level where the prosthetic heart valve is intended to be inserted, and wherein the anchoring device further comprises a predefined V-shaped groove (8) formed between the extraventricular part (2) and the ventricular part (3). The present invention also relates to an anchoring system (11) for anchoring a prosthetic heart valve inside a heart, comprising said anchoring device (1), a prosthetic heart valve support (12) and a prosthetic heart valve (13) connected to the prosthetic heart valve support (12).

Claims

1. A system for treating heart valve disease, comprising:

a prosthetic heart valve support,

a prosthetic heart valve mounted in the prosthetic heart valve support, and

an expandable anchoring device for positioning the prosthetic heart valve inside a heart,

wherein the anchoring device comprises a double wall made of a flexible braided mesh and a groove for accommodating the native valve, the groove allowing the anchoring device to be self-positioning.

2. The system of claim 1, wherein the prosthetic heart valve support exhibits a higher stiffness than the anchoring device.

3. The system of claim 1, wherein the braided mesh comprises a continuous mesh.

4. The system of claim 1, wherein the prosthetic heart valve support is securely attached to the anchoring device.

5. The system of claim 4, wherein the prosthetic heart valve support is sutured to the anchoring device.

6. The system of claim, 1 wherein the anchoring device is configured for anchoring a tricuspid valve.

7. The system of claim 1, wherein the anchoring device is configured to pinch the sub- and supra-annular surfaces without exerting radial force on the annulus.

8. The system of claim 1, wherein the double wall extends substantially along the entire length of the system.

9. The system of claim 1, wherein the double wall comprises an inner wall and an outer wall, the inner wall being spaced apart from the outer wall.

10. The system of claim 9, wherein the inner wall is configured for placement inside a ventricle, and the outer wall is configured for placement inside an artery or atrium of the heart.

11. The system of claim 10, wherein the inner wall is substantially cylindrical, and the outer wall is substantially conical, the substantially conical outer wall being connected to the substantially cylindrical inner wall at its larger diameter end.

12. The system of claim 1, wherein the groove is V- or U-shaped.

13. The system of claim 1, wherein the heart valve support has a constant cross-section along its length.

14. The system of claim 1, further including at least one extraventricular flange.

15. The system of claim 1, further including a plurality of arms for securing the anchoring device to native heart tissue.

16. The system of claim 1, further including a cover at least partially covering the anchoring device.

17. The system of claim 1, further comprising a tie or a suture for releasably connecting and re-connecting the anchoring device to a catheter during or after implantation of the anchoring device.

18. The system of claim 17, wherein the tie or suture is configured to pass through at least a portion of the braided mesh of the anchoring device.

19. A method of treating heart valve disease, comprising:

providing a system comprising a prosthetic heart valve support, a prosthetic heart valve mounted in the prosthetic heart valve support, and an expandable anchoring device, wherein the anchoring device comprises a double wall made of a flexible braided mesh and a groove for accommodating the native valve, the groove allowing the anchoring device to be self-positioning; and

positioning the system such that the groove resides between the ventricle and the atrium or artery.

20. The method of claim 19, wherein the prosthetic heart valve is a tricuspid heart valve.

21. The method of claim 19, further including the step of anchoring the system to the native heart tissue.
