Abstract

Prosthetic ring valve assemblies are disclosed. A prosthetic valve ring assembly includes an outer tube and a plurality of anchors. The outer tube includes a plurality of windows. The plurality of anchors are positioned inside the outer tube and about a perimeter of the outer tube. The plurality of anchors are configured to be emitted from the plurality of windows in order to anchor the prosthetic valve ring assembly to annulus tissue of a patient.

Claims (33)

1. A prosthetic valve ring assembly, comprising:

an outer tube comprising a plurality of windows;

a plurality of anchors positioned inside the outer tube and around a perimeter of the outer tube, wherein the plurality of anchors are configured to be emitted from the plurality of windows to anchor the prosthetic valve ring assembly to a patient's annulus tissue;

a closure device configured to lock a distal end and a proximal end of the prosthetic valve ring assembly; and

an unsnapping pin configured to unlock the closure device to separate the distal end and the proximal end of the prosthetic valve ring assembly, thereby providing for repositioning or retrieval of the prosthetic valve ring assembly from the patient through a catheter.

2. The prosthetic valve ring assembly of claim 1 , wherein a first portion of the plurality of anchors is configured to be emitted to an atrial side of the annulus tissue in an outward and upward direction relative to a plane of the outer tube, and a second portion of the plurality of anchors is configured to be emitted to a ventricular side of the annulus tissue in an outward and downward direction relative to the plane of the outer tube.

3. The prosthetic valve ring assembly of claim 1 , wherein the plurality of anchors are created using a laser cutting technique.

4. The prosthetic valve ring assembly of claim 3 , wherein the laser cutting technique comprises cutting according to a laser cut pattern to define the plurality of windows through which the plurality of anchors are configured to be emitted.

5. The prosthetic valve ring assembly of claim 1 , further comprising a post adjustment mechanism comprising a flexible connection configured to move an anterior portion of the outer tube relative to a posterior portion of the outer tube, thereby changing at least one of a size and a geometry of the outer tube.

6. The prosthetic valve ring assembly of claim 5 , wherein the post adjustment mechanism comprises a first adjustable component that couples the anterior portion of the outer tube to the posterior portion of the outer tube, and

wherein the first adjustable component is configured to expand and contract.

7. The prosthetic valve ring assembly of claim 6 , wherein the post adjustment mechanism further comprise a second adjustable component that couples the anterior portion of the outer tube to the posterior portion of the outer tube,

wherein the first adjustable component and the second adjustable component are disposed on opposing lateral side of the outer tube, and

wherein the first adjustable component and the second adjustable component are configured to expand and contract.

8. The prosthetic valve ring assembly of claim 6 , wherein the first adjustable component is fabricated from a flexible material.

9. The prosthetic valve ring assembly of claim 5 , wherein the post adjustment mechanism comprising a ratcheting feature that is configured to change the size and geometry of the prosthetic valve ring assembly.

10. The prosthetic valve ring assembly of claim 1 , further comprising one or more bumps positioned on the perimeter of the outer tube and configured to apply additional pressure to trigones of the patient's annulus tissue, thereby providing improved anchoring of the prosthetic valve ring assembly.

11. The prosthetic valve ring assembly of claim 1 , further comprising a first bump positioned on the perimeter on an anterior portion of the outer tube and a second bump positioned on the perimeter on the anterior portion of the outer tube, wherein the first bump is positioned on an opposite lateral side as the second bump.

12. The prosthetic valve ring assembly of claim 1 , wherein the closure device is interfaced to the outer tube by pins which are configured to function as pulleys for sutures.

13. The prosthetic valve ring assembly of claim 1 , wherein an anterior portion of the prosthetic valve ring assembly comprises a cutout that extends from an outer surface of the outer tube toward an interior of the outer tube.

14. The prosthetic valve ring assembly of claim 1 , further comprising a plurality of second anchors,

wherein each anchor of the plurality of anchors has a first shape and each second anchor of the plurality of second anchors has a second shape different than the first shape.

15. The prosthetic valve ring assembly of claim 14 , wherein each second anchor of the plurality of second anchors is positioned adjacent the closure device.

16. The prosthetic valve ring assembly of claim 14 , wherein the plurality of second anchors comprises a first anchor and a second anchor.

17. The prosthetic valve ring assembly of claim 16 , wherein the first anchor is oriented in a first direction and a second anchor oriented in a second direction different than the first direction.

18. The prosthetic valve ring assembly of claim 17 , wherein the first direction is oriented towards the second anchor and the second direction is oriented towards the first anchor.

19. The prosthetic valve ring assembly of claim 16 , wherein the first anchor is oriented at a first angle and the second anchor oriented at a second angle different than the first angle.

20. The prosthetic valve ring assembly of claim 16 , wherein the first anchor is disposed on the distal end of the prosthetic valve ring assembly and the second anchor is disposed on the proximal end of the prosthetic valve ring assembly.

21. The prosthetic valve ring assembly of claim 14 , wherein each second anchor of the plurality of second anchors comprises a free end configured to engage the patient's posterior annulus tissue.

22. The prosthetic valve ring assembly of claim 14 , wherein each second anchor of the plurality of second anchors is configured to be emitted from the plurality of windows.

23. The prosthetic valve ring assembly of claim 14 , wherein one or more second anchor of the plurality of second anchors is configured to be emitted to a ventricular side of the patient's annulus tissue.

24. The prosthetic valve ring assembly of claim 14 , wherein one or more second anchor of the plurality of second anchors is configured to be emitted to an atrial side of the patient's annulus tissue.

25. The prosthetic valve ring assembly of claim 14 , wherein each second anchor of the plurality of second anchors comprises one or more of a hook or a barb.
