Abstract

Prosthetic valves implantation methods and systems, especially as related to fitting a prosthetic valve at the site of a native stenotic or incompetent valve are described. The subject devices, systems and associated dock deployment and implant docking techniques may be employed in percutaneous valve replacement procedures.

Claims

1. A medical apparatus, comprising:

a prosthetic valve support structure; and

a docking sleeve configured to interface with the support structure and configured for implantation within a blood vessel of a patient, wherein the docking sleeve comprises an inner sleeve and an outer sleeve, and wherein the docking sleeve further comprises a spring member coupled between the inner sleeve and the outer sleeve.

2. The medical apparatus of claim 1, wherein the docking sleeve comprises a tissue graft.

3. The medical apparatus of claim 1, further comprising:

an elongate member;

an expandable member coupled with the elongate member, the expandable member configured to deploy the docking sleeve.

4. The medical apparatus of claim 1, wherein the docking sleeve is configured to transition from an undeployed state suitable for advancement through the vasculature of a patient to a deployed state.

5. The medical apparatus of claim 1, wherein the docking sleeve is compliant.

6. The medical apparatus of claim 1, further comprising a sealing member configured to seal a space between the inner and outer sleeves.

7. The medical apparatus of claim 1, wherein at least one of the inner sleeve and the outer sleeve comprises a plurality of hinges.

8. The medical apparatus of claim 1, wherein at least one of the inner sleeve and the outer sleeve comprises a plurality of deflectable panels.

9. The medical apparatus of claim 1, wherein the outer sleeve comprises an aperture configured to receive the inner sleeve.

10. The medical apparatus of claim 1, wherein the valve support structure and docking sleeve are each configured to transition from an undeployed state suitable for advancement through the vasculature of a patient to a deployed state.

11. The medical apparatus of claim 10, wherein the docking sleeve is configured to transition from a tri-star configuration.

12. The medical apparatus of claim 1, wherein a plurality of spring members couple the outer sleeve with the inner sleeve.

13. A medical apparatus, comprising:

a prosthetic valve support structure; and

a docking sleeve configured to interface with the support structure and configured for implantation within a blood vessel of a patient, wherein the docking sleeve is coupled to the valve support structure by a plurality of spring members.

14. The medical apparatus of claim 13, wherein the spring members are configured to center the valve support structure.

15. The medical apparatus of claim 13, wherein the docking sleeve is configured to displace the native anatomy.

16. The medical apparatus of claim 13, wherein the docking sleeve is configured to provide a seal with the native anatomy.

17. The medical apparatus of claim 13, wherein the docking sleeve is configured to anchor against the native anatomy.

18. The medical apparatus of claim 13, wherein the docking sleeve comprises a tissue graft.

19. The medical apparatus of claim 13, wherein the docking sleeve has an inner lumen with a regular cross-sectional shape.

20. The medical apparatus of claim 13, further comprising:

an elongate member;

an expandable member coupled with the elongate member, the expandable member configured to deploy the docking sleeve.

21. The medical apparatus of claim 13, wherein the docking sleeve is configured to transition from an undeployed state suitable for advancement through the vasculature of a patient to a deployed state.

22. The medical apparatus of claim 13, wherein the docking sleeve is compliant.

23. The medical apparatus of claim 13, further comprising a sealing member configured to seal a space between the valve support structure and the docking sleeve.

24. The medical apparatus of claim 13, wherein the valve support structure and docking sleeve are each configured to transition from an undeployed state suitable for advancement through the vasculature of a patient to a deployed state.

25. The medical apparatus of claim 24, wherein the docking sleeve is configured to transition from a tri-star configuration.
