Prosthetic valve implantation systems
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.
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.
