Abstract

A prosthetic heart valve in combination with a delivery assembly that includes a first elongate component that is movably disposed to a second elongate component. The delivery assembly has a temporary valve location relative to the delivery assembly to which the prosthetic heart valve can be releasably mounted in position and a spaced implantation location relative to the delivery assembly to which the prosthetic heart valve can also be releasably mounted in position. The prosthetic heart valve and delivery assembly combination is configurable with movement of the first elongate component relative to the second elongate component from a delivery state with the prosthetic heart valve mounted in the temporary location to an implantation state with the prosthetic heart valve repositioned from the temporary, location to the implantation location so that the prosthetic heart valve can subsequently be deployed from the implantation location.

Claims

1. A prosthetic heart valve in combination with a delivery assembly, the delivery assembly comprising:

a first elongate component that is movably disposed to a second elongate component,

the delivery assembly having a temporary valve location relative to the delivery assembly to which the prosthetic heart valve can be releasably mounted in position and a spaced implantation location relative to the delivery assembly to which the prosthetic heart valve can also be releasably mounted in position,

the prosthetic heart valve and delivery assembly combination being configurable with movement of the first elongate component relative to the second elongate component from a delivery state with the prosthetic heart valve mounted to the temporary location to an implantation state with the prosthetic heart valve repositioned from the temporary location to the implantation location so that the prosthetic heart valve can subsequently be deployed from the implantation location,

wherein the first elongate component is configured to deploy the prosthetic heart valve at a fixation site, and wherein the second elongate component is configured to apply an axial force to the prosthetic heart valve in a direction of advancement.

2. The combination of claim 1, wherein the prosthetic heart valve is a replacement aortic valve.

3. The combination of claim 1, wherein the prosthetic heart valve comprises tissue leaflets.

4. The combination of claim 1, wherein the prosthetic heart valve is a replacement mitral valve.

5. The combination of claim 1, wherein the prosthetic heart valve is a replacement pulmonic valve.

6. The combination of claim 1, wherein the prosthetic heart valve is a replacement tricuspid valve.

7. The combination of claim 1, wherein a distal portion of the first elongate component is articulable, and wherein a distal portion of the second elongate component is articulable.

8. A delivery assembly having a temporary valve location to which a prosthetic heart valve can be releasably mounted in position and a spaced implantation location to which the prosthetic heart valve can also be releasably mounted in position, the delivery assembly comprising:

a first elongate component; and

a second elongate component,

wherein the first elongate component is configured to move relative to the second elongate component from a delivery state with the prosthetic heart valve mounted at the temporary location to an implantation state with the prosthetic heart valve repositioned from the temporary location to the implantation location such that the prosthetic heart valve can subsequently be deployed from the implantation location, and

wherein the first elongate component is configured to deploy the prosthetic heart valve at a fixation site, and wherein the second elongate component is configured to apply an axial force to the prosthetic heart valve in a direction of advancement.

9. The delivery assembly of claim 8, wherein the prosthetic heart valve is a replacement aortic valve.

10. The delivery assembly of claim 8, wherein a distal portion of the first elongate component is articulable, and wherein a distal portion of the second elongate component is articulable.

11. A prosthetic heart valve in combination with a delivery assembly, the delivery assembly comprising:

a first elongate component that is movably disposed to a second elongate component,

the first elongate component having a temporary valve location to which the prosthetic heart valve can be releasably mounted, and the second elongate component having a spaced implantation location to which the prosthetic heart valve can also be releasably mounted,

the prosthetic heart valve and delivery assembly combination being configurable with movement of the first elongate component relative to the second elongate component from a delivery state with the prosthetic heart valve mounted to the temporary location to an implantation state with the prosthetic heart valve repositioned from the temporary location to the implantation location so that the prosthetic heart valve can subsequently be deployed from the implantation location.

12. The combination of claim 11, wherein the first elongate component is a catheter.

13. The combination of claim 11, wherein the second elongate component is a catheter.

14. The combination of claim 11, wherein the prosthetic heart valve is a replacement aortic valve.

15. The combination of claim 11, wherein a distal portion of the first elongate component is articulable, and wherein a distal portion of the second elongate component is articulable.
