Abstract

A valve such as an esophageal valve (1) has a normally closed configuration in which the valve (1) is closed and an open configuration in which the valve (1) is opened for flow through the valve (1). A support (102) for the valve (1) is adapted for mounting to a pre-deployed luminal prosthesis (140) intermediate a proximal end and a distal end of the predeployed luminal prosthesis (140).

Claims

1. A valve having:

—

a normally closed configuration in which the valve is closed;

an open configuration in which the valve is opened for flow through the valve; and

a support for the valve, the support being adapted for mounting to a pre-deployed luminal prosthesis intermediate a proximal end and a distal end of the pre-deployed luminal prosthesis.

2. A valve as claimed in claim 1, wherein the luminal prosthesis comprises a stent or an esophageal stent.

4. A valve as claimed in claim 1, wherein the valve support comprises a support structure.

5. A valve as claimed in claim 4, wherein the support structure-tapers outwardly or inwardly, the support structure having a generally uniform diameter along the length thereof.

8. A valve as claimed in claim 4, wherein the support structure comprises a scaffold or a stent-like structure.

10. A valve as claimed in claim 4 comprising mounting means for mounting the valve support to a pre-deployed luminal prosthesis.

12. A valve as claimed in claim 10, wherein the mounting means is provided by the support structure, the mounting means comprising protrusions extending from the support structure.

13. A valve as claimed in claim 12 wherein the protrusions extend from the support structure adjacent to a proximal end of the support structure.

14. A valve as claimed in claim 12, wherein the protrusions extend from the support structure adjacent to a distal end of the support structure or from the support structure intermediate a proximal end and a distal end of the support structure.

16. A valve as claimed in claim 12 wherein the protrusions are adapted to engage with a pre-deployed host support.

17. A valve as claimed in claim 12, wherein the protrusion comprises a loop or wherein the apicial tip of the protrusion is rounded.

20. A valve as claimed in claim 12 comprising release means for releasing the valve from engagement with a pre-deployed host support.

21. A valve as claimed in claim 20, wherein the release means comprises means for reducing the diameter of at least a portion of the valve support structure or a drawstring extending around the valve support structure.

25. A valve as claimed in claim 4 wherein the valve is mounted to the support structure.

26. A valve as claimed in claim 1 wherein the valve is an esophageal valve for mounting to an esophageal stent.

27. A valve device comprising a valve as claimed in claim 1 and a luminal prosthesis.

28. A method for providing a valve in a body passageway comprising the steps of:

—

providing a valve mounted to a support structure;

delivering the valve mounted to the support structure to a pre-deployed luminal prosthesis in the body passageway; and

deploying the valve so that the valve is mounted to the luminal prosthesis.

29. A method as claimed in claim 28 wherein the step of deploying the valve comprises engaging the valve support with the pre-deployed luminal prosthesis.

30. A method as claimed in claim 29, further comprising the step of releasing the valve support from engagement with the luminal prosthesis, or further comprising repositioning the valve support within the prosthesis, or further comprising removing the valve from the prosthesis.

33. A method as claimed in claim 28 wherein the body passageway is the esophagus and the valve is an esophageal valve for mounting to a pre-deployed esophageal stent.
