Abstract

The systems and devices and methods relate to surgical and percutaneous repair of heart valve regions. The systems and devices are structured to conform to the desired shape of a specific patient. The devices may include a mounting structure and a valve support onto which leaflets of the valve may coapt or rest. The devices may be structured to be mounted directly onto a leaflet of the valve.

Claims

1. A device structured to be implanted to repair a valve, comprising:

at least one valve support structured to expand when filled with a fluid and/or a gas; and

at least one receiving member extending from the at least one valve support, the at least one receiving member being structured to receive and deliver the fluid and/or the gas to the at least one valve support.

3. The device according to claim 1, wherein the at least one valve support includes a balloon.

4. The device according to claim 1, wherein the at least one valve support includes a permeable membrane.

5. The device according to claim 1, wherein the device includes more than one valve support.

9. The device according to claim 1, further comprising:

a mounting structure structured to be disposed on a surface of a leaflet, wherein the at least one valve support is disposed on the mounting structure.

21. The device according to claim 1, wherein the at least one valve support is structured to be disposed on a surface of a leaflet.

22. The device according to claim 1, wherein the device includes two receiving members extending from the at least one valve support.

23. The device according to claim 5, wherein a first valve support is structured to be disposed on an atrial surface of a leaflet of a valve, and a second valve support is structured to be disposed on a ventricular surface of the leaflet.

24. The device according to claim 23, wherein the first valve support and the second valve support are separated by a gap.

25. The device according to claim 1, wherein the at least one receiving member is integrated with the at least one valve support.

12. A device for repairing a valve, comprising:

at least one valve support structured to expand when filled with a fluid and/or a gas;

and

at least one connector that extends from the at least one valve support to a port and is structured to deliver the fluid and/or the gas to the at least one valve support.

13. The device according to claim 12, wherein the port is structured to be inserted at the ventricular apex.

14. The device according to claim 12, wherein:

the connector includes a

hollow tube that extends from the at least one valve support to a port and is structured to deliver the fluid and/or the gas to expand the at least one valve support; and

wherein the hollow tube includes a valve structured for an injection of the fluid and/or the gas.

17. The device according to claim 12, wherein the at least one valve support is structured to provide a coaptation surface for a valve leaflet.

26. The device according to claim 12, wherein the device includes two connectors, each connector including a hollow tube that extends from the at least one valve support to the port and is structured to deliver the fluid and/or the gas to expand the at least one valve support.

27. The device according to claim 12, wherein the device includes a first valve support is structured to be disposed on an atrial surface of a leaflet of a valve, and a second valve support is structured to be disposed on a ventricular surface of the leaflet.

28. The device according to claim 12, wherein the connector includes two lumens.

29. The device according to claim 12, wherein the at least one valve support is structured to be disposed on a surface of a leaflet.

15. (canceled)

16. (canceled)

18. A device for repairing a valve, comprising:

at least two valve supports structured to expand when filled with a fluid and/or a gas, at least one valve support being disposed on an atrial side and a ventricular side of a leaflet; and

at least two mounting structures structured to be directly disposed on a surface of a leaflet.

20. The device according to claim 18, further comprising:

at least one connector extending from the at least two valve supports and configured to anchor the at least two valve supports with respect to a cardiac access point and deliver the fluid and/or the gas to the at least two valve supports.
