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:

a plurality of valve supports structured to expand;

at least one receiving member extending from the valve supports to a port, the at least one receiving member being structured to expand the valve supports; and

at least one mounting structure structured to be disposed on a surface of a leaflet,

wherein at least one of the valve supports is disposed on the at least one mounting structure.

2. The device according to claim 1, wherein:

the plurality of supports are structured to expand when filled with fluid and/or gas;

the at least one receiving member is structured to receive and deliver the fluid and/or gas to the valve supports; and

the valve supports includes a balloon and/or a permeable membrane.

9. The device according to claim 1, wherein the device includes two receiving members extending from the valve supports.

10. The device according to claim 1, wherein the valve supports includes a first valve support structured to be disposed on an atrial surface of a leaflet of a valve, and a second valve support structured to be disposed on a ventricular surface of the leaflet.

11. The device according to claim 10, wherein the first valve support and the second valve support are separated by a gap.

12. The device according to claim 1, wherein the at least one receiving member is integrated with the supports.

3. A device for repairing a valve, comprising:

a plurality of valve supports that are structured to expand, the valve supports including a first valve support that is structured to be disposed on an atrial surface of a leaflet of a valve and a second valve support that is structured to be disposed on a ventricular surface of the leaflet; and

at least one connector that extends from the valve supports to a port and is structured to expand the valve supports,

wherein the at least one connector includes two lumens.

4. The device according to claim 3, wherein:

the valve supports are structured to expand when filled with a fluid and/or a gas;

the at least one connector is structured to deliver the fluid and/or the gas to the valve supports; and

the port is structured to be inserted at a ventricular apex.

5. The device according to claim 4, wherein:

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

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

6. The device according to claim 3, wherein at least one of the valve supports is structured to provide a coaptation surface for a valve leaflet.

13. The device according to claim 3, wherein the device includes two connectors, each connector extends from the valve supports to the port and is structured to expand the valve supports.

7. A device for repairing a valve, comprising:

at least two opposing mounting structures, the at least two opposing mounting structures including a first mounting structure and a second mounting structure separated by a gap;

a plurality of valve supports structured to expand, the plurality of valve supports including a first valve support disposed on a surface of the first mounting structure and a second valve support mounted on a surface of the second mounting structure; and

at least one connector extending from the valve supports and configured to expand each of the valve supports.

8. The device according to claim 7, further comprising:

a port configured to be disposed in a cardiac access point,

wherein the at least one connector is configured to connect to the port to anchor the valve supports with respect to the cardiac access point.

14. A device for repairing a valve, comprising:

at least one mounting structure structured to be disposed on a surface of a leaflet;

a plurality of valve supports disposed on the at least one mounting structure and structured to expand;

a port configured to be disposed at a cardiac access point; and

at least one connector that extends from the valve supports to the port and is structured to expand the at least one valve support.

15. The device according to claim 14, wherein the port is structured to be inserted at a ventricular apex.

16. The device according to claim 14, wherein:

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

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

17. The device according to claim 14, wherein the device includes two connectors, each connector extending from the valve supports to the port and is structured to expand the at least one valve support.

18. The device according to claim 14, wherein the device includes a first valve support that is structured to be disposed on an atrial surface of a leaflet of a valve, and a second valve support that is structured to be disposed on a ventricular surface of the leaflet.

19. The device according to claim 14, wherein each mounting structure has an elongated shape.
