Abstract

Devices, systems, and methods associated with annuloplasty are described herein. One or more annuloplasty devices include a number of longitudinal filaments moveable between an introductory configuration and a deployed configuration, wherein the number of longitudinal filaments are one or more lengths, and a shell, wherein the shell contains the number of longitudinal filaments and a curable polymer to maintain the annuloplasty device in a deployed configuration.

Claims

1. An annuloplasty device, comprising:

a number of longitudinal filaments moveable between an introductory configuration and a deployed configuration, wherein the number of longitudinal filaments are one or more lengths;

a shell, wherein the shell contains the number of longitudinal filaments and a curable polymer to maintain the annuloplasty device in a deployed configuration; and

a number of valves to introduce fluid into the shell to form the shape of the device.

2. The device of claim 1, wherein strengthening additives are included in the polymer.

3. The device of claim 1, wherein attachment mechanisms are included on an outer surface of the shell.

4. The device of claim 1, wherein the number of longitudinal filaments are made of nitinol.

5. The device of claim 1, wherein the number of longitudinal filaments form a pattern within the shell.

6. The device of claim 1, wherein the number of longitudinal filaments and the shell are formed to fit proximate a mitral annulus.

7. The device of claim 1, wherein at least one of the number of longitudinal filaments are coupled to the shell.

8. The device of claim 1, wherein the device includes an opening to introduce a shaping tool to the device.

9. An annuloplasty device delivery system, comprising:

an annuloplasty device, wherein the annuloplasty device includes a number of longitudinal filaments within a shell; and

a delivery device, wherein the delivery device includes a first lumen to introduce a contrast fluid and/or a curable polymer into the annuloplasty device and the delivery device is coupled to the annuloplasty device with a coupling mechanism and configured to position the annuloplasty device proximate to a mitral annulus and transition the annuloplasty device from an introductory configuration to a deployed configuration.

10. The system of claim 9, wherein the delivery device includes a second lumen to remove a saline and/or contrast fluid from the annuloplasty device.

11. The system of claim 9, wherein the coupling mechanism is a detachable coupling mechanism and the delivery device is configured for detachment from the annuloplasty device when the annuloplasty device is placed proximate to the mitral annulus in the deployed configuration.

12. The system of claim 9, wherein the delivery device includes a third lumen to introduce a shaping tool to the annuloplasty device.

13. An annuloplasty device, comprising:

a number of longitudinal filaments moveable between an introductory configuration and a deployed configuration, wherein the number of longitudinal filaments are one or more lengths;

a shell, wherein the shell contains the number of longitudinal filaments and a curable polymer to maintain the annuloplasty device in a deployed configuration; and

an opening to introduce a shaping tool to the device.
