Abstract

Inflatable multi-chambered devices are provided for repairing or replacing spinal discs and distracting neighboring vertebral elements. Also included are cushioning devices that may be used in a joint replacement device cushioning system. Further included are kits and systems that include such devices, methods for making such devices, and methods of treating patients in need of such devices. Examples further include cosmetic augmentation and restoration devices.

First claim

What is claimed is:

1. A surgical method comprising:
inserting a multi-chambered inflatable implant into a disc space of a patient in a deflated configuration, the multi-chambered inflatable implant having chambers and a single filling manifold having a plurality of holes and a rotatable valve, each of the plurality of holes being aligned with a corresponding opening in a respective one of the chambers;
rotating the rotatable valve such that a first subset of the plurality of holes fluidly couples the single filling manifold with a first subset of the chambers;
inflating the first subset of the chambers of the multi-chambered implant by using the single filling manifold to fill the first subset of the chambers within the disc space of the patient;
rotating the rotatable valve such that a second subset of the plurality of holes fluidly couples the single filling manifold with a second subset of the chambers; and
inflating the second subset of the chambers of the multi-chambered implant by using the single filling manifold to fill the second subset of the chambers within the disc space of the patient to form an inflated implant,
wherein the implant includes a pressure detector configured to detect pressure within at least one of the chambers.

2. The method of claim 1 , wherein the implant is inflated until a filling end point is reached based on a pressure reading from the pressure detector.

3. The method of claim 1 , wherein the pressure detector transmits a signal to a remote device to indicate when the chambers have been filled to a desired amount.

4. The method of claim 1 , wherein the inflation stops automatically upon a pressure range reaching a pre-set level.

5. The method of claim 1 , wherein the pressure detector is positioned within at least one of the chambers.

6. The method of claim 1 , wherein the chambers are sealed after inflation to prevent leakage of filling material out of the chambers.

7. The method of claim 1 , wherein the chambers are independent chambers in which filling material does not pass therebetween.

8. The method of claim 1 , wherein the chambers are interrelated chambers in which filling material passes therebetween.

9. The method of claim 1 , wherein the implant comprises three chambers, a first chamber positioned inside a second chamber, and the second chamber positioned inside a third chamber.

10. The method of claim 1 , wherein the filling manifold has a rotating ball valve.

11. The method of claim 1 , wherein the chambers are formed of a flexible polymer.

12. The method of claim 1 , wherein the chambers are inflated with a filling material selected from the group consisting of hydrogel, air, water, and saline.

13. The method of claim 1 , wherein the chambers are inflated with a filling material comprising a non-resorbable hydrogel.

14. A surgical method comprising:
inserting a multi-chambered inflatable implant into a disc space of a patient in a deflated configuration, the multi-chambered inflatable implant having chambers and a single filling manifold having a plurality of holes and a rotatable valve, each of the plurality of holes being aligned with a corresponding opening in a respective one of the chambers;
rotating the rotatable valve such that a first subset of the plurality of holes fluidly couples the single filling manifold with a first subset of the chambers;
adding a filling material into the single filling manifold of the implant to inflate the first subset of the chambers of the multi-chambered implant within the disc space of the patient;
rotating the rotatable valve such that a second subset of the plurality of holes fluidly couples the single filling manifold with a second subset of the chambers;
adding the filling material into the single filling manifold of the implant to inflate the second subset of the chambers of the multi-chambered implant within the disc space of the patient to form an inflated implant, wherein the implant includes a pressure detector configured to detect pressure within at least one of the chambers; and
upon reaching a desired pressure, sealing the implant to prevent the filling material from entering or exiting one or more of the chambers.

15. The method of claim 14 , wherein the filling material is added until a filling end point is reached based on a pressure reading from the pressure detector.

16. The method of claim 14 , wherein the pressure detector transmits a signal to a remote device to indicate when the chambers have been filled to a desired amount.

17. The method of claim 14 , wherein the inflation stops automatically upon a pressure range reaching a pre-set level.

18. The method of claim 14 , wherein the pressure detector is positioned within at least one of the chambers.

19. The method of claim 14 , wherein the chambers are independent chambers in which filling material does not pass therebetween.

20. The method of claim 14 , wherein the implant comprises three chambers, a first chamber positioned inside a second chamber, and the second chamber positioned inside a third chamber.
