The teachings, expressions, embodiments, examples, etc. described herein should not be viewed in isolation relative to each other. Various suitable ways in which the teachings herein may be combined should be readily apparent to those of ordinary skill in the art in view of the teachings herein.

[0051] Having shown and described exemplary embodiments of the subject matter contained herein, further adaptations of the methods and systems described herein may be accomplished by appropriate modifications without departing from the scope of the claims. Some such modifications should be apparent to those skilled in the art. For instance, the examples, embodiments, geometries, materials, dimensions, ratios, steps, and the like discussed above are illustrative. Accordingly, the claims should not be limited to the specific details of structure and operation set forth in the written description and drawings.

We claim:

1. An adjustable implant, comprising:

a shell including a base and having a first diameter in a plane parallel to the base, the shell further including a first membrane,

a hydraulic mechanism disposed within the shell, the mechanism including a first component and a second component that is moveable with respect to the first component; and a band disposed within the shell in a round configuration having a second diameter in the plane that is less than the first diameter, the band having a first end and a second end,

wherein the first end of the band is connected to the first component and the second end of the band is connected to the second component.

2. The adjustable implant of claim 1, wherein the mechanism includes a fluid and a pump having a first actuator comprising a first chamber and a second actuator comprising a second chamber.

3. The adjustable implant of claim 2, wherein the first component is a barrel and the second component is a piston disposed at least partially within the barrel, and wherein the piston further includes a plunger rod and a plunger cap and the barrel further includes a barrel cap, a first port, and a second port.

4. The adjustable implant of claim 3, wherein the mechanism further includes a first tube connected between the first chamber and the first port and a second tube connected between the second port and the second chamber.

5. The adjustable implant of claim 4, further comprising a loop through which the band is disposed.

6. The adjustable implant of claim 5 wherein the loop is attached to the first membrane.

7. The adjustable implant of claim 6, wherein the shell further comprises a second membrane surrounding the first membrane.

8. The adjustable implant of claim 7, wherein the mechanism further includes a biasing member in the barrel between the piston and the barrel cap, and a bladder connecting the first chamber to the second chamber.

9. The adjustable implant of claim 8, wherein the second actuator includes a finger for opening a valve disposed in the second tube.

10. The adjustable implant of claim 9, wherein the round configuration is an elliptical configuration.

11. An adjustable implant, comprising:

a shell including a first membrane filled with an elastomer;

a hydraulic mechanism disposed within the shell, the mechanism including a pump, a piston, and a barrel; and

an adjustable band disposed within the shell in a round configuration having a first end connected to the barrel and a second end connected to the piston.

12. The adjustable implant of claim 11, further comprising a loop through which the band is disposed.

13. The adjustable implant of claim 12 wherein the loop is attached to the first membrane.

14. The adjustable implant of claim 13, wherein the shell further comprises a second membrane surrounding the first membrane.

15. A method of using an adjustable implant, comprising:

providing an implant having a height and including therein an adjustable band having a round configuration and a diameter;

decreasing the diameter of the band; and

increasing the height of the implant.

16. The method of claim 15, further comprising:

increasing the diameter of the band; and

decreasing the height of the implant.

17. The method of claim 16, wherein

the implant includes

a shell including a base and having a first diameter in a plane parallel to the base, the shell further including a first membrane;

a hydraulic mechanism disposed within the shell, the mechanism including

a barrel having a barrel cap, a first port, and a second port, and a piston at least partially disposed within the barrel including a plunger rod and plunger cap, a fluid,

a pump having a first actuator including a first chamber and a second actuator including a second chamber; and

wherein the band includes a first end connected to the barrel cap and a second end connected to the plunger cap.

18. The method of claim 17, further comprising

depressing the first actuator; and

depressing the second actuator.

19. The method of claim 18, wherein depressing the first actuator advances fluid into the barrel and causes the piston, plunger cap, and the second end of the band to move in a first direction.

20. The method of claim 19, wherein depressing the second actuator causes the piston, plunger cap, and the second end of the band to move in a direction opposite the first direction.
