Abstract

A surgically implantable prosthetic device includes a first shell having an exterior surface, an interior surface, and enclosing a lumen, wherein the lumen enclosed by the first shell is able to accommodate a first fluid therein. The prosthetic device further includes a second shell having an exterior surface, an interior surface, and enclosing a lumen, wherein the lumen enclosed by the second shell is able to accommodate a second fluid therein. One or more fitted shells arranged adjacent to and in a graduated relation to each other are situated between the exterior surface of the second shell and the interior surface of the first shell. The one or more shells include an innermost fitted shell and an outermost fitted shell, wherein the innermost fitted shell is adjacent to the exterior surface of the second shell and the outermost fitted shell is adjacent to the interior surface of the first shell.

Claims

1. A surgically implantable prosthetic device, comprising:

a first enclosing shell having an exterior surface, an interior surface, and enclosing a lumen, wherein the lumen enclosed by the first shell is able to accommodate a first fluid therein;

a second enclosing shell having an exterior surface, an interior surface, and enclosing a lumen, wherein the lumen enclosed by the second shell is able to accommodate a second fluid therein; and

one or more non-enclosing fitted shells situated between the exterior surface of the second shell and the interior surface of the first shell such that all surfaces of the fitted shells are in communication with the first fluid.

2. The prosthetic device of claim 1, wherein the one or more fitted shells are adjacent to each other.

3. The prosthetic device of claim 2, wherein the one or more fitted shells comprise an innermost fitted shell and an outermost fitted shell, wherein the innermost fitted shell is adjacent to the exterior surface of the second shell and the outermost fitted shell is adjacent to the interior surface of the first shell.

4. The prosthetic device of claim 2, wherein each fitted shell is generally dome-shaped and has a diameter measurement and a projection measurement, and the projection measurement increases as the diameter measurement increases.

5. The prosthetic device of claim 4, wherein the diameter measurement of one of the fitted shells is greater than the diameter measurement of any other fitted shell.

6. The prosthetic device of claim 5, wherein the fitted shells are arranged in a graduated manner based upon the diameter measurement of each fitted shell, wherein the fitted shell having the smallest diameter measurement is adjacent to the exterior surface of the second shell and wherein the fitted shell having the largest diameter is adjacent to the interior surface of the first shell.

7. The prosthetic device of claim 1, wherein the one or more fitted shells include at least one or more holes.

8. The prosthetic device of claim 1, wherein the one or more fitted shells include at least one perforation.

9. The prosthetic device of claim 1, wherein at least one of the first shell, the second shell, and the fitted shells are constructed of a biocompatible material.

10. The prosthetic device of claim 1, wherein at least one of the first shell and the second shell are constructed of a nonporous material.

11. The prosthetic device of claim 1, wherein the distance between each of the one or more fitted shells is between 0 cm and 1.0 cm.

12. The prosthetic device of claim 1, wherein the lumen enclosed by the first shell is filled with the first fluid.

13. The prosthetic device of claim 12, wherein the first shell includes a first valve for allowing for the filling of the lumen enclosed by the first shell with the first fluid.

14. The prosthetic device of claim 1, wherein the lumen enclosed by the second shell is filled with the second fluid.

15. The prosthetic device of claim 14, wherein the second shell includes a second valve for allowing for the filling of the lumen enclosed by the second shell with the second fluid.

16. The prosthetic device of claim 1, wherein the first fluid is able to envelop at least the one or more fitted shells.

17. The prosthetic device of claim 1, wherein the first fluid and the second fluid are at least one of an organic solution and a synthetic solution.

18. The prosthetic device of claim 1, wherein the first fluid and the second fluid are at least one of an electrolyte solution and a saline solution.

19. The prosthetic device of claim 18, wherein at least one of the first fluid and the second fluid further comprises a lubricating agent.

20. The prosthetic device of claim 1, wherein the device is a breast implant.
