Abstract

A method of biological reconstruction and a device having a major chamber or compartment in the form of the desired anatomy with a shaped chamber inside the main chamber flipped up and held in place by one or more inflatable piston chambers. The inflatable piston chambers selectively hold the shaped chamber and are pressurized in order to support the shape of the device upon implantation. Valves are provided to allow filling the major chamber, the shaped chamber and the piston chambers with a biologically compatible fluid.

Claims

1. A biological prosthesis comprising:

a breast implant comprising a major chamber, the major chamber having a back wall;

a shaped chamber within an upper portion of the major chamber;

at least two piston chambers within the major chamber, the at least two piston chambers configured to flip up and hold the shaped chamber in place within the major chamber; and

a valve associated with each chamber for admitting a biologically compatible fluid into the each chamber with which it is associated.

2. The biological prosthesis of claim 1, wherein the shaped chamber is in the shape of a crescent dome.

3. The biological prosthesis of claim 1, further comprising a easy-to-disconnect filling tube attached to each valve for filling the each chamber, the easy-to-disconnect filling tube removable from the breast implant.

4. The biological prosthesis of claim 1, wherein the breast implant is made of silica.

5. The biological prosthesis of claim 1, wherein the breast implant is made of silicon.

6. The biological prosthesis of claim 1, wherein the at least two piston chambers are attached to an underside of the shaped chamber at a first end of the shaped chamber and attached to the back wall of the major chamber at a point substantially close to a bottom of the back wall to provide upward support to the shaped chamber.

7. The biological prosthesis of claim 6, wherein a second end of the shaped chamber is attached to the back wall of the major chamber at a point substantially close to a top of the back wall.

8. The biological prosthesis of claim 1, wherein the biologically compatible fluid is selected from the group consisting of saline and a soy-based solution.

9. A biological prosthesis for breast reconstruction of a person, the prosthesis comprising:

a breast implant comprising a major chamber, the major chamber having a back wall, the back wall having a top end configured to be positioned in the direction of a head of the person and a bottom end configured to be positioned in the direction of a waist of the person;

a shaped chamber positioned within and towards the top end of the major chamber, the shaped chamber having a first end affixed to the back wall;

at least one piston chamber within the major chamber, the at least one piston chamber configured to flip up and hold the shaped chamber in place within the major chamber, a proximal end of the at least one piston chamber affixed to a second end of the shaped chamber and a distal end of the at least one piston chamber affixed to the back wall substantially near the bottom end; and

a valve associated with each chamber for admitting fluid into the chamber with which it is associated.

10. The biological prosthesis of claim 9, wherein the shaped chamber is in the shape of a crescent dome.

11. The biological prosthesis of claim 9, wherein the breast implant is made of silica.

12. The biological prosthesis of claim 9, wherein the breast implant is made of silicon.

13. The biological prosthesis of claim 9, wherein the biologically compatible fluid is selected from the group consisting of saline and a soy-based solution.

14. A method for breast implantation comprising:

inserting a breast implant through an incision in a breast, the breast implant comprising;

a major chamber having a back wall;

a shaped chamber within an upper portion of the major chamber;

at least two piston chambers within the major chamber, the at least two piston chambers configured to flip up the shaped chamber and support it in place within the major chamber; and

a valve associated with each chamber for admitting a biologically compatible fluid into the each chamber with which it is associated;

positioning the breast implant so the shaped chamber is positioned toward the top portion of the breast;

filling the major chamber and the shaped chamber with the biologically compatible fluid; and

filling the at least two piston chambers with the biologically compatible fluid to flip up the shaped chamber.

15. The method for breast implantation of claim 14, wherein the shaped chamber is in the shape of a crescent dome.

16. The method for breast implantation of claim 14, wherein the breast implant is made of silica.

17. The method for breast implantation of claim 14, wherein the breast implant is made of silicon.

18. The method for breast implantation of claim 14, wherein the at least two piston chambers are attached at one end to an underside of the shaped chamber and attached at a distal end to the back wall of the major chamber at a point substantially close to a bottom of the back wall to provide upward support to the shaped chamber.

19. The method for breast implantation of claim 18, wherein the shaped chamber is attached to the back wall of the major chamber at a point substantially close to a top of the back wall.

20. The method for breast implantation of claim 14, wherein the biologically compatible fluid is selected from the group consisting of saline and a soy-based solution.

21. A biological prosthesis comprising:

a breast implant comprising a major chamber, the major chamber having a back wall;

a shaped chamber within an upper portion of the major chamber, the shaped chamber filled with a biologically compatible fluid;

at least two piston chambers within the major chamber, the at least two piston chambers configured to flip up and hold the shaped chamber in place within the major chamber; and

a valve associated with at least one of the chambers for admitting a second biologically compatible fluid into the at least one of the chambers with which it is associated.

22. The biological prosthesis of claim 21, wherein the shaped chamber is in the shape of a crescent dome.

23. The biological prosthesis of claim 21, further comprising a easy-to-disconnect filling tube attached to each valve for filling the each chamber, the easy-to-disconnect filling tube removable from the breast implant.

24. The biological prosthesis of claim 21, wherein the at least two piston chambers are attached to an underside of the shaped chamber at a first end of the shaped chamber and attached to the back wall of the major chamber at a point substantially close to a bottom of the back wall to provide upward support to the shaped chamber.

25. The biological prosthesis of claim 24, wherein a second end of the shaped chamber is attached to the back wall of the major chamber at a point substantially close to a top of the back wall.

26. The biological prosthesis of claim 21, wherein the biologically compatible fluid and the second biologically compatible fluid is selected from the group consisting of saline and a soy-based solution.
