Abstract

Described herein are breast implant fixation devices for use in breast reconstruction and breast augmentation. Novel wraps are designed to avert lateral displacement and bottoming out of breast implants, reduce capsular contraction and implant extrusion, eliminate skin indentations and ripples caused by breast implants, and reduce or eliminate palpability. The wraps are adapted to securely fold around the breast implants, limiting relative movement between the wrap and breast implant and reducing wrinkles. Tissue in-growth into the wraps limits movement of the wrap-breast implant assembly and thereby limits movement of the breast implant.

First claim

We claim:

1. A breast implant fixation device to secure a breast implant in a patient comprising:
a base section, a cover section, and a hinge region connecting the base section to the cover section;
wherein said implant fixation device comprises a substantially planar two dimensional first configuration; and
a folded three dimensional second configuration comprising a shape and size to at least partially cover the breast implant when the cover section is wrapped around the front of the breast implant and secured to the base section; and
wherein the base section and the cover section each have a plurality of pores, wherein the average diameter of the pores in the cover section is smaller than the average diameter of the pores in the base section, and wherein the cover section has a greater elasticity than the base section.

2. The device of claim 1 , wherein the cover section has an elasticity of 15-75%.

3. The device of claim 1 , wherein the base section has an elasticity of 5-25%.

4. The device of claim 1 , further comprising one or more tabs for anchoring the device to the patient's chest wall to prevent movement of the breast implant.

5. The device of claim 1 , wherein the thickness of the cover section is greater than the thickness of the base section.

6. The device of claim 1 , wherein the base section is formed from a first mesh, and the cover section is formed from a second mesh, and wherein the elasticity of the second mesh is greater than the elasticity of the first mesh.

7. The device of claim 6 , wherein the first and second meshes are formed from fibers and the average diameter of the fibers forming the first mesh is larger than the average diameter of the fibers forming the second mesh.

8. The device of claim 1 , further comprising a plurality of tabs, and a plurality of slits, wherein each slit is adapted to receive one tab such that the cover can be tightened to eliminate wrinkles in the cover.

9. A breast implant wrap comprising:
a thin sheet-like two dimensional first configuration, said first configuration further comprising a base section, a cover section, and a hinge region connecting the base section to the cover section; and
a second three dimensional configuration comprising a shape and size to at least partially cover the breast implant when the cover section is folded around the front of the breast implant and secured to the base section, wherein the cover section has a greater elasticity than the base section.

10. The breast implant wrap of claim 9 , wherein the cover section has a profile selected from the group consisting of: star, flower, and gear.

11. The breast implant wrap of claim 10 , wherein the cover section has a center area and plurality of extension members (or fingers, petals or teeth) radially extending from the center area.

12. The breast implant wrap of claim 11 , wherein the number of extension members ranges from 4 to 8.

13. The breast implant wrap of claim 9 , wherein the base section has a profile selected from the group consisting of: circle, semi-circle, droplet, and ellipse.

14. A method for performing breast implant surgery comprising:
providing a wrap, the wrap comprising a pocket-free, substantially planar first configuration;
placing the breast implant on a base section of the wrap and folding a cover section over the front of the breast implant such that the wrap forms a 3D second configuration enclosing the breast implant, wherein the cover section has a greater elasticity than the base section;
adjusting the tightness of the cover over the top of the breast implant to remove wrinkles and creases across the breast implant;
securing the cover to the base while the cover is stretched; and
locating the wrap containing the breast implant in the breast of a patient.

15. The method of claim 14 , wherein the securing step is performed by interlocking a plurality of radially extending teeth with a plurality slits, each slit being adapted to receive an individual tooth.

16. A breast implant fixation device to secure a breast implant in a patient comprising:
a base section, a cover section, and a hinge region connecting the base section to the cover section;
wherein said implant fixation device comprises a substantially planar two dimensional first configuration; and
a folded three dimensional second configuration comprising a shape and size to at least partially cover the breast implant when the cover section is wrapped around the front of the breast implant and secured to the base section; and
wherein the cover section has a greater elasticity than the base section, and wherein the thickness of the cover section is greater than the thickness of the base section.

17. The device of claim 16 , wherein the cover section has an elasticity of 15-75%.

18. The device of claim 16 , wherein the base section has an elasticity of 5-25%.

19. The device of claim 16 , further comprising one or more tabs for anchoring the device to the patient's chest wall to prevent movement of the breast implant.

20. The device of claim 16 , wherein the base section is formed from a first mesh, and the cover section is formed from a second mesh, and wherein the elasticity of the second mesh is greater than the elasticity of the first mesh.

21. The device of claim 20 , wherein the first and second meshes are formed from fibers and the average diameter of the fibers forming the first mesh is larger than the average diameter of the fibers forming the second mesh.

22. The device of claim 16 , further comprising a plurality of tabs, and a plurality of slits, wherein each slit is adapted to receive one tab such that the cover can be tightened to eliminate wrinkles in the cover.

23. A breast implant fixation device to secure a breast implant in a patient comprising:
a base section, a cover section, and a hinge region connecting the base section to the cover section;
wherein said implant fixation device comprises a substantially planar two dimensional first configuration; and
a folded three dimensional second configuration comprising a shape and size to at least partially cover the breast implant when the cover section is wrapped around the front of the breast implant and secured to the base section; and
wherein the base section is formed from a first mesh, and the cover section is formed from a second mesh, and wherein the elasticity of the second mesh is greater than the elasticity of the first mesh.

24. The device of claim 23 , wherein the cover section has an elasticity of 15-75%.

25. The device of claim 23 , wherein the base section has an elasticity of 5-25%.

26. The device of claim 23 , further comprising one or more tabs for anchoring the device to the patient's chest wall to prevent movement of the breast implant.

27. The device of claim 23 , wherein the first and second meshes are formed from fibers and the average diameter of the fibers forming the first mesh is larger than the average diameter of the fibers forming the second mesh.

28. The device of claim 23 , further comprising a plurality of tabs, and a plurality of slits, wherein each slit is adapted to receive one tab such that the cover can be tightened to eliminate wrinkles in the cover.
