Abstract

A mastopexy implant for maintaining the breast in an elevated and aesthetically pleasing position includes a lower pole support comprising end portions which may be affixed to the chest wall or to a previously installed upper suspension strut. The implant is loaded in an insertion device. The insertion device is inserted through a small incision and into a subcutaneous pocket created in an inferior half of the breast. The lower pole support may have various constructs and in one embodiment includes a unitary conformable mesh having a plurality of arm or band members which are attached across the breast parenchyma and to the chest wall.

First claim

The invention claimed is:

1. An implant for securing a breast of a patient in a lifted position, the implant comprising:
a lower pole support comprising a body having a low-profile configuration, and a self-deploying 3D pre-determined configuration larger than the low-profile configuration, and wherein said 3D pre-determined configuration is sized such that the body substantially spans a lower pole of the breast when deployed; and
a plurality of flexible strap members extending in the upwards direction and lower direction from the body, and wherein said plurality of flexible strap members are integrally formed with said body, wherein the body comprises a material that maintains the 3D pre-determined configuration when unconstrained.

2. The implant of claim 1 wherein the body is a composite of different materials.

3. The implant of claim 2 wherein each of the materials of the body is biodegradable.

4. The implant of claim 3 wherein the body comprises a polymer.

5. The implant of claim 4 wherein the body comprises a porous structure.

6. The implant of claim 1 wherein the body has a canoe-like shape.

7. The implant of claim 1 wherein the body has radius of 4.5 or 5.5 cm.

8. The implant of claim 1 wherein the body has a length of 22 cm.

9. The implant of claim 1 wherein each of the straps has a width between 0.25 to 5 cm.

10. The implant of claim 1 further comprising a plurality of sutures extending through said straps and for securing the straps to supportive tissue, causing the breast to be secured in the lifted position.

11. The implant of claim 1 wherein the plurality of flexible straps comprises more than five straps including at least two upper straps and two lower straps.

12. The implant of claim 1 wherein the body and straps comprises a silk-based material.

13. The implant of claim 1 wherein the body and straps comprises poly-4-hydroxybutyrate (P4HB).

14. The implant of claim 1 wherein at least one of the straps extends in a lateral direction.

15. The implant of claim 1 wherein the straps are extendable.

16. The implant of claim 15 wherein the straps are extendable up to 10%.

17. An implant for securing a breast of a patient in a lifted position, the implant comprising:
a lower pole support comprising a body having a low-profile configuration, and a self-deploying 3D pre-determined configuration larger than the low-profile configuration, and wherein said 3D pre-determined configuration is sized such that the body substantially spans a lower pole of the breast when deployed; and
a plurality of flexible bands extending in the upwards direction and lower direction from the body, and wherein said plurality of flexible bands are integrally formed with said body, wherein the body is comprises of a shape-memory material to provide the 3D pre-determined configuration.

18. The implant of claim 17 wherein the body comprises a canoe-like shape.

19. The implant of claim 17 wherein the plurality of flexible bands comprises more than five bands.

20. The implant of claim 17 wherein the implant is flexible and capable of being rolled cylindrically prior to being deployed.

21. An implant for securing a breast of a patient in a lifted position, the implant comprising:
a lower pole support comprising a body having a low-profile configuration, and a self-deploying 3D pre-determined configuration larger than the low-profile configuration, and wherein said 3D pre-determined configuration is sized such that the body substantially spans a lower pole of the breast when deployed; and wherein the body further comprises a mesh, sheet, fabric, woven construct, knitted construct, braided construct, porous scaffold, nanospun, electrospun, melt-blown construct; and
a plurality of flexible strap members extending in the upwards direction and lower direction from the body, and wherein said plurality of flexible strap members are integrally formed with said body.

22. The implant of claim 1 wherein the low-profile configuration comprises the body in a rolled state.

23. The implant of claim 17 wherein the low-profile configuration comprises the body in a rolled state.
