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.

Claims

1. A mastopexy system, comprising:

a lower pole support comprising a body region and a plurality of upper and lower straps, and wherein each of said upper and lower straps being a continuous extension and integral with the body region of said lower pole support, and

a first positioning tool comprising a tubular distal section loaded with the lower pole support, wherein the first positioning tool facilitates placement of the lower pole support within a breast through an incision, and wherein the lower pole support holds the breast in place when anchored by the upper and lower straps to a support tissue structure and the body region is around breast parenchyma and wherein the lower pole support is positioned within the tubular distal section of the positioning tool.

2. The mastopexy system of claim 1, wherein the lower pole support has a 3D shape.

3. The mastopexy system of claim 1, wherein the lower pole support is substantially 2 dimensionally shaped.

4. The mastopexy system of claim 1, wherein the lower pole support comprises a mesh material.

5. The mastopexy system of claim 1, wherein the lower pole support is bioabsorbable.

6. The mastopexy system of claim 2, wherein the lower pole support has a canoe shape.

7. A mastopexy system, comprising:

a lower pole support comprising straps, and wherein each of said straps having an aspect ratio of width/thickness in a range of 5/1 and 500/1, and

a first positioning tool comprising a tubular distal section loaded with the lower pole support, wherein the first positioning tool facilitates placement of the lower pole support within a breast through an incision, and wherein the lower pole support holds the breast in place when anchored around breast parenchyma and wherein the lower pole support is positioned around the tubular distal section of the first positioning tool.

8. The mastopexy system of claim 7, wherein the straps are rolled around the first positioning tool.

9. A mastopexy system, comprising:

a lower pole support, said lower pole support comprising a body region and at least one lower strap extending radially from the body region in a lower direction, and at least one upper strap radially extending in an upper direction, and

a first positioning tool comprising a tubular distal section loaded with the lower pole support, wherein the first positioning tool facilitates placement of the lower pole support within a breast through an incision, and wherein the lower pole support holds the breast in place when the at least one lower strap and at least one upper strap are anchored to a supportive structure and the body region is positioned around breast parenchyma, wherein the positioning tool is constructed so as to facilitate placement of the lower pole support through an incision that is less than about 2 cm wide.

10. The mastopexy system of claim 9, wherein the lower pole support comprises a biodegradable material.

11. A mastopexy implant for anchoring a lifted breast of a patient to supportive tissue, the implant comprising:

a flexible lower pole support comprising a body region and a plurality of upper straps and a plurality of lower straps extending from the body region that collectively anchor the lifted breast to the support tissue and wherein at least two of the upper straps extend in an upper and radial direction from the body region.

12. The mastopexy implant of claim 11 wherein the lengths and shapes of the straps facilitate the substantially even distribution of weight of the breast between all straps when the implant is affixed to the support tissue of the patient and lifting the breast.

13. The mastopexy implant of claim 11 wherein at least two of the upper straps are longer than the lower straps.

14. The mastopexy implant of claim 11 wherein at least two of the upper straps are wider than the lower straps.

15. The mastopexy implant of claim 11 wherein at least two upper straps extend in an upward and radial direction from the body forming a concave shape.

16. The mastopexy implant of claim 11 wherein at least two upper straps extend in an upward and radial direction from the body forming a convex shape.

18. The mastopexy implant of claim 11 wherein the two upper straps extend in an upward and radial direction from the body forming a shape selected from the group consisting of a U and V.

19. The mastopexy implant of claim 11 wherein the lower pole support is a sheet and the sheet has a substantially X-shape.

20. The mastopexy implant of claim 11 wherein the plurality of upper straps comprises at least three straps.

21. The mastopexy implant of claim 11 wherein the plurality of lower straps comprises at least three straps.

17. A mastopexy implant for anchoring a lifted breast of a patient to supportive tissue, the implant comprising:

a flexible lower pole support comprising a body region and a plurality of upper straps and a plurality of lower straps extending from the body region that anchors the lifted breast to the support tissue, wherein at least two of the lower straps extend in a downward and radial direction from the body.
