Abstract

A soft breast prosthesis is provided, the prosthesis having a surface configuration advantageous for dual plane placement of the prosthesis in a breast.

Claims

1. A breast prosthesis comprising:

an implantable member including an exterior defined by a lower pole region defined by a first texture and an upper pole region defined by a second texture different from the first texture;

wherein the first texture is an open cell textured surface; and

wherein the second texture is a closed cell textured surface.

2. The prosthesis of claim 1, wherein the first texture and the second texture are structured such that first texture encourages greater tissue ingrowth than the second texture.

3. The prosthesis of claim 1, wherein the lower pole region encompasses between about 20% and about 80% of the surface area of the exterior of the implantable member.

4. The prosthesis of claim 1, wherein the lower pole region encompasses between about 30% and about 70% of the surface area of the exterior of the implantable member.

5. The prosthesis of claim 1, wherein the lower pole region encompasses between about 40% and about 60% of the surface area of the exterior of the implantable member.

6. The prosthesis of claim 1, wherein the second texture is smoother than the first texture.

7. The prosthesis of claim 1, wherein the first texture extends along a posterior surface of the implantable member.

8. The prosthesis of claim 1, wherein the first texture extends along an anterior surface of the implantable member.

9. The prosthesis of claim 1, wherein the second texture extends along an posterior surface of the implantable member.

10. The prosthesis of claim 1, wherein the second texture extends along an anterior surface of the implantable member.

11. The prosthesis of claim 1, wherein the first texture comprises a band extending along the lower pole region of the implantable member.

12. The prosthesis of claim 11, wherein the first texture comprises a plurality of bands extending along the lower pole region of the implantable member.

13. The prosthesis of claim 1, wherein the second texture comprises a band extending along the upper pole region of the implantable member.

14. The prosthesis of claim 13, wherein the second texture comprises a plurality of bands extending along the upper pole region of the implantable member.

15. A breast prosthesis for implantation in a human being, the prosthesis comprising:

an implantable member comprising an elastomeric shell including an exterior surface defined by an anterior face and a posterior face; and

a fixation region comprising a fixation texture extending along the anterior face of the shell in a plurality of bands, the fixation texture being different from a texture along a balance of the anterior face of the shell.

16. The prosthesis of claim 15, wherein a balance of the exterior surface comprises a matte finish that is relatively less textured than the fixation region texture.

17. The prosthesis of claim 15, wherein each of the plurality of bands extend transversely relative to each other.
