Abstract

The present specification discloses a backing plate comprising a front surface and a back surface comprising a plurality of parallel ridges and grooves, and soft tissue implants comprising such backing plates.

Claims

1. A breast prosthesis comprising:

a elastic anterior portion; and

a backing plate, secured to the anterior portion and forming a posterior portion of the prosthesis, the backing plate comprising a surface defined by a plurality of spaced apart ridges.

2. The prosthesis of claim 1, wherein the spacing between the ridges is varied.

3. The prosthesis of claim 2, wherein the varied spacing between the ridges is irregular.

4. The prosthesis of claim 1, wherein the ridges are of different heights.

5. The prosthesis of claim 1, wherein the height of each of the ridges is at least 0.5 mm.

6. The prosthesis of claim 1, wherein the height of each of the ridges is from about 0.5 mm to about 5 mm.

7. The prosthesis of claim 1, wherein the ridges are of different widths.

8. The prosthesis of claim 1, wherein the width of each of the ridges is at least 0.5 mm.

9. The prosthesis of claim 1, wherein the width of each of the ridges is from about 0.5 mm to about 5 mm.

10. The prosthesis of claim 1, wherein the backing plate has a flexibility between the ridges to enable the backing plate to form a substantially rolled configuration.

11. The prosthesis of claim 1, wherein the backing plate further comprises a valve.

12. The prosthesis of claim 1 in the form of a tissue expander.

13. A breast prosthesis comprising:

a fillable, elastic anterior portion; and

a flexible backing plate, secured to the anterior portion and forming a posterior portion of the prosthesis, the anterior portion and the backing plate defining a fluid-fillable cavity therebetween;

the backing plate comprising a surface defined by a plurality of alternating ridges, the ridges having at least one of varied heights or varied widths and having a flexibility between the ridges to enable the backing plate to form a substantially rolled configuration;

the backing further comprising a valve for facilitating filling of the chamber.
