Abstract

A soft prosthetic implant, such as a silicone breast implant, is provided. The implant has a variety of different surfaces, for example, different textures, located on different areas of the outer surface of the implant.

Claims

1. A breast implant comprising:

an elastomeric shell comprising a first region and a second region, and an outer surface;

the first region defined by a first textured surface; and

the second region defined by a second textured surface, the second textured surface defined by open pores extending no greater than about one pore deep into the shell outer surface;

the first textured surface being defined by interconnected pores extending about two to about five pores deep to a depth of between about 0.2 mm to about 5.0 mm into the shell outer surface.

2. The implant of claim 1 wherein the pores have a diameter of between about 100 micron to about 1000 micron.

3. The implant of claim 1 wherein at least about 70% of the pores have a diameter of between about 100 micron to about 1000 micron.

4. The implant of claim 1 wherein at least about 90% of the pores have a diameter of between about 100 micron to about 1000 micron.

5. The implant of claim 1 wherein the pores have a diameter of between about 200 micron to about 800 micron.

6. The implant of claim 1 wherein the pores have a diameter of between about 300 micron to about 700 micron.

7. The implant of claim 1 wherein the pores have a diameter of between about 400 micron to about 600 micron.

8. The implant of claim 1 wherein at least about 90% of the pores have a diameter of between about 400 micron to about 600 micron.

9. The implant of claim 1 wherein the first textured surface is defined by interconnected pores extending two to five pores deep.

10. The implant of claim 1 wherein the comprise negative impressions of texturing particles.
