Soft filled prosthesis shell with variable texture

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.

What is claimed is: 
     
         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 of the shell; and   the second region defined by a second surface of the shell that is different from the first textured surface of the shell;   the first textured surface being substantially defined by interconnected pores extending 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 interconnected pores of the first textured surface extend at least about two to about five pore diameters deep into the shell outer surface. 
     
     
         3 . The implant of  claim 1  wherein the pores have a diameter of between about 100 micron to about 1000 micron. 
     
     
         4 . 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. 
     
     
         5 . 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. 
     
     
         6 . The implant of  claim 1  wherein the pores have a diameter of between about 200 micron to about 800 micron. 
     
     
         7 . The implant of  claim 1  wherein the pores have a diameter of between about 300 micron to about 700 micron. 
     
     
         8 . The implant of  claim 1  wherein the pores have a diameter of between about 400 micron to about 600 micron. 
     
     
         9 . 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. 
     
     
         10 . The implant of  claim 1  wherein the second surface is a second textured surface different from the first textured surface. 
     
     
         11 . The implant of  claim 4  wherein the second textured surface is defined by pores extending no greater than about one pore deep into the shell outer surface. 
     
     
         12 . The implant of  claim 1  wherein the second surface is a substantially smooth surface relative to the first textured surface. 
     
     
         13 . The implant of  claim 1  wherein the first textured surface extends a depth of between about 0.8 mm to about 3.0 mm.
