Abstract
A textured breast implant is provided which generally includes a fluid fillable elastomeric shell having a texture defined by struts, for example, hollow struts, defining interconnected open cells. Methods of making the texture include applying a silicone dispersion to a base material and removing the base material from the coating to form a silicone-based structure comprising struts defining interconnected open cells, said struts including internal surfaces defining cavities within the struts. The method may further include the step of contacting the silicone based structure having cavities with a silicone dispersion to cause the silicone to enter and fill the cavities.

16. A method of making a material suitable for implantation in a mammal, the method comprising:
-
providing a base member including a porous surface defined by interconnected pores; contacting the base member with a fluid silicone-based material in a manner to cause the fluid material to enter the pores; applying a vacuum to the base member to draw the fluid material into the pores; removing excess fluid material from the base member to obtain a coating of the fluid material on the porous surface; and allowing the coating to set; removing the base material from the coating after allowing the coating to set to form a silicone-based structure comprising struts defining interconnected open cells, said struts including internal surfaces defining cavities within the struts; contacting the silicone based structure having cavities within the struts with a silicone dispersion to cause the silicone to enter and fill the cavities. - View Dependent Claims (15, 17, 18, 19)
