Abstract
An implantable tissue expansion device with an external surface layer of silicon elastomer, at least a portion of which contains a texture or open cell sturcture. The textured surface is expected to decrease subsequent capsular contracture and provide a non-skid surface to hold the device in position and permit differential expansion.
