Abstract
An implantable body including an outer membrane forming an enclosure for receiving a filler material. The surface of the outer membrane is characterized by a random distribution of peaks separated by valleys. The peaks and valleys are separated by gradual contoured slopes with a smooth transition between the peaks and valleys which are substantially free from indentation. The enhanced surface provides improved anchoring of the implant, yet reduces host reaction. The enhanced surface is formed by depositing a distribution of cured polymeric particles on an uncured tacky surface. This intermediate surface is then cured, followed by application of a layer of uncured elastomeric material. The entire surface is then cured to form the enhanced surface.
