Core Gel Study of the Safety and Effectiveness of Mentor Round Low Bleed Silicone Gel-filled Mammary Prostheses

Two types of Mentor Round Low-Bleed Silicone Gel-filled Mammary Prostheses will be used in the study: the Siltex textured surface device and the smooth surface device. Each implant is a silicone elastomer (rubber) mammary device that is supplied individually packaged in a doubled wrapped packaging system, sterile, and non-pyrogenic (does not cause fever). Each device consists of a silicone shell encasing a silicone gel filler material with a patch on the posterior side of the device. The basic smooth device shell consists of a silicone layer sandwiched in between two other silicone layers. This construction acts as a barrier to slow the diffusion of (spread) any gel filler materials through the shell. The Siltex textured shell consists of a smooth shell to which is bonded an additional layer of silicone with a textured pattern imprinted into its surface. The Siltex shell is intended to prevent tissue ingrowth. The implants will be available in sizes 100cc through 800ccs.
