Implantable devices designed for breast reconstruction and/or augmentation. These implants typically consist of an outer shell (e.g., silicone elastomer) that may include single or double (i.e., one shell inside the outer shell) lumen, a liquid or gel filler, and a patch to seal the shell once filled. The shell may be prefilled or filled during the surgery; some implants allow filler volume adjustment after implantation. Breast implants are available in a variety of surfaces, shapes, volumes, and shell thicknesses; they are usually filled with liquid (typically saline) and gel (typically silicone gel).
