Abstract
A surgically implantable, multi-lumen, high profile mammary implant includes a first, flexible, elastic lumen at least partly filled with a soft gel material and having a front wall approximating the shape of a human breast and a second, firmer, flexible lumen within the first lumen and connected thereto solely at the rear wall of the first lumen. The second lumen has a volume which is less than the volume of the first lumen and is at least partly filled with a second soft gel material. A third lumen preferably inflatably surrounds the first lumen and is inflated with saline solution. The second lumen is made firmer than any other lumen of the implant by providing it with a greater percent fill than any other lumen of the multi-lumen implant, filling it with a material which has a greater density than any materials filling any other lumen of the implant, providing it with thicker walls than any other lumen, or by filling it with material which has a greater crosslink density than the materials filling any of the other lumens. The multi-lumen structure has a high profile implant which is most suitable for breast reconstruction.
