Curly Blonde Girl Shows Off Her Silicone Breast Implants On The Couch At Home

The second technological development was a polyurethane foam coating for the implant shell; it reduced the incidence of capsular contracture by causing an inflammatory reaction that impeded the formation of a capsule of fibrous collagen tissue around the breast implant. Nevertheless, the medical use of polyurethane-coated breast implants was briefly discontinued because of the potential health-risk posed by 2,4-toluenediamine (TDA), a carcinogenic by-product of the chemical breakdown of the implant’s polyurethane foam coating. After reviewing the medical data, the U.S. Food and Drug Administration concluded that TDA-induced breast cancer was an infinitesimal health-risk to women with breast implants, and did not justify legally requiring physicians to explain the matter to their patients. In the event, polyurethane-coated breast implants remain in plastic surgical practice in Europe and in South America; in the U.S., no breast implant manufacturer has sought the FDA’s approval for American medical sale.
The third technological development was the double lumen breast-implant, a double-cavity device composed of a silicone-implant within a saline-implant. The two-fold, technical goal was: (i) the cosmetic benefits of silicone-gel (the inner lumen) enclosed in saline solution (the outer lumen); (ii) a breast-implant device the volume of which is post-operatively adjustable. Nevertheless, the more complex design of the double-lumen breast-implant suffered a device-failure rate greater than that of single-lumen breast implants. The contemporary versions of Second generation devices, presented in 1984, are the “Becker Expandable” models of breast implant device, used primarily for breast reconstruction.
- Third and Fourth generations
In the 1980s, the models of the Third and of the Fourth generations of breast-implant devices were sequential advances in manufacturing technology, e.g. elastomer-coated shells that decreased gel-bleed (filler leakage), and a thicker filler (increased-cohesion) gel. Sociologically, the manufacturers then designed and fabricated varieties of anatomic models (natural breast) and shaped models (round, tapered) that realistically corresponded with the breast and body types presented by women patients. The tapered models of breast implant have a uniformly textured surface, to reduce rotation; the round models of breast implant are available in smooth-surface and textured-surface types.
