Breast augmentation
The modern prosthetic breast was invented in 1961, by the American plastic surgeons Thomas Cronin and Frank Gerow, and manufactured by the Dow Corning Corporation; in due course, the first augmentation mammoplasty was performed in 1962. There are five generations of medical device technology for the breast-implant models filled with silicone gel; each generation of breast prosthesis is defined by common model-manufacturing techniques.
Breast prostheses
Breast prostheses have a long history. In the 19th century they were made of rubber. On 22 September 1885, one Charles L. Morehouse received US patent 326915 for his "Breast-Pad", made of natural rubber and filled with air at normal pressure.
