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.
St. Joseph Medical Center (Houston)
In the 1950s and 1960s, a number of notable physicians practiced at St. Joseph. Mavis Kelsey, who later founded the multispecialty Kelsey-Seybold Clinic, was a member of the medical staff. The hospital's plastic surgery chief, Dr. Thomas Cronin, met with representatives from Dow Corning in 1961 to discuss alternatives to sponge implants for breast augmentation. Dr. Cronin and his plastic surgery resident Frank Gerow are credited with developing silicone gel implants during those meetings with the company. The Dow Corning Cronin Dacron breast implant was used in 88% of breast augmentation procedures by the early 1970s.
