... as I understand it, once the initial clinical trial of string implants was completed (I think it involved 100 patients or so), the FDA has banned further use of string implants in the USA pending an approval study. As this study would cost in excess of $100,000 with no guarantee of approval, and considering 99.9% of women who get breast implants are perfectly happy with breast sizes they can achieve straight out of a saline or silicone implant catalog, no implant company has been interested in funding such a study. It is because of the FDA ban on further use of string implants that Dr. Johnson was forced to stop doing them, as are all other plastic surgeons in the USA (and Canada). I have heard rumors that a Thai doctor is doing them, but that's a whole lot more risk and expense than I'd be willing to assume.
In regard to my friend Sable, I'll let her respond to your question directly, other than to state my own opinion that I think her new custom made implants look fan-f$%k!ng-tastic!
