This was the very first of the highly cohesive implants. It has been a widely used implant worldwide since the early 1990s. It comes in 12 different shapes for any given volume, giving the surgeon a wide range of shapes to choose from to create the ideal shape for a patient’s breasts. It is probably the firmest of the implants, though the additional firmness is not very distinguishable once in the body from other cohesive implants. In Europe there is a version of it called the 410 Soft Touch, which is a softer version of it. But the trade-off with that is that it has less of an ability to maintain its shape. The 410 had been in clinical trials in the United States since 2001 and was FDA approved in 2012. The company that launched the implant was called McGhan, which was later bought by Inamed, which was then bought by Allergan. So each of those names has been associated with the 410. Dr. Teitelbaum used hundreds of 410 implants during its clinical trial in the United States. He also was videotaped using the implants, and this video is part of Allergan’s physician teaching course on the proper use of the 410. Dr. Teitelbaum was also a primary writer of Allergan’s 410 educational curriculum. Photos of his own 410 patients are prominently displayed in Allergan’s 410 marketing materials, so he is undoubtedly a well-recognized expert using these implants.
