Gummy implants

Are these available in the US now? 

Never heard of them.

"Gummy bear" implants are also called form stable implants, and they are essentially semi-solid implants that are teardrop shaped.  They are suitable for patients desiring a modest augmentation with no loose skin.  They require a very precise "fit" of the implant to the pocket to prevent rotation of the teardrop (or anatomically) shaped implant, which looks bad.

My personal opinion is that they will benefit a rather small number of patients. The benefit is they never rupture.  The FDA has been slow to approve them.

Here is a video of me demonstrating the way the gel behaves in the implants we currently are using:

Thank you DrL. I'm a huge fan of your work, as I have seen it several times on people's profiles. I suppose what made me want the gummy over the other options out there is that they feel more natural. I've seen some people with thin skin where you can see the shape of the implant if they move a certain way. This concerns me. I do some arial sports where I will be upside down for certain moves and I do not want the implants to shift up toward my neck and look unusual. Most of these costumes are very tight and revealing, simular to ice skating costumes. The video did show how much the gel is unlikely to leak through your body. On the other hand, a tear dropped shape implant moving around and perhaps going sideways or upside down would also be terrible. 

The first of these type of higher cohesive ("gummy bear") silicone implants was approved last summer from a company called Sientra. There is still pending approval of even more form stable devices from 2 other companies, which are really more suited to breast reconstruction rather then cosmetic surgery as they are kind of too stiff.

Generally speaking, if you don't have smaller and better shaped breasts to start with, the shaped "gummy" implants offer less of an advantage. You'd be better off with the traditional round devices and save $300-400 on the less cost of the round devices. The round Sientra implants are still made of a different polymer from the other companies that more stable in shape and seem to offer many of the potential benefits of the shaped implants.
