I googled the word (because my first thought was breast implants) and it means "insert or fix (tissue or an artificial object) in a person's body, especially by surgery."
The trend of people implanting hardware in their bodies is growing, but it is very niche. It's probably never going to go mainstream (but that might change in 50 years).
So for me, it's hard to say. Implanted.com could be a five figure name. The .net is worth what, maybe 1/20th?
If you waited long enough and the trend continues to grow, maybe someone wants to start a blog or magazine around people implanting stuff in their bodies. $1,000 if you're very lucky?
This is just my opinion though and I not experienced with .net sales. All I know is that there aren't a lot of sales with implant, so these kinds of names aren't moving off the shelf (unless they have to do with breast implants)
