Are there any machines available for at-home liposuction?

Liposuction may be common routine surgery, but it is still surgery.  It is invasive and thus requires at least local anesthesia and a sterile environment. 

No, there is no such device as yet.  

Besides, liposuction surgery is real surgery - with real risks.  You really do want this to be performed in a sterile operating room, in an accredited surgical facility, with a properly trained surgeon, surgical team and anesthesiologist.  These items are not available in most homes!!

All the best,
