Guest Blog: Dr. Diane Duncan on RFAL assisted liposuction

I just returned from the inaugural Brazilian-American meeting of plastic surgeons held last week by the ASAPS and ISAPS in beautiful Park City, Utah. The meeting was fantastic and melded some terrific techniques and presentation from both Brazilian and American physicians. This meeting was the brainchild of Renato Saltz, MD, an internationally respected plastic surgeon in Salt Lake City by way of Brazil.

One of the best presentations was by Diane Duncan, MD(pictured above), a leading plastic surgeon from Colorado who presented her data on Invasix, with whom she's been doing clinical trials for their RF liposuction/skin retraction device. On their website, it is billed as the first "RFAL," or Radio Frequency Assisted Liposuction device. What follows is a guest post by Dr. Duncan:

"One of the most exciting new technologies we have come across is made by a new Israeli company Invasix. Their device is a radiofrequency modulated liposuction and skin retraction device, currently being reviewed by the FDA for approval.

I have been doing some phase III clinical trials. This device is used internally during liposuction and caused unidirectional heating of the skin. The heating is more uniform than can be achieved with laser liposuction and quicker. The device also can control the amount of skin heating by decreasing energy when the skin achieves the correct temperature. This machine seems to offer a real advantage in obtaining localized skin surface area reduction without skin excision.

Many patients that we would have previously treated with an abdominoplasty may achieve excellent results with radiofrequency assisted liposuction alone. The next study will be a split abdomen study, comparing traditional liposuction to the radiofrequency modality. A 3-D CAD system will be used to measure both volumetric and skin surface area changes."

  2. Very interesting, indeed. Been doing some research into Velashape ii, a non invasive laser procedure. Looks promising.

  3. Undergoing liposuction with the use of latest technology is always a privilege of every patient to gain a maximum positive result. Thanks to the people behind every device and method discovery.

  4. The liposuction surgery is really very nice. It is very popular all over for removal of fat. People eho wants to get rid of body fat goes for the Liposuction. Nice article and great sharing.


  5. Dr. Pozner, will Invasix improve cellulite looks? From what you describe, it should. SmartLipo was also advertised to, but I still have doubts. Invasix sounds like a new approach.

  6. Absolutely brilliant post. Thanks for sharing with us.plastic surgery tampa fl.

  7. Liposuction is not a treatment for obesity or a substitute for proper diet and exercise.
    It is also not an effective treatment for cellulite – the dimpled skin that typically appears on the thighs, hips, and buttocks – or loose saggy skin.
