NBC Network News highlighted the advantages of powered liposuction in a recent segment by Dr. Max Gomez which you can view or read. You may read an interview of Michael Brock, M.D. and Bruce Katz, M.D., two physicians who are impressed with the advantages of the Numed device. This practice advertisement which recently appeared in the New York Post is typical of those many surgical groups have placed as they have found the new technology to offer significant surgical advantages.
