Dr. Stoker uses fat transfer, also called fat grafting, to create fullness in other areas of the body using fat removed by liposuction. A Brazilian butt lift, for example, uses fat grafting. The power-assisted liposuction technique is especially useful for fat grafting. In clinical research conducted by Dr. Stoker and UCLA, more than 90% of fat cells removed using PAL remain viable for days and would be useful for fat grafts.
