Innovative Processing Technology Prepares Autologous Fat Grafts

A tissue processing technology facilitates fast, safe, and precise preparation of a patient's own fat for grafting procedures in cosmetic and reconstructive surgery.

The Cytori PureGraft System uses membrane-based tissue filtration technology that takes only 15 minutes to purify a fat graft ranging from 50 mL to 250 mL, removing excess and unwanted fluid, lipid, blood cells, and debris in a controllable manner. The patient's own fat tissue is rapidly prepared for reinjection and for use in aesthetic contouring. Used within the sterile field, the system filters out everything but the purified fat tissue, without centrifugation or other methods. The fat graft can be used to add volume to facial areas such as cheeks, tear troughs, chin and jowls, as well as reshaping the breasts and enhancing the buttocks.


The system uses a bilaminar-flow filtration technology to ensure a consistent graft. Tissue is injected into the system and is selectively filtered through the first membrane, removing loose blood cells, free lipids, fluid, and other debris resulting from the liposuction process. The second membrane directs the flow of the debris and allows for the draining of the contaminants into a waste bag. The tissue is washed twice with 150 mL of processing solution, which allows the physician to control the hydration level of the graft, important in addressing the varying quality of graft recipient sites and ensure graft quality. After the washing and draining is complete, the concentrated graft tissue can be extracted for use.

When used independently, the PureGraft system rapidly and reliably produces optimal graft tissue for use in fat grafting procedures; in combination with the Celution system, the PureGraft lowers processing times and increases processing volumes, improving the utility and efficiency of both products for soft tissue applications. The PureGraft System and the Celution system are products of Cytori Therapeutics (San Diego, CA, USA) and have received the European Community (CE) Mark of approval.

"The addition of PureGraft to our product portfolio allows us to offer a broad spectrum of autologous fat grafting technologies in Europe,” said Eric Daniels, M.D., managing director of Cytori for Europe and the Middle East. "In addition to Celution System, which enables cell-enriched fat grafting procedures, PureGraft fulfills the need for high quality, sterile tissue for fat grafting procedures, including body contouring.”
