The system uses a bilaminar flow filtration technology to ensure a consistent graft. Tissue is injected into the PureGraft™ 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. This washing step allows physicians to control the hydration level of the graft. The right balance of hydration can be 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 in body contouring.

For best results, Cytori recommends the use of Celbrush™ for delivery of PureGraft™-processed graft.
