Abstract: The present invention provides a device and the method of use for the delivery of fat graft material to treat delicate anatomical areas. By use of the device and method very low amounts of fat can be administered and easily be controlled. This can be achieved by connecting the fat graft syringe assembly to a conventional delivery tubing system normally used for e.g. the controlled, low-volume application of local anesthetics. The driving force to move the fat particles through the syringe and the attached cannula is generated by a flow of normal saline solution which is triggered by the surgeon himself by use of a foot switch activating the electronic delivery device.
