Abstract: A device for transplanting body fat includes a chamber in the form of a hollow cylinder divided by a plunger guidable on an inner casing surface of the chamber into a proximal portion and a distal portion which is fluidically decoupled from said proximal portion. A piston connected to the plunger has an end which has a fluidic connection extending through the plunger to the chamber, and the plunger is configured as a filter in the region of the fluidic connection, and the distal end of the piston comprises a first closable media connection and means for guiding fluids and/or fatty tissue are connectable to the chamber, wherein fluid and/or fatty tissue can be sucked into the proximal portion of the chamber and/or in through the plunger by supplying the first media connection in the open state with a negative pressure.
