Systems and methods for fat harvesting

A fat harvesting system, comprising:

• a reservoir body having an input fluid connector to receive bodily fluid including fat cells from a liposuction device so that the bodily fluid is deliverable into the reservoir body;
• a first screen positioned gravitationally below the input fluid connector and extending across the reservoir body, the first screen having a first screen size;
• a second screen positioned gravitationally below the first screen, the second screen having a tapered profile that slopes downwardly from an inner wall of the reservoir body to a collection chamber positioned along a midline of the reservoir body, the second screen having a second screen size that is smaller than the first screen size;
• a vacuum control housing that includes a first vacuum port in communication with the reservoir body above the first screen and a second vacuum port in communication with the reservoir body below the second screen, the first vacuum port and the second vacuum ports are positioned to remove a separated aqueous layer of the bodily fluid while a harvested fat layer including the fat cells remains in the reservoir body;
• a wiper rotatably mounted within the reservoir body so as to rotate about an axis of the reservoir body in response to movement of an actuator external to the reservoir body, the wiper having a set of blades disposed above the second screen;
• a conduit that extends from the collection chamber and is configured to connect to an extraction syringe to withdraw at least a portion of the fat cells from the collection chamber of the reservoir body;
• and
• an adjustable sizing screen positioned along the conduit and having a plurality of arcuate screen portions that are movable relative to the reservoir body so that said portion of the fat cells advance through a selected one of the arcuate screen portions before reaching the extraction syringe.
