An adipose tissue sizing device includes a first tube having a hollow inner portion, a sidewall radially extending around the hollow inner portion, a first end, and a second end opposite the first end. An inlet interface in fluid communication with the hollow inner portion of the first tube is configured to receive adipose tissue particles, and to allow the adipose tissue particles to pass into the hollow inner portion of the first tube. A filtering assembly, having a plurality of apertures therein, is positioned in the hollow inner portion of the first tube in a flow pathway of the adipose tissue particles, and is configured to resize the adipose tissue particles passing through the apertures according to a size of the apertures. An outlet interface in fluid communication with the hollow inner portion of the first tube is configured to allow the resized adipose tissue particles to pass out of the hollow inner portion of the first tube.
