Abstract

Methods and devices for treating lipoaspirate for use in fat grafting procedures are provided and generally include a canister for containing lipoaspirate, a separation mechanism structured to separate both oils and other materials from cellular components of lipoaspirate contained in the canister. The separation mechanism includes filters having different filtering capacities, for example, different pore sizes.

Claims

1. A method for treating lipoaspirate for use in fat grafting procedures, the method comprising:

containing lipoaspirate in a container, the container including a first filter element and a second filer element; and

moving the first filter element relative to a second filter element within the container to separate cellular components of the lipoaspirate from non-cellular components of the lipoaspirate.

2. The method of claim 1 wherein the first filtering element has a pore size different from a pore size of the second filtering element.

3. The method of claim 1 wherein the first filtering element is capable of separating blood/tumescent fluids from cellular materials in lipoaspirate.

4. The method of claim 1 wherein the second filtering element is capable of separating oils from cellular materials in lipoaspirate.

5. The method of claim 1 further comprising observing the separation and stopping the moving when a desired degree of separation is achieved.
