Abstract:
1. A method for separating fat cells from a fat-fluid mixture, the method comprising the steps of: extracting a fat-fluid mixture from a human subject, providing one or more sponges formed of a fluid-absorbing material having pores with sizes in a range of about 0.2 mm to about 1 mm, and separating the fat component from the fat-fluid mixture without centrifugation by placing the one or more sponges in at least partial contact with the mixture so as to selectively absorb at least a portion of the fluid component of the mixture, wherein absorption of the fluid component by said one or more sponges results in a separated fat component exhibiting a fat cell density in a range of about 50% to 100% and which is suitable for injection into a selected portion of a human subject, and collecting the separated fat component.
