1. A method of processing adipose tissue that comprises a population of cells comprising adipose-derived stem cells for reintroduction into a patient, comprising:
- removing unprocessed adipose tissue that comprises a cell population comprising adipose-derived stem cells from said patient;
introducing the removed adipose tissue into a self contained adipose-derived stem cell processing unit configured to maintain a closed system wherein said self contained adipose-derived stem cell processing unit comprisesa tissue collection chamber that is configured to receive unprocessed adipose tissue that is removed from said patient, wherein the tissue collection chamber is defined by a closed system;
a first filter that is disposed within said tissue collection chamber, wherein said first filter is configured to retain a first component of said unprocessed adipose tissue and pass a second component of said unprocessed adipose tissue, such that said first filter separates said first component from said second component, and wherein said first component comprises a cell population comprising adipose-derived stem cells and said second component comprises lipid, mature adipocytes, and saline;
a processing chamber, which is configured to receive said first component comprising said population of cells comprising adipose-derived stem cells from said tissue collection chamber, wherein said processing chamber is within said closed system;
a conduit configured to allow passage of said first component comprising said cell population comprising adipose-derived stem cells from said tissue collection chamber to said processing chamber while maintaining a closed system;
a cell concentrator disposed within said processing chamber, which is configured to facilitate the concentration of said first component comprising said cell population comprising adipose-derived stem cells so as to obtain a concentrated population of cells comprising adipose-derived stem cells, wherein said cell concentrator comprises a centrifuge or a filter; and
an outlet configured to allow the aseptic removal of said concentrated population of cells comprising adipose-derived stem cells;
processing said removed, unprocessed adipose tissue to obtain said concentrated population cell comprising adipose-derived stem cells; and
introducing said concentrated population of cells that comprises adipose-derived stem cells into a prosthetic device, wherein said prosthetic device comprises a cell carrier portion and a cell carrier containment portion, and wherein said concentrated population of cells comprising adipose-derived stem cells is introduced into said cell carrier portion of said prosthetic device.
