Abstract
A device and method for producing refined adipose tissue for use in autologous adipose transplantation or research wherein a sterile environment is maintained. More particularly, a system for refining tissue comprising a first flexible container, a second flexible container having a plurality of pores providing for fluid communication between the interior of the first flexible container and the interior of the first enveloping flexible container, a first port that provides communication between the exterior environment and the interior of the first flexible container and thereby provides a means for introducing fluids into the interior of the first flexible container and allowing waste effluent to exit the first container, a second flexible container, a second port for inserting tissue into the second container and expressing refined tissue out of the container, and a means for controlling the opening and closing of the first and second ports. The method comprises introducing a tissue sample into the system and subjecting it to a washing phase wherein the tissue is agitated, the waste effluent is allowed to exit the system through the first port, and the refined tissue is expressed out the second port for further refinement or transplantation.
