Abstract: A flexible bag for the preparation of an adipose tissue graft provided with a proximal end and a distal end and comprising: a front wall and a rear wall, which are connected to one another to define a receiving space on the inside; a first filter arranged inside the bag to divide the receiving space into a first chamber and a second chamber and to micro-fragment the adipose tissue to obtain a micro-fragmented adipose tissue; and a second filter arranged inside the second chamber to obtain a third chamber and to obtain the graft by separating a waste material from the micro-fragmented adipose tissue. The first filter comprises a distal edge which is connected to the front wall between the proximal end and the distal end and the second filter comprises a proximal edge which is connected to the rear wall between the proximal end and the distal end.
