Flexible bag for the preparation of adipose tissue grafts and relative kit

A flexible bag for the preparation of an adipose tissue graft from adipose tissue (TA)

• (I), which is provided with a proximal end and with a distal end and comprising:
• (a) a flexible, front wall and a flexible, rear wall, which are connected to one another so as to define a receiving space on the inside;
• (b) a first filter, which is arranged inside the bag so as to divide the receiving space into a first chamber (C1) and a second chamber (C2);
• the first filter is configured to micro-fragment a non-treated adipose tissue (TAN) to obtain a micro-fragmented adipose tissue (TAF);
• and
• (c) a second filter arranged inside the second chamber (C2) so as to obtain a third chamber (C3);
• the second filter is configured to obtain the graft (I) by separating a waste material (MS) from the micro-fragmented adipose tissue (TAF);
• wherein the first filter comprises a distal edge which is connected to the flexible, front wall between the proximal end and the distal end;
• and the second filter comprises a proximal edge which is connected to the flexible, rear wall between the proximal end and the distal end whereby the first filter and the second filter are spaced-apart from each other thereby inhibiting adherence of the first filter and the second filter to each other and collapse of the flexible bag during external deformation of the flexible bag pushing the adipose tissue through the flexible bag from the first filter to the second filter,
• wherein the first filter and the second filter are spaced-apart from each other along a longitudinal direction of the flexible bag.
