Adipose-derived MSCs microfragmentation and purification kit.
LIPO-STEM DUO™ is a closed-circuit single-use kit for adipose tissue microfragmentation and purification without any centrifuge and with minimal manipulation.
The filtering system consistently microfragments the adipose tissue while maintaining its biological properties and maximizing the regenerative potential of the organism.
The entire processing phase of the liposuctioned tissue occurs inside the device thanks to continuous saline solution washing.
This allows reducing the cellular stress, eliminating any traumatic action that may damage the extracellular matrix and its essential trophic and anti-inflammatory function.
The collection and processing bag is equipped with two filters:
- the first filter microfragments the adipose tissue, while retaining the eventual fibrotic tissue
- the second filter with denser mesh retains the reduced (microfragmented) adipose tissue that is washed with saline solution, eliminating all the oily and blood residues which might cause inflammation of the treated tissues.
The final microfragmented and purified product is an autologous adipose tissue that keeps the biological properties of the original tissue intact and can easily be injected, even through very thin needles.
KEY ADVANTAGES

HOW DOES IT WORK?
SURGICAL TECHNIQUE
1. Infiltrate the Klein solution in the selected harvest site using the 16 G Klein cannula
2. Harvest the adipose tissue from the anaesthetized area using the 13 G lipoaspiration cannula.
3. Connect a 2L saline bag to the device’s “WASH IN” valve and fill the device.
4. Insert the harvested adipose tissue in the device’s “LIPO IN” valve.
5. The collection and processing bag is equipped with two filters: the first filter microfragments the adipose tissue while retaining the eventual fibrotic tissue.
6. Support the purification of the adipose tissue using the processing spatula. This will gently microfragment and purify the adipose tissue.
7. The second filter with a denser mesh retains the microfragmented adipose tissue and discharges the pro-inflammatory contents and liquids in the waste bag.
8. The eventual fibrotic tissue is retained in the first filter, allowing to obtain a high qualitative adipose tissue.
9. Continue to gently move the processing spatula on the filter to facilitate the complete washing of the tissue.
10. Once the final product acquires a clear yellow colour, stop the saline solution flow and gently remove the excess of water using the processing spatula.
11. With the help of the processing spatula, retrieve the purified and microfragmented adipose tissue from the dedicated “LIPO OUT” valve and use it as needed.
COMPONENTS
– LIPO-STEM DUO™ device
The device is supplied ready-to-use with a 400 ml capacity processing bag and a 2 lt waste-collecting bag. The kit includes a processing spatula to facilitate tissue purification.
The system has 3 valves:
– WASH IN: to connect the saline solution
– LIPO IN: to transfer the harvested adipose tissue into the device
– LIPO OUT: to extract the microfragmented and purified adipose tissue.

Filtering system
The sophisticated filtering system inside the processing and filtering bag is equipped with two filters:
- the first filter microfragments the adipose tissue, while retaining the eventual fibrotic tissue
- the second filter with denser mesh retains the reduced (microfragmented) adipose tissue that is washed with saline solution, eliminating all the oily and blood residues which might cause inflammation of the treated tissues.
16 G Klein solution cannula with 60 ml syringe
The kit includes:
- two 60 ml syringes for Klein solution infiltration
