Abstract

Embodiments of the present invention disclose a device for removing adipose tissue, comprising a self-contained syringe device comprising an inner syringe included within an outer syringe and wherein a filter is attached inside the outer syringe barrel; wherein the filter comprises a filter material that prevents premature filter collapse where the filter material is optionally coated to increase stiffness, and wherein liposuctioned adipose tissue is collected and purified inside the syringes. Methods of using the devices or system are also disclosed.

Claims

1. An adipose tissue collection and purification device comprising a self-contained syringe device comprising an inner syringe included within an outer syringe that comprises a barrel,

wherein a filter is attached inside the outer syringe barrel;

wherein the filter comprises a filter material, and

wherein lipoaspirated adipose tissue is collected and purified inside the syringes.

2. The adipose tissue collection and purification device of claim 1, wherein the filter has a mesh pore size between 30 micro meters and 3000 micro meters.

3. The adipose tissue collection and purification device of claim 1, wherein the inner syringe contained within the outer syringe is adapted to evacuate waste product from lipoaspirated adipose tissue into its barrel, and wherein the inner syringe is also adapted to contain within its barrel said waste product during reinjection of remaining adipose tissue contained within the filter inside the outer syringe.

4. The adipose tissue collection and purification device of claim 1, wherein the inner syringe comprises a plunger containing a one-way valve that allows for the passage of waste product from liposuctioned adipose tissue into a barrel of the inner syringe, said one-way valve prevents said waste product from reentering the outer syringe barrel.

5. The adipose tissue collection and purification device of claim 1, wherein the outer syringe is non-round shaped with a corresponding non-round shaped piston such that the piston is prevented from rotation while the inner syringe is being unscrewed.

6. The adipose tissue collection and purification device of claim 5, wherein the nonround shaped syringe provides extra grip to overcome an issue of grip caused by slipperiness of the adipose tissue.

7. The adipose tissue collection and purification device of claim 1, wherein the inner syringe is an inner waste chamber syringe that allows a waste product to evacuate from the lipoaspirated adipose tissue into a separate waste product chamber.

8. The adipose tissue collection and purification device of claim 1, wherein the inner syringe contains a wash fluid for washing the lipoaspirated adipose tissue, and

wherein the wash fluid also backflows into the filter to clean the filter.

9. The adipose tissue collection and purification device of claim 1, wherein the inner syringe attaches to a piston with a luer-activated port, thus the remaining outer syringe and piston forming a self-sealing system when the inner syringe is removed so as to prevent leaking and keep the device a closed system.

10. The adipose tissue collection and purification device of claim 1, wherein the outer syringe is added grip so as to overcome an issue of grip caused by slipperiness of the adipose tissue.

11. The adipose tissue collection and purification device of claim 1, wherein the syringe comprises a custom locking mechanism to allow the adipose tissue collection and purification device to be locked in the open position, thereby allowing for holding of a vacuum.

12. The adipose tissue collection and purification device of claim 1, further comprising a needle or a needle hub, wherein the needle or needle hub is attached to the self-contained syringe device.

13. The adipose tissue collection and purification device of claim 1, wherein the filter material is coated to increase stiffness so as to prevent premature filter collapse.

14. A method, comprising collecting and purifying an adipose tissue of a subject using a device, wherein the device comprising a self-contained syringe device comprising an inner syringe included within an outer syringe that comprises a barrel,

wherein a filter is attached inside the outer syringe barrel;

wherein the filter comprises a filter material, and

wherein lipoaspirated adipose tissue is collected and purified inside the syringes.

15. The method of claim 14, wherein the filter having a mesh pore size between 30 micro meters and 3000 micro meters.

16. The method of claim 14, wherein the inner syringe contained within the outer syringe is adapted to evacuate waste product from lipoaspirated adipose tissue into its barrel the inner syringe is also adapted to contain within its barrel said waste product during reinjection of remaining adipose tissue contained within the filter inside the outer syringe.

17. The method of claim 14, wherein the inner syringe comprises a plunger containing a one-way valve that allows for the passage of waste product from liposuctioned adipose tissue into a barrel of the inner syringe, said one-way valve prevents waste product from reentering the outer syringe barrel.

18. The method of claim 14, wherein the outer syringe is non-round shaped with a corresponding non-round shaped piston such that the piston is prevented from rotation while the inner syringe is being unscrewed.

19. The method of claim 18, wherein the non-round shaped syringe provides extra grip to overcome an issue of grip caused by slipperiness of the adipose tissue.

20. The method of claim 14, wherein the inner syringe is an inner waste chamber syringe that allows a waste product to evacuate from the lipoaspirated adipose tissue into a separate waste product chamber.

21. The method of claim 14, wherein the inner syringe contains a wash fluid for washing the lipoaspirated adipose tissue, and

wherein the wash fluid also backflows into the filter to clean the filter.

22. The method of claim 14, wherein the inner syringe attaches to a piston with a luer-activated port, thus the remaining outer syringe and piston forming a self-sealing system when the inner syringe is removed so as to prevent leaking and keep the device a closed system.

23. The method of claim 14, wherein the outer syringe is added grip so as to overcome an issue of grip caused by slipperiness of the adipose tissue.

24. The method of claim 14, wherein the syringe comprises a custom locking mechanism to allow the adipose tissue collection and purification device to be locked in the open position, thereby allowing for holding of a vacuum.

25. The method of claim 14, wherein the device further comprises a needle or a needle hub, wherein the needle or needle hub is attached to the self-contained syringe device.

26. The method of claim 14, wherein the filter material is coated to increase stiffness so as to prevent premature filter collapse.
