Abstract

Tissue processing devices are provided. The tissue processing devices can be used to process and transport tissue in a closed and continuous environment. The devices can be used for adipose tissue transfer, including autologous fat grafting.

First claim

What is claimed is:

1. A tissue processing device, comprising:
a body including a cavity formed therein, the cavity comprising a first cylindrical compartment and a second compartment, and the body defining a proximal section and a distal section;
a tissue collection port formed in a wall of the body proximal section and adapted to receive tissue therethrough and in fluid communication with the cavity;
at least one injection port formed in fluid communication with the cavity;
a rotary transfer device comprising a helical blade and at least one catcher extending from a rotatable shaft of the rotary transfer device;
an automated actuation unit for rotatably driving the rotary transfer device;
a filter separating the first cylindrical compartment from the second compartment, wherein the filter defines at least a portion of a wall surrounding the rotary transfer device; and
an extrusion port formed in a wall of the body distal section and adapted for removal therethrough of the tissue from the cavity.

2. The tissue processing device of claim 1 , wherein the tissue collection port and the extrusion port are in fluid communication with the first cylindrical compartment.

3. The tissue processing device of claim 1 , wherein the helical blade is disposed within the first cylindrical compartment for transferring the tissue from the body proximal section to the body distal section.

4. The tissue processing device of claim 1 , wherein the at least one injection port comprises:
a first injection port formed in the wall of the body proximal section; and
second and third injection ports formed in a wall of the body distal section.

5. The tissue processing device of claim 4 , wherein the first, second, and third injection ports are in fluid communication with the cavity and adapted for injection of a wash solution therethrough.

6. The tissue processing device of claim 4 , wherein the first, second, and third injection ports are in fluid communication with the cavity and adapted for injection of a clean solution therethrough.

7. The tissue processing device of claim 1 , comprising a vacuum port formed in the wall of the body distal section, the vacuum port being in fluid communication with the second compartment.

8. The tissue processing device of claim 1 , wherein the body is formed from a transparent or semi-transparent material to allow for visualization of tissue during processing.

9. The tissue processing device of claim 1 , wherein the automated actuation unit comprises:
a graphical user interface connected to a computer or at least one processor; and
a motor configured to receive input regarding information related to actuation of the rotary transfer device.

10. A method of processing tissue, comprising:
providing a tissue processing device, the tissue processing device including:
a body including a cavity formed therein, the cavity comprising a first cylindrical compartment and a second compartment, and the body defining a proximal section and a distal section;
a tissue collection port formed in a wall of the body proximal section and in fluid communication with the cavity;
at least one injection port formed in fluid communication with the cavity;
a rotary transfer device including a helical blade and at least one catcher extending from a rotatable shaft of the rotary transfer device;
an automated actuation unit for rotatably driving the rotary transfer device;
a filter separating the first cylindrical compartment from the second compartment, wherein the filter defines at least a portion of a wall surrounding the rotary transfer device; and
an extrusion port formed in a wall of the body distal section;

introducing tissue for processing through the tissue collection port of the body proximal section and into the cavity;
actuating the rotary transfer device to transfer the tissue from the body proximal section to the body distal section; and
removing the tissue from the cavity through the extrusion port after the tissue has been processed.

11. The method of claim 10 , wherein the tissue collection port and the extrusion port are in fluid communication with the first cylindrical compartment.

12. The method of claim 10 , wherein the helical blade is disposed within the first cylindrical compartment for transferring the tissue from the body proximal section to the body distal section.

13. The method of claim 10 , wherein the at least one injection port comprises:
a first injection port formed in the wall of the body proximal section; and
second and third injection ports formed in a wall of the body distal section.

14. The method of claim 13 , further comprising injecting a wash solution into the cavity through the first, second, or third injection ports after introducing the tissue through the tissue collection port, and prior to removing the tissue from the extrusion port, to clean and process the tissue for transplantation.

15. The method of claim 10 , further comprising filtering the tissue of undesired components through the filter during transfer of the tissue from the body proximal section to the body distal section.

16. The method of claim 10 , further comprising extruding undesired components from the second compartment through a vacuum port formed in a wall of the body distal section prior to removing the tissue from the cavity.

17. The method of claim 10 , wherein the extrusion port is adapted to fluidically connect the first cylindrical compartment to an injection device and fill the injection device with processed adipose tissue within from first compartment.

18. The method of claim 17 , wherein the injection device is a syringe or cannula.

19. The method of claim 10 , wherein the tissue is human adipose tissue.

20. The method of claim 10 , wherein the automated actuation unit comprises:
a graphical user interface connected to a computer or at least one processor; and
a motor configured to receive input regarding information related to actuation of the rotary transfer device.
