Abstract

Systems, devices, and methods of the present disclosure assist with management of tubes and hoses during surgical procedures. The systems, devices, and methods provide for the proper opening and closing of tubes to facilitate performance of steps in a surgical procedure. Systems, devices, and methods of the present disclosure control fluid delivery to and from a medical device, including devices for tissue processing and cleaning.

Claims

1. A tissue treatment system, comprising:

a container, including;

an exterior wall surrounding an interior volume for holding tissue; and

a filter structure for processing tissue; and

a flow management device, including;

a first plate having a plurality of first openings passing therethrough;

a second plate having a plurality of second openings passing therethrough; and

a third plate having one or more third openings passing therethrough;

wherein the first plate, second plate, and third plate are operably connected and wherein setting the third plate in a first position places a first subset of the plurality of first openings in fluid communication with a first subset of the plurality of second opening, setting the third plate in a second position places a second subset of the plurality of first openings in fluid communication with a second subset of the plurality of second openings, and setting the third plate to a third position places a third subset of the plurality of first openings in fluid communication with a third subset of the plurality of second openings.

2. The tissue treatment system of claim 1, further comprising a rotatable connection to operably connect the first plate, the second plate, and the third plate.

3. The tissue treatment system of claim 1, further comprising a plurality of seals to prevent material from passing between the first plate and the third plate or the second plate and the third plate.

4. The tissue treatment system of claim 3, wherein at least one of the first plate, the second plate, and the third plate includes a plurality of recessed portions, and

wherein setting the first plate in a fourth position places the plurality of seals into the plurality of recessed portions and wherein none of the plurality of first openings is in fluid communication with a second opening.

5. The tissue treatment system of claim 1, further comprising at least one mixing blade to facilitate tissue washing or treatment.

6. The tissue treatment system of claim 1, wherein the first, second, and third positions of the third plate are configured to correspond to process steps in a tissue washing or processing procedure.

7. The tissue treatment system of claim 6, wherein the first position of the third plate are configured to correspond to a tissue aspiration step of the tissue washing or processing procedure.

8. The tissue treatment system of claim 6, wherein the second position of the third plate are configured to correspond to a tissue washing step of the tissue washing or processing procedure.

9. The tissue treatment system of claim 6, wherein the third position of the third plate are configured to correspond to a step of the tissue washing or processing procedure wherein tissue is transferred out of the container.

10. The tissue treatment system of claim 1, further comprising a transfer port in fluid communication with the interior volume.

11. The tissue treatment system of claim 1, further comprising a plurality of ports, each port in fluid communication with one of the plurality of first openings.

12. The tissue treatment system of claim 1, wherein the tissue treatment system is medically sterile.

13. The tissue treatment system of claim 1, wherein the container includes a first chamber and a second chamber divided by a dividing wall.

14. The tissue treatment system of claim 13, wherein the dividing wall is defined at least in part by the filter structure.

15. The tissue treatment system of claim 1, wherein the filter structure comprises a mesh wall and a frame supporting the mesh wall.

16. The tissue treatment system of claim 15, wherein the frame comprises a rigid material.

17. The tissue treatment system of claim 15, wherein the frame comprises a rigid material surrounding an upper border of the mesh wall.

18. The tissue treatment system of claim 15, wherein the frame comprises a rigid material surrounding an upper border of the mesh wall and extending along at least a portion of a side wall of the mesh wall to a bottom portion of the mesh wall.

19. The tissue treatment system of claim 15, wherein the frame comprises a rigid material surrounding an upper border of the mesh wall and having multiple extensions along at least a portion of a side wall of the mesh wall to a bottom portion of the mesh wall.

20. The tissue treatment system of claim 1, further comprising a transfer port at a bottom portion of the container.

21. The tissue treatment system of claim 20, wherein the transfer port is capable of fluid communication with a space inside the filter structure.

22. The tissue treatment system of claim 21, wherein the filter structure comprises a mesh wall and a frame supporting the mesh wall.

23. The tissue treatment system of claim 22, wherein the frame comprises a rigid material.

24. The tissue treatment system of claim 22, wherein the frame comprises a rigid material surrounding an upper border of the mesh wall.

25. The tissue treatment system of claim 22, wherein the frame comprises a rigid material surrounding an upper border of the mesh wall and extending along at least a portion of a side wall of the mesh wall to a bottom portion of the mesh wall, and wherein the frame is securely engaged with the transfer port.

26. The tissue treatment system of claim 22, wherein the frame comprises a rigid material surrounding an upper border of the mesh wall and having multiple extensions along at least a portion of a side wall of the mesh wall to a bottom portion of the mesh wall, and wherein the frame is securely engaged with the transfer port.

27. The tissue treatment system of claim 1, further comprising a wide base.

28. The tissue treatment system of claim 27, wherein the wide base has a widest dimension that is at least 10%, at least 20%, at least 30%, at least 40% greater than a widest dimension of a lowest portion of the container.

29. The tissue treatment system of claim 27, wherein the wide base has a widest dimension that is at least 10%, at least 20%, at least 30%, at least 40% greater than a widest dimension of a top of the tissue treatment system.
