Abstract

A device for the capture and adsorption of blood-borne materials of interest comprising a fluidic cartridge with at least one inlet and at least one outlet; a multidirectional fluidic channel between the at least one inlet and the at least one outlet; said multidirectional fluidic channel comprising at least one inner wall; and a substance coating at least a portion of the at least one inner wall of the multidirectional fluidic channel.

Claims (28)

1. A device for the capture and adsorption of blood-borne materials of interest, the device comprising:

a fluidic cartridge with at least one inlet and at least one outlet;

two or more filter plates, each filter plate having at least one plate inlet, at least one plate outlet, and a fluidic channel, wherein the fluidic channel comprises a curved shape wherein the fluidic channel is fluidically connected with the at least one plate inlet and the at least one plate outlet, wherein the two or more filter plates are arranged in a stackable plate configuration to collectively form a multidirectional fluidic channel having at least one inner wall, and wherein the multidirectional fluidic channel is fluidically connected with the at least one inlet and the at least one outlet of the fluidic cartridge; and

a first substance coating at least a portion of the at least one inner wall of the first multidirectional fluidic channel, wherein the first substance is effective to capture or to adsorb blood-borne materials, wherein a curvature of the multidirectional fluidic channel is configured to promote the capture or the adsorption of the blood-borne materials by the first substance coating the inner wall when the blood-borne materials of interest is flowed through the multidirectional fluidic channel.

2. The device of claim 1 , wherein the first substance is selected from the group consisting of: antibodies, crosslinking agents, peptides, proteins, antibiotics, polymers, amines, polyethers, amino acids, aptamers, tumor necrosis factors, adhesion receptors, E-selectin, cytokines, chemotherapy agents, quorum sensing proteins, quorum sensing receptors, and biological agents.

3. The device of claim 2 , wherein the first substance comprises a fixed, covalently-bonded antibiotic.

4. The device of claim 3 , wherein the fixed, covalently-bonded antibiotic is polymyxin or vancomycin.

5. The device of claim 4 , wherein an amount of the polymyxin or the vancomycin is at least 0.5 mM.

6. The device of claim 5 , wherein the amount of the polymyxin or the vancomycin is about 1.0 to about 50.0 mM.

7. The device of claim 1 , wherein the first substance comprises a fixed crosslinking agent selected from the group consisting of: hexamethylene diamine, polyethylene glycol, polyethylene glycol derivatives, N-hydroxysuccinimide esters, and glycine.

8. The device of claim 1 , wherein the multidirectional fluidic channel comprises a thermoplastic polymer base material that has at least one surface exposed functional group selected from the group consisting of: carbonyl groups, carboxyl groups, alcohol groups, amino groups, chloride groups, styrene groups, alpha-halogenated acyl group, benzyl groups, and isocyanic acid groups.

9. The device of claim 1 , wherein the multidirectional fluidic channel has a width of about 0.01 to about 1,000.0 mm, wherein the multidirectional fluidic channel has a height of about 0.001 to about 100.0 mm, or wherein the multidirectional fluidic channel has a length of 0.1 to 10,000 mm.

10. The device of claim 1 , wherein the multidirectional fluidic channel is spiral or helical shaped.

11. The device of claim 10 , wherein a spiral or a-helix of the multidirectional fluidic channel has an outer-most radius of curvature of about 1.0 to about 1,000.0 mm.

12. The device of claim 10 , wherein a spiral or a helix of the multidirectional fluidic channel has a distance of about 1.0 to about 10.0 mm between a first portion of the multidirectional fluidic channel and second portion of the multidirectional fluidic channel as measured by a center to center distance between loops of the multidirectional fluidic channel.

13. The device of claim 1 , wherein the at least one inlet or the at least one outlet comprises a fitting, a cap, or a luer lock connector to attach the multidirectional fluidic channel to a tubing.

14. The device of claim 1 , wherein the stackable plate configuration comprises a number of plates within a range from 2 plates to 25 plates.

15. The device of claim 1 , further comprising a second multidirectional fluidic channel comprising at least one inner wall, wherein the first substance coating at least a portion of the at least one inner wall of the first multidirectional fluidic channel comprises a first antibiotic, and wherein a second substance coating at least a portion of the at least one inner wall of the second multidirectional fluidic channel comprises a second antibiotic.

16. The device of claim 15 , wherein the first substance and the second substance are different substances.

17. The device of claim 15 , wherein the multidirectional fluidic channel comprises a stackable plate configuration; wherein the stackable plate configuration comprises a number of plates within a range from 2 plates to 25 plates; wherein the second multidirectional fluidic channel comprises a stackable plate configuration; and wherein the stackable plate configuration comprises a number of plates within a range from 2 plates to 25 plates.

18. The device of claim 1 , wherein the first substance is effective to capture or adsorb one or more of a Gram-negative bacterium, a Gram-positive bacterium, or an endotoxin.

19. The device of claim 1 , wherein the first substance is effective to capture or to adsorb a Gram-positive bacterium or a Gram-negative bacterium with a capture capacity of 10 5 colony forming units or greater.

20. The device of claim 15 , wherein the first substance and the second substance are effective to capture or to adsorb a Gram-positive bacterium or a Gram-negative bacterium the blood-borne material with a capture capacity of 10 5 colony forming units or greater.

21. The device of claim 1 , wherein the first substance comprises porous beads.

22. The device of claim 1 , wherein the multidirectional fluidic channel comprises heparin disposed therein.

23. The device of claim 1 , wherein the multidirectional fluidic channel comprises a thermoplastic polymer base material that is functionalized with a polymer or co-polymer selected from the group consisting of: polycarbonate, vinylchloride, vinylacetate, acrylamide, polyethylene, polyethylene terephthalate acrylic acid, acrylonitrile, maleic anhydride, and methylmethacrylate.

24. The device of claim 1 , wherein the first substance comprises a fixed, covalently-bonded polypeptide antibiotic.

25. The device of claim 24 , wherein the fixed, covalently-bonded polypeptide antibiotic is polymyxin or colistin.
