Abstract

A luer adapter includes a body including an inner surface defining a lumen and first and second ends. Each end is adapted to connect to a medical device. An antimicrobial material is positioned at least on a portion of the inner surface. A barrier is positioned between the lumen and the antimicrobial material and permits the passage of the antimicrobial material therethrough upon exposure to moisture. The barrier may include hydrophilic material.

First claim

What is claimed is:

1. A luer adapter, comprising:
a body including an inner surface defining a lumen, and first and second ends, each end being adapted to connect to a medical device;
an antimicrobial material positioned on at least a portion of the inner surface; and
a barrier positioned between the lumen and the antimicrobial material, the barrier being bonded to the antimicrobial material, the antimicrobial material defining mounting structures with which the antimicrobial material and the barrier are constrained together, wherein the barrier permits the passage of the antimicrobial material therethrough upon exposure to moisture.

2. The luer adapter according to claim 1 , wherein the barrier includes a hydrophilic material.

3. The luer adapter according to claim 2 , wherein the antimicrobial material defines a layer positioned on the inner surface and the hydrophilic material defines a second innermost layer.

4. The luer adapter according to claim 2 , wherein the mounting structures include at least one rib.

5. The luer adapter according to claim 2 , wherein the mounting surface includes a roughened surface.

6. The luer adapter according to claim 2 , wherein the hydrophilic material includes biodegradable materials selected from the group comprising synthetic resins including those derived from alkylene carbonates, trimethylene carbonate, tetramethylene carbonate, caprolactone, valerolactone, dioxanone, polyanhydrides, polyesters, polyacrylates, polymethylmethacrylates, polyurethanes, glycolic acid, lactic acid, glycolide, lactide, polyhydroxy butyrates, polyorthoester, polyhydroxy alkanoates, homopolymers thereof, and copolymers thereof.

7. The luer adapter according to claim 2 , wherein the hydrophilic material includes non-biodegradable materials selected from the group comprising polyolefins, polyolefin blends, polyolefin copolymers, polyethylene, polydimethylsiloxane, polypropylene, ultra high molecular weight polyethylene, polyamides, polyesters, polyethylene terephthalate, polytetrafluoroethylene, polyethers, polyetherimides, polyether-esters, polybutester, polytetramethylene ether glycol, 1,4-butanediol, polyurethanes, styrenics, polycarbonates, vinyls, and combinations thereof.

8. The luer adapter according to claim 1 , wherein the antimicrobial material is selected from the group comprising silver, copper, and zinc.

9. The luer adapter according to claim 1 , wherein the antimicrobial material includes at least one zeolite material.

10. The luer adapter according to claim 9 , wherein the zeolite material is naturally occurring zeolite.

11. The luer adapter according to claim 9 , wherein the zeolite material is synthetic zeolite.

12. The luer adapter according to claim 11 , wherein the zeolite material includes ions selected from the group comprising silver, copper, and zinc.

13. A luer adapter, comprising:
a body including an inner surface defining a lumen, an outer surface, and first and second ends, each end being adapted to connect to a medical device;
an antimicrobial material positioned on at least one of the inner surface or the outer surface, the antimicrobial material comprising a polymer; and
a barrier positioned adjacent the antimicrobial material, the barrier being bonded to the polymer of the antimicrobial material, wherein the antimicrobial material is able to pass through the barrier upon exposure to moisture.

14. The luer adapter according to claim 13 , wherein the barrier includes a hydrophilic material.

15. The luer adapter according to claim 14 , wherein the hydrophilic material is radially adjacent the antimicrobial material with respect to a longitudinal axis of the body.

16. The luer adapter according to claim 14 , wherein the antimicrobial material comprises at least one antimicrobial element configured to dissolve in the presence of moisture.

17. The luer adapter according to claim 16 , wherein the hydrophilic material permits moisture to pass therethrough to enable the at least one antimicrobial element to dissolve.

18. The luer adapter according to claim 14 , wherein the antimicrobial material includes ions selected from the group consisting of silver, copper, and zinc.

19. The luer adapter according to claim 18 , wherein the hydrophilic material permits the ions to elute along the at least one of the inner surface or the outer surface.

20. The luer adapter according to claim 14 , wherein the hydrophilic material includes polymeric material.

21. The luer adapter according to claim 14 , wherein the body defines at least one annular recess for receiving the antimicrobial material.

22. The luer adapter according to claim 21 , wherein the hydrophilic material covers the at least one annular recess to enclose the antimicrobial material.

23. The luer adapter according to claim 13 , wherein the antimicrobial material defines an annular.

24. The luer adapter according to claim 13 , wherein the antimicrobial material includes antimicrobial glass.

25. The luer adapter according to claim 1 , wherein the barrier is mechanically bonded to the antimicrobial material.

26. The luer adapter according to claim 25 , wherein the mounting structures comprise an undercut, a rib, or a surface roughness.

27. The luer adapter according to claim 1 , wherein the barrier is chemically bonded to the antimicrobial material.

28. The luer adapter according to claim 27 , wherein the chemical bond comprises an adhesive bond between the barrier and the antimicrobial material.

29. The luer adapter according to claim 13 , wherein the barrier is mechanically bonded to the polymer of the antimicrobial material.

30. The luer adapter according to claim 13 , wherein the barrier comprises a polymer that is chemically bonded to the polymer of the antimicrobial material.

31. The luer adapter according to claim 13 , wherein the barrier comprises a polymer that is covalently bonded to the polymer of the antimicrobial material.

32. The luer adapter according to claim 13 , wherein at least one of the barrier or the antimicrobial material defines a mounting surface including mounting structures with which the barrier is bonded to the polymer of the antimicrobial material.

33. The luer adapter according to claim 27 , wherein the chemical bond comprises a molecular bond between the barrier and the antimicrobial material.
