Abstract

A vascular access device includes an interior chamber for receiving a fluid and a filter within the interior chamber for filtering a pathogen within the fluid. A method of filtering a pathogen in a vascular access device includes providing a vascular access device having an interior chamber for receiving a fluid, providing a filter within the interior chamber of the vascular access device to move the fluid through the filter, and filtering a pathogen as the fluid moves through the filter.

Claims

1. A vascular access device, comprising:

a body,

an interior chamber disposed within the body for receiving a fluid, and

a filter within the interior chamber for filtering a pathogen within the fluid.

2. The vascular access device of claim 1, further comprising:

an antimicrobial agent within the interior chamber,

wherein the filter is impervious to the antimicrobial agent, and

wherein the filter borders the antimicrobial agent on at least a first side.

3. The vascular access device of claim 1, wherein the filter includes an electrical multilayer screen.

4. The vascular access device of claim 1, wherein the filter includes a biocide barb.

5. The vascular access device of claim 4, wherein the filter includes multiple layers of biocide barbs.

6. The vascular access device of claim 1, wherein the filter prevents the passage of any agent the size of a pathogen.

7. The vascular access device of claim 1, wherein the filter is treated with an antimicrobial agent.

8. A method of filtering a pathogen in a vascular access device, comprising:

providing a vascular access device having an interior chamber for receiving a fluid,

providing a filter within the interior chamber of the vascular access device,

moving the fluid through the filter, and

filtering a pathogen as the fluid moves through the filter.

9. The method of claim 8, further comprising:

providing an antimicrobial agent within the interior chamber, and

bordering the antimicrobial agent with the filter on at least a first side of the filter,

wherein the filter is impervious to the antimicrobial agent.

10. The method of claim 8, wherein filtering includes electrocuting the pathogen as it moves through the filter.

11. The method of claim 8, wherein filtering includes cutting the pathogen as it moves through the filter.

12. The method of claim 8, wherein the filter includes multiple layers of biocide barbs.

13. The method of claim 8, wherein filtering includes preventing the passage through the filter of any agent the size of the pathogen.

14. The method of claim 8, wherein the filter is treated with an antimicrobial agent.

15. A medical device, comprising:

means for accessing the vascular system of a patient, and

means for filtering a pathogen, wherein the means for filtering the pathogen is located within the means for accessing the vascular system of the patient.

16. The medical device of claim 15, wherein the means for filtering a pathogen includes a means for killing a pathogen bordered by a means for retaining the means for killing within the means for accessing.

17. The medical device of claim 15, wherein the means for filtering includes means for electrocuting the pathogen.

18. The medical device of claim 15, wherein the means for filtering includes means for cutting the pathogen.

19. The medical device of claim 15, wherein the means for filtering includes means for preventing the passage of any agent the size of the pathogen.

20. The medical device of claim 15, wherein the means for filtering includes a biocidal coating.
