Abstract

A barrier system is provided for use in reducing infections associated with a percutaneous medical device, such as a catheter, that is disposed within a percutaneous incision. Such a barrier system can include: a barrier device having a skin-contacting surface and a catheter-receiving surface; and an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin. The barrier device can include a conduit configured to receive the catheter. Alternatively, the barrier device can include a groove in a base surface that is configured to receive the catheter. A system that includes a medical device, the barrier device, and adhesive can also be provided.

Claims

1. A barrier system for reducing infections associated with a catheter, said barrier system comprising:

a barrier device having a skin-contacting surface and a catheter-receiving surface; and

an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin.

2. The barrier system as in claim 1, wherein the adhesive is a cyanoacrylate.

3. The barrier system as in claim 2, wherein the cyanoacrylate is ethyl-2-cyanoacrylate, and 2-octyl cyanoacrylate, or n-butyl-cyanoacrylate

4. The barrier system as in claim 1, wherein barrier device includes a conduit configured to receive the catheter.

5. The barrier system as in claim 1, wherein the barrier device includes a groove in a base surface that is configured to receive the catheter.

6. The barrier system as in claim 4, wherein the barrier device includes a base surface having a base opening that is in fluid communication with the conduit and an opposite surface having an opposite opening that is in fluid communication with the base opening via the conduit.

7. The barrier system as in claim 6, wherein the conduit is substantially orthogonal with the base surface.

8. The barrier system as in claim 6, wherein the conduit is at an angle from about 0 degrees to about 90 degrees with respect to the base surface.

9. The barrier system as in claim 1, further comprising at least one of the following:

a fastener disposed on the barrier device that is configured for receiving the catheter;

one or more fastener straps on the barrier device that is configured to be affixed to the skin outward from the barrier device;

a tapered base opening or opposite opening;

a uniform conduit cross-sectional profile;

a tapered conduit cross-sectional profile;

a recess in the conduit configured for receiving the adhesive;

a recess in the base surface configured for receiving the adhesive;

a clam slit;

a groove adjacent with the opposite opening;

an o-ring;

a chilling fluid conduit in the barrier device that communicates with a location for receiving the adhesive;

an expandable bladder disposed on the barrier device;

or

a release cord disposed on the base surface of the barrier device.

10. A barrier system as in claim 1, wherein the barrier device is disposed on the skin with the adhesive therebetween so as to receive the catheter protruding from the incision.

11. A catheter system for reducing infections associated with catheters, said catheter system comprising:

a catheter medical device;

a barrier device having a skin-contacting surface and a catheter-receiving surface; and

an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin.

12. The catheter system as in claim 11, wherein the adhesive is a cyanoacrylate.

13. The catheter system as in claim 12, wherein the cyanoacrylate is ethyl-2-cyanoacrylate, and 2-octyl cyanoacrylate, or n-butyl-cyanoacrylate

14. The catheter system as in claim 11, wherein barrier device includes a conduit configured to receive the catheter.

15. The catheter system as in claim 11, wherein the barrier device includes a groove in a base surface that is configured to receive the catheter.

16. The catheter system as in claim 14, wherein the barrier device includes a base surface having a base opening that is in fluid communication with the conduit and an opposite surface having an opposite opening that is in fluid communication with the base opening via the conduit.

17. The catheter system as in claim 16, wherein the conduit is substantially orthogonal with the base surface.

18. The catheter system as in claim 16, wherein the conduit is at an angle from about 0 degrees to about 90 degrees with respect to the base surface.

19. The catheter system as in claim 11, further comprising at least one of the following:

a fastener disposed on the barrier device that is configured for receiving the catheter;

one or more fastener straps on the barrier device that is configured to be affixed to the skin outward from the barrier device;

a secondary conduit filled with another material;

an expandable bladder disposed on the barrier device;

or

a release cord disposed on the base surface of the barrier device.

20. A catheter system as in claim 11, wherein the barrier device is disposed on the skin with the adhesive therebetween so as to receive the catheter protruding from the incision.

21. A method for reducing infections associated with percutaneous medical devices, said method comprising:

inserting, percutaneously, a medical device into skin of a subject;

applying an adhesive composition to the skin and a barrier device, said barrier device having a skin-contacting surface and a medical device-receiving surface; and

adhering a barrier device to the skin with the adhesive composition so as to form an anti-microbial barrier with respect to the incision and medical device that inhibits microbes from infecting the incision.

22. A method as in claim 21, further comprising applying the adhesive composition to the medical device so as to adhere the medical device to the barrier device and/or skin so as to form an anti-microbial barrier that inhibits microbes from infecting the incision.

23. A method as in claim 21, wherein the adhesive is a cyanoacrylate.

24. A method as in claim 21, further comprising applying the adhesive onto at least one of the skin-contacting surface or medical device-contacting surface of the barrier device.
