Abstract

A barrier system is provided for use in reducing infections associated with post-operative surgical incision and/or a percutaneous medical device, such as a catheter, that is disposed within the surgical incision. Such a barrier system may 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. A tensioning anchor and associated system of two or more tensioning anchors is provided for post-operative wound closure. A method for applying and removing the barrier device and tensioning anchors is also provided.

First claim

The invention claimed is:

1. A surface barrier device for creating a barrier around an aperture in a patient's skin, comprising:
a top surface and a bottom surface, wherein the bottom surface is configured to make contact with said skin;
a compliant portion;
an enclosed inner chamber, wherein the inner chamber is at least partially enclosed by the complaint portion;
an adhesive composition, wherein the adhesive composition is applied to the compliant portion so as to adhere the compliant portion to said skin; and
a port configured to receive a fluid into the inner chamber, the compliant portion configured to expand upon receiving a fluid into the inner chamber, the expansion weakening a bond between the adhesive composition and the compliant portion.

2. The surface barrier device of claim 1 , further comprising a top layer and a bottom layer, wherein the inner chamber is enclosed between the top and bottom layers, a bottom surface of the bottom layer making contact with said skin, the bottom layer comprising one or more compliant portions.

3. The surface barrier device of claim 2 , wherein the bottom layer is comprised of a material with a thickness, the compliant portions of the bottom layer having a reduced thickness.

4. A method for removing the surface barrier device of claim 1 that has been adhered to a patient having skin using an adhesive composition, the method comprising:
injecting a fluid into the inner chamber; and
expanding the compliant portion, the expansion weakening a bond between the compliant portion and the adhesive composition.

5. The method of claim 4 further comprising exerting a force on the barrier device to detach the barrier device from the adhesive composition, wherein a portion of the adhesive composition remains on the skin of the patient.

6. The surface barrier device of claim 1 , wherein the compliant portion is a bladder disposed on the bottom surface of the surface barrier device, the enclosed inner chamber residing within the bladder.

7. The surface barrier device of claim 1 , wherein the compliant portion is a bladder disposed around the perimeter edges of the surface barrier device, the enclosed inner chamber residing within the bladder.

8. The surface barrier device of claim 1 , wherein the adhesive composition is a cyanoacrylate.

9. The surface barrier device of claim 1 , wherein the port comprises a Luer lock connection.

10. The surface barrier device of claim 1 , wherein a pressure sensitive adhesive composition is disposed on the bottom surface of the barrier device medial to the compliant portion.

11. The surface barrier device of claim 1 , wherein a pressure sensitive adhesive composition is disposed on the bottom surface of the barrier device lateral to the compliant portion.

12. The surface barrier device of claim 1 , wherein the port includes a one-way valve.

13. The surface barrier device of claim 1 , wherein the adhesive composition is enclosed in a plurality of capsules disposed on the bottom surface of the device, wherein the adhesive composition is released from the capsules and polymerizes, adhering the surface barrier device to the surface, when a pressure is applied to the capsules.

14. The surface barrier device of claim 1 , further comprising:
a seal, the seal covering and sealing the adhesive composition, wherein a rupture or removal of the seal exposes the adhesive composition, the adhesive composition polymerizing upon exposure.

15. The surface barrier device of claim 1 , further comprising an absorbent material disposed on the bottom surface of the device, the absorbent material located generally medial to the adhesive composition, wherein the absorbent material is configured to absorb excess fluids located on the surface and underneath the barrier device.

16. A method for providing a barrier on a skin surface, comprising:
providing a surface barrier device, the surface barrier device comprising:
a top surface and a bottom surface, wherein the bottom surface is configured to make contact with said skin surface;
a compliant portion;
an enclosed inner chamber, wherein the inner chamber is at least partially enclosed by the complaint portion; and
a port configured to receive a fluid into the inner chamber;

applying an adhesive composition to a surface contacting region of the compliant portion to adhere the compliant portion to said skin surface; and
securing the surface barrier device onto said skin surface, wherein the adhesive composition polymerizes, adhering the surface barrier device to said skin surface, the compliant portion configured to expand upon receiving a fluid into the inner chamber, the expansion weakening a bond between the adhesive composition and the compliant portion.

17. The method of claim 16 , further comprising providing a pressure sensitive adhesive on the bottom surface of the surface barrier device.

18. A kit for providing a wound barrier comprising:
a surface barrier device, the surface barrier device comprising:
a top surface and a bottom surface, wherein the bottom surface is configured to make contact with a surface;
a compliant portion;
an enclosed inner chamber, wherein the inner chamber is at least partially enclosed by the complaint portion;
an adhesive composition, wherein the adhesive composition is applied to the compliant portion so as to adhere the compliant portion to a surface; and
a port configured to receive a fluid into the inner chamber, the compliant portion configured to expand upon receiving a fluid into the inner chamber, the expansion weakening a bond between the adhesive composition and the compliant portion;

an adhesive composition; and
a syringe and or other injector for injecting a fluid.

19. The kit for of claim 18 , further comprising a surface disinfecting fluid and/or tool.
