Abstract

A wound dressing for use with a closure device is disclosed. The first and second base panels of the closure device are positioned on opposite lateral sides of a wound or incision. The base panels are coupled together to maintain wound or incision closure. A release liner is removed from a bottom surface of the wound dressing. The wound dressing is positioned over the closure device and the wound or incision. Exudate is absorbed by an absorbent material of the wound dressing through a porous strip of the wound dressing. The wound dressing is slightly larger than the closure device so that its perimeter area is adhered to the skin area around the closure device. Alternatively or in combination, the wound dressing is lightly adhered to the closure device and wound or incision area so that it can be removed without harming the underlying device and tissues.

Claims

1. A method of closing an incision or wound, the method comprising:

providing first and second base panels of a closure device configured to adhere to tissue adjacent first and second lateral sides, respectively, of the incision or wound, wherein each of the base panels comprises a plurality of force distribution structure distributed along a length thereof, and wherein the first and second base panels are coupled to one another by a plurality of lateral ties coupled to force distributions structures of the first and second base panels that are laterally adjacent one another;

coating the closure device with a low friction or non-stick coating;

curing the low friction or non-stick coating over the closure device; and

positioning a wound dressing over the cured coating and the closure device, with the closure device being adhered to tissue,

wherein the cured coating allows the wound dressing to be removed from the closure device while adherence of the first and second base panels with the tissue is maintained.

2. The method of claim 1, wherein the low friction or non-stick coating comprises a non-stick fluoropolymer coating, silicone compound, a silicone oil, or parylene.

3. The method of claim 1, wherein coating the closure device comprises coating the closure device with the low friction or non-stick coating at a thickness of 0.25 to 5.0 microns.

4. The method of claim 1, wherein curing the low friction or non-stick coating comprises curing the low friction or non-stick coating at a temperature of no more than 60 C.°

.

5. The method of claim 4, wherein curing the low friction or non-stick coating comprises curing the low friction or non-stick coating at a temperature of no more than 45 C.°

.

6. The method of claim 1, wherein the cured coating remains bound to the closure device after the wound dressing is removed.

7. The method of claim 1, wherein the cured coating is removed from the closure device concurrently with removal of the wound dressing.

8. The method of claim 1, further comprising masking at least one portion of the closure device before coating the closure device with the low friction or non-stick coating.

9. The method of claim 8, wherein masking at least one portion of the closure device comprises masking areas of the first and second base panels where adhesive of the panels are exposed.

10. The method of claim 1, wherein the low friction or non-stick coating comprises an anti-microbial coating.

11. The method of claim 1, wherein the cured coating is stretchable.

31. The method of claim 1, wherein positioning the wound dressing over the cured coating and the closure device, with the closure device being adhered to tissue comprises placing a first dressing part over a first longitudinal portion of the closure device and placing a second dressing part over a second longitudinal portion of the closure device, the second longitudinal portion being opposite the first longitudinal portion.

32. The method of claim 31, wherein at least a portion of the first or second dressing part overlaps with the other.

33. The method of claim 31, wherein positioning the wound dressing over the cured coating and the closure device comprises placing a third dressing part longitudinally between the first and second dressing parts.

12. A method of closing an incision or wound, the method comprising:

adhering first and second base panels of a closure device to tissue adjacent first and second lateral sides, respectively, of the incision or wound, wherein each of the base panels comprises a plurality of force distribution structure distributed along a length thereof, and wherein the first and second base panels are coupled to one another by a plurality of lateral ties coupled to force distributions structures of the first and second base panels that are laterally adjacent one another;

positioning one or more sacrificial cover strips over the first and second base panels that are adhered to the tissue;

wherein the one or more sacrificial cover strips adhere to the first and second base panels; and

positioning a wound dressing over the one or more sacrificial cover strips that are adhered to the first and second base panels, wherein the wound dressing adheres to the one or more sacrificial cover strips, and

wherein the one or more sacrificial cover strips allow the wound dressing to be removed while leaving the closure device adhered to the tissue.

13. The method of claim 12, wherein positioning the one or more sacrificial cover strips over the first and second base panels comprises extending perimeters of the one or more sacrificial cover strips over perimeters of the first and second base panels.

14. The method of claim 13, wherein the one or more sacrificial cover strips overlap full lengths of one or more of the first or second base panels.

15. The method of claim 12, wherein the one or more sacrificial cover strips comprise one or more perforations, notches, or cutout spaces.

16. The method of claim 12, wherein the one or more sacrificial cover strips comprise an elastic film layer.

17. The method of claim 12, wherein the one or more sacrificial cover strips comprise a pressure sensitive adhesive layer.

18. The method of claim 12, further comprising removing a release liner from the one or more sacrificial cover strips prior to the one or more cover strips being adhered to the first and second base panels.

19. The method of claim 12, wherein the one or more sacrificial strips comprise upper adhesive surfaces having a first adhesive tack and lower adhesive surfaces having a second adhesive tack less than the first adhesive tack.

34. The method of claim 12, wherein positioning the wound dressing over the cured coating and the closure device, with the closure device being adhered to tissue comprises placing a first dressing part over a first longitudinal portion of the closure device and placing a second dressing part over a second longitudinal portion of the closure device, the second longitudinal portion being opposite the first longitudinal portion.

35. The method of claim 34, wherein at least a portion of the first or second dressing part overlaps with the other.

36. The method of claim 34, wherein positioning the wound dressing over the cured coating and the closure device comprises placing a third dressing part longitudinally between the first and second dressing parts.
