Abstract

An apparatus for closing a surgical incision comprises left and right base panels, a plurality of closure components, and a plurality of left and right axial supports coupled to the respective base panels. The closure components couple the left and right base panels to each other laterally and have left and right ends coupled to the respective base panels. The closure components are positioned laterally across the left and right panels, the left axial supports are disposed between pairs of left closure component ends, the right axial supports are disposed between pairs of right closure component ends, and the left and right axial supports are offset from one another such that a serpentine arrangement of consecutive closure components and axial supports is formed. The apparatus can be made of antimicrobial materials or materials impregnated with antimicrobial agents. A flexible adhesive cover can be provided over the apparatus when in use.

Claims

1. An incision closure apparatus comprising:

a first base panel for being adhered to a first side of an incision or wound, the first base panel comprising an upper surface and a tissue adherent lower surface;

a second base panel for being adhered to a second side of the incision or wound opposite the first side, the second base panel comprising an upper surface and a tissue adherent lower surface; and

a plurality of lateral ties coupling the first and second base panels to one another,

wherein the first and second base panels are axially stretchable and each comprise a plurality of preferentially separating regions distributed along lengths thereof, the plurality of preferentially separating regions facilitating one or more of axial or lateral stretching or separation of one or more of the first or second base panels.

2. The incision closure apparatus of claim 1, wherein the preferentially separating region comprises one or more perforations through the first or second base panels.

3. The incision closure apparatus of claim 1, wherein at least some of the one or more perforations are disposed along a lateral line across the first or second base panel.

4. The incision closure apparatus of claim 1, wherein the plurality of preferentially separating regions allow the first and second base panels to tear or separate into a plurality of base panel segments when axially stretched.

5. The incision closure apparatus of claim 1, wherein at least some of the plurality of preferentially separating regions are positioned along a lateral edge of the first or second base panel to reduce stress as underlying skin stretches radially outward from the incision or wound.

6. The incision closure apparatus of claim 1, further comprising a first plurality of axially spaced-apart supports coupled to the upper surface of the first base panel and a second plurality of axially spaced-apart supports coupled to the upper surface of the second base panel.

7. The incision closure apparatus of claim 6, wherein one or more of the first or second plurality of axially spaced-apart supports comprise force distribution structures.

8. The incision closure apparatus of claim 6, wherein at least some of the preferentially separating regions are axially disposed between axially adjacent supports on the first or second base panel.

9. The incision closure apparatus of claim 6, wherein one or more supports of the first or second plurality of axially-spaced apart supports is disposed axially adjacent an inner edge of the first or second base panel, respectively.

10. The incision closure apparatus of claim 6, wherein the supports comprise flexible, non-distensible materials.

11. The incision closure apparatus of claim 6, wherein the supports are embedded in or laminated to the upper surface of each panel.

12. The incision closure apparatus of claim 6, wherein one or more of the supports are C-shaped.

13. The incision closure apparatus of claim 1, wherein the plurality of lateral ties reversibly and adjustably couple the first and second base panels to one another such that a spacing between the first and second base panels is adjustable.

14. The incision closure apparatus of claim 13, wherein the lateral ties each have one end fixed to one of the first or second base panel and an opposite end adjustably attached to one of the opposite base panel, thereby allowing the lateral ties to draw the first and second base panels together to compress a wound or incision covered by the incision closure apparatus.

15. The incision closure appliance of claim 14, wherein the opposite end of each lateral tie is releaseably attached to a lock, and wherein the lateral tie and lock together form a ratchet tightening mechanism.

16. The incision closure apparatus of claim 1, wherein one or more of the first or second base panels comprise an elastic matrix.

17. The incision closure apparatus of claim 16, wherein the elastic matrix comprises an elastomeric membrane, a woven fabric, a spun fabric, rubber, latex, urethane, polyurethane, silicone, or a thermo plastic elastomer (TPE).

18. The incision closure apparatus of claim 17 wherein the elastic matrix comprises a fabric woven from elastic elements and having inelastic elements along lateral edges of the one or more of the first or second base panels and extending laterally thereacross.

19. The incision closure apparatus of claim 1, wherein the tissue adherent lower surface of one or more of the first or second base panels comprises a hydrophilic adhesive material.

20. The incision closure apparatus of claim 19, wherein the hydrophilic adhesive material comprises one or more of a hydrocolloid, a hydrogel, an acrylic polymer, or poly(ethylene glycol).

21. The incision closure apparatus of claim 1, further comprising a securing layer adapted to be placed over an assembly of the first and second base panels and the lateral ties after the assembly has been secured over the incision or wound.

22. The incision closure apparatus of claim 21, wherein the securing layer has an inner self-adhesive surface.

23. The incision closure apparatus of claim 21, wherein the securing layer is configured to laterally extend beyond an outer lateral edge of the first or second base panel.

24. The incision closure apparatus of claim 21, wherein the securing layer has one or more preferentially separating regions to allow the securing layer to at least partially stretch axially in response to axial stretching of the incision or wound and surrounding tissue the incision closure appliance is placed over.

25. A method of closing a wound or incision, the method comprising:

adhering a first base panel to a first side of an incision or wound;

adhering a second base panel to a second side of the incision or wound opposite the first side; and

coupling the first and second base panels together with a plurality of lateral ties,

wherein the first and second base panels are axially stretchable and each comprise a plurality of preferentially separating regions distributed along lengths thereof, the plurality of preferentially separating regions facilitating one or more of axial or lateral stretching or separation of one or more of the first or second base panels.

26. The method of claim 25, further comprising adjusting a spacing between the first and second base panels is adjustable with the plurality of lateral ties which reversibly and adjustably couple the first and second base panels to one another.

27. The method of claim 26, wherein the lateral ties each have one end fixed to one of the first or second base panel, and wherein coupling the first and second base panels together comprises adjustably attaching the opposite end to the opposite base panel, thereby allowing the lateral ties to draw the first and second base panels together to compress a wound or incision covered by the incision closure apparatus.

28. The method of claim 26, wherein the opposite end of each lateral tie is releaseably attached to a lock, and wherein the lateral tie and lock together form a ratchet tightening mechanism.

29. The method of claim 25, further comprising placing a securing layer over the first and second panels after the first and second panels have been coupled to one another.

30. The method of claim 25, wherein the securing layer is configured to laterally extend beyond an outer lateral edge of the first or second base panel.
