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:

first and second base panels for being adhered to first and second sides of an incision or wound, respectively, each base panel comprising an upper surface, a tissue adherent lower surface, an outer lateral edge, and an inner lateral edge for placement adjacent the incision or wound;

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

at least one skirt coupled to one or more of the first base panel upper surface or the second base panel upper surface, the at least one skirt extending laterally beyond the outer lateral edge of the one or more of the first base panel upper surface or the second base panel upper surface, the at least one skirt having a tissue adherent lower surface,

wherein the at least one skirt has greater compliance than a composite structure of the first and second base panels and the plurality of lateral ties for providing strain relief between exposed skin lateral of the at least one skirt and one or more of the first base panel or second base panel, as well as between skin covered by the first and second base panels and the tissue adherent lower surfaces of the first and second base panels.

2. The incision closure apparatus of claim 1, wherein the at least one skirt comprises a first skirt and a second skirt, wherein the first skirt is coupled to the upper surface of the first base panel and extends laterally from the outer lateral edge of the first base panel, and wherein the second skirt is coupled to the upper surface of the second base panel and extends laterally from the outer lateral edge of the second base panel.

3. The incision closure apparatus of claim 2, wherein the first and second skirts extend laterally outward from the inner lateral edges of the first and second base panels, respectively, for leaving the incision or wound uncovered by the first and second skirts.

4. The incision closure apparatus of claim 2, wherein the first and second skirts extend laterally inwardly for covering the incision or wound.

5. The incision closure apparatus of claim 1, wherein the at least one skirt is at least partially transparent.

6. The incision closure apparatus of claim 1, wherein the at least one skirt comprises a stretchable material.

7. The incision closure apparatus of claim 6, wherein the stretchable material comprises one or more of rubber, latex, urethane, polyurethane, silicone, or a thermoplastic elastomer.

8. The incision closure apparatus of claim 1, wherein a thickness of the at least one skirt at or near an outer lateral edge of the at least one skirt is less than a thickness of the first or second base panel at or near an inner lateral edge of the at least one skirt for providing one or more of increased compliance or reduced adhesion loss at least at the outer lateral edge of the at least one skirt.

9. The incision closure apparatus of claim 1, further comprising first and second pluralities of longitudinally spaced-apart supports coupled to the upper surface of the first and second base panels, respectively, each lateral tie having a first end coupled to a first support of the first plurality of longitudinally spaced apart supports on the first base panel and a second end coupled to a second support of the second plurality of longitudinally spaced apart supports on the second base panel.

10. The incision closure apparatus of claim 9, wherein one or more of the first or second plurality of longitudinally spaced-apart supports comprise force distribution structures.

11. The incision closure apparatus of claim 9, wherein the composite structure further comprises the first and second pluralities of longitudinally spaced apart supports.

12. The incision closure apparatus of claim 9, wherein the first and second pluralities of longitudinally spaced apart supports and the lateral ties are less elastic than the first and second base panels and the at least one skirt.

13. The incision closure apparatus of claim 9, wherein the supports comprise flexible, non-distensible materials.

14. The incision closure apparatus of claim 9, wherein the supports are embedded in or laminated to the upper surface of each panel.

15. The incision closure apparatus of claim 9, wherein one or more of the supports are C-shaped.

16. The incision closure apparatus of claim 15, wherein the one or more C-shaped supports comprises a longitudinal portion for limiting longitudinal expansion of the first or second base panel at the support and a lateral portion for limiting lateral expansion of the first or second base panel at the support.

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

18. The incision closure apparatus of claim 17, 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).

19. The incision closure apparatus of claim 18, 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.

20. 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.

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

22. The incision closure apparatus of claim 1, wherein the at least one skirt, first base panel, and second base panel have outer lateral edges, and wherein the outer lateral edge of one or more of the at least one skirt, first base panel, or second base panel is wavy to reduce its tension per unit length.
