Abstract

An article useful for atraumatic care and/or closure of wounds, as well as for repairing torn or ripped fabric is provided. The article comprises a substrate having opposing first and second major surfaces, a plurality of raised anchoring members disposed across the first major surface, and an optional adhesive pre-mounted adjacent the second major surface. A separate adhesive could also be used to mount the article to the desired underlying surface to be repaired. The substrate is a flexible and conformal continuous web that can be cut into pieces to custom fit the wound or fabric opening. Using the anchoring members and a thread, the pieces can be drawn together to correspondingly draw the tissue or fabric on either side(s) of the opening together, thereby closing the opening without piercing or suturing/sewing together the underlying tissue or fabric. Methods for the atraumatic care and/or closure of wounds, as well as for repairing torn or ripped fabric are also provided, including kits to facilitate the same.

Claims

1. An article for the atraumatic care and/or closure of a wound or closure of ripped or torn fabric, said article comprising:

a substrate having opposing first and second major surfaces;

a plurality of raised anchoring members disposed across said first major surface; and

an optional adhesive adjacent said second major surface.

2. The article of claim 1, wherein said substrate is a continuous, flexible web, comprising a pair of laterally spaced longitudinal side edges and a pair of laterally spaced transverse ends.

5. The article of claim 1, wherein said substrate is severable.

6. The article of claim 1, wherein said substrate comprises a woven or nonwoven web of cotton, silk, hemp, flax, rayon, polyester, acrylic, acrylate, polyolefin, nylon, polyurethane, polyethylene, polyester, wire, and/or embedded wire clothe.

7. The article of claim 1, wherein said anchoring members are selected from the group consisting of loops, half-loops, eyelets, mesh, hooks, pegs, prongs, nubs, generally upright strands of fiber, prone strands of fiber, pleats, and combinations thereof.

8. The article of claim 1, wherein said anchoring members are disposed substantially uniformly across said first major surface.

9. The article of claim 1, wherein said anchoring members project away from said first major surface, and have respective heights, as measured from said first major surface, of from about 1 mm to about 20 mm.

11. The article of claim 1, wherein said adhesive is in the form of a layer adjacent said second major surface, and is selected from the group consisting of pressure sensitive adhesives, heat-activated adhesives, and radiation-activated adhesives.

17. The kit of claim 30, wherein said thread comprises a substantially rigid end portion, or wherein said kit further comprises a needle configured to guide said thread.

20. A method for the atraumatic closure of a tissue wound of a subject, said wound having wound edges, said method comprising:

providing an article according to claim 1 and a thread;

adhering said article substrate to said tissue adjacent said wound edges on a first side of said wound and on a second side of said wound opposite said first side; and

reapproximating said wound edges by;

securing said thread to a first anchoring member on said first side of said wound,

passing said thread to said second side of said wound opposite said first side and securing said thread to a second anchoring member, and

repeating said securing and said passing along the wound edges, said thread being under tension and pulling said tissue from said first side of said wound towards said tissue on said second side of said wound thereby closing said wound.

21. The method of claim 20, wherein said adhering comprises:

applying adhesive to said tissue adjacent said wound edges on a first side of said wound and on a second side of said wound opposite said first side; and

mounting said article substrate to said adhesive with said second major surface being in contact with said adhesive.

22. The method of claim 20, further comprising:

determining the shape of the edges of said wound;

severing said substrate into one or more pieces to conform to said shape, prior to adhering said pieces to tissue adjacent said wound edges.

25. The method of claim 20, wherein the tissue of said subject is not pierced during said reapproximating.

26. The method of claim 20, wherein at least one of said wound edges is inverted, further comprising

securing a thread to an anchoring member proximate to said inverted wound edge;

drawing said thread away from said wound edge; and

securing said thread to an anchoring member distal from said wound edge thereby lifting said inverted wound edge to yield an everted wound edge.

30. A kit for the atraumatic closure of a wound, said kit comprising:

an article according to claim 1,

optionally a thread; and

instructions for using said article and a thread to close a wound.

31. The kit of claim 30, wherein said article does not comprise adhesive adjacent said second major surface, said kit further comprising an adhesive for mounting said article to tissue or fabric.

32. The kit of claim 30, further comprising:

a template for determining the shape of said wound;

a device for cutting said article; and

a first-aid component selected from the group consisting of disinfectant, isopropyl alcohol, antibiotic ointment, betadine, chlorhexidine, and combinations thereof.

35. A method for the atraumatic care of a wound of a subject, said wound having wound edges, said method comprising:

providing an article according to claim 1 and a thread;

adhering said article substrate to said tissue adjacent said wound edges on a first side of said wound and on a second side of said wound opposite said first side;

covering said wound with a dressing; and

securing said dressing to said wound by;

securing said thread to a first anchoring member on said first side of said wound,

passing said thread over said dressing to said second side of said wound opposite said first side and securing said thread to a second anchoring member, and

repeating said securing and said passing over said dressing along the wound edges, said thread being under tension and pressing said dressing towards said wound, thereby securing said dressing to said wound.

42. The method of claim 35, wherein said wound is filled with sterile packing prior to covering said wound with dressing, said method further comprising:

removing said dressing by cutting said thread;

removing said packing from said wound;

re-packing said wound with a sterile packing;

covering said wound with a dressing; and

securing said dressing to said wound by;

securing a thread to a first anchoring member on said first side of said wound,

passing said thread over said dressing to said second side of said wound opposite said first side and securing said thread to a second anchoring member, and

repeating said securing and said passing over said dressing along the wound edges, said thread being under tension and pressing said dressing towards said wound, thereby securing said dressing to said wound.

44. A method for the atraumatic securement of a medical device to a patient'"'"'s tissue, said method comprising:

providing an article according to claim 1 and a thread;

inserting a medical device into said patient;

adhering said article substrate to said tissue adjacent where said device is inserted into said patient on a first side of said device and on a second side of said device opposite said first side;

securing a thread to a first anchoring member on said first side of said device and to said device; and

securing a thread to a second anchoring member on said second side of said device and to said device, wherein said thread on each side of said device is under tension to stabilize and prevent dislodgement of said device from said patient.

46. The method of claim 44, wherein said device is selected from the group consisting of tracheal tubes, nasogastric tubes, ventilators, drains, catheters, IVs, central lines, arterial lines, and combinations thereof.
