Abstract

Disclosed is a bandage for closing a wound or incision, and methods for the use of same. The bandage comprises a first flat flexible component having adhesive on a lower surface and one or more first elongated connectors extending in an offset manner from one edge thereof in a first direction. The bandage further comprises a second flat flexible component having adhesive on a lower surface and one or more second elongated connectors extending in an offset manner from one edge thereof in a second direction generally opposite to the first direction. Pulling elements are joined to the first and second elongated connectors. Means are provided for attaching the first elongated connectors to the second flat flexible component and the second elongated connectors to the first flat flexible component.

Claims

1. A two-component medical device comprising:

a) a first component comprising a first flat flexible component and a plurality of first elongated connectors extending from one edge thereof in a first direction;

b) a second component comprising a second flat flexible component having one or more second elongated connectors extending from one edge thereof in a second direction generally opposite to the first direction wherein the plurality of first elongated connectors and the one or more second elongated connectors are interleaved;

c) a first pulling element joined to said plurality of first elongated connectors and adapted for lateral translation of the first flat flexible component toward a wound edge, the first pulling element having adhesive on a lower surface and wherein the first pulling element is rigid;

d) a second pulling element joined to said one or more second elongated connectors and adapted for lateral translation of the second flat flexible component toward the wound edge, the second pulling element having adhesive on a lower surface and wherein the second pulling element is rigid; and

e) means for attaching the plurality of first elongated connectors to the second flat flexible component and means for attaching the one or more second elongated connectors to the first flat flexible component such that the plurality of first elongated connectors and the one or more second elongated connectors are sufficiently spaced apart to facilitate fine adjustment of the first flat flexible component relative to the second flat flexible component for substantially parallel alignment of the edge of the first flat flexible component with the edge of the second flat flexible component during closure of the wound or incision.

2. The medical device of claim 1 wherein elements a)-d) are produced from a substantially inelastic material or are produced from an elastic material which is reinforced with an inelastic structural component thereby rendering the device substantially inelastic.

3. The medical device of claim 1 wherein the first and second pulling elements are capable of being removed following attachment of the bandage.

4. The medical device of claim 1 wherein the first elongated connectors are adjacent to one another and centrally located, and the second elongated connectors flank the first elongated connectors at outside edges of the bandage.

5. The medical device of claim 1 wherein the first and second pulling elements are non-rigid, but are reinforced with a rigid element.

6. The medical device of claim 1 wherein the edges of the first and second flat flexible components which attach to the skin on opposing sides of a wound or incision are capable of everting skin edges to promote wound healing.

7. The medical device of claim 1 wherein the edges of the first and second flat flexible components are angled or curved to evert the skin edges.

8. The medical device of claim 1 wherein a portion of the elongated connector is cut away to increase unobstructed surface area above the wound thereby facilitating drainage of exudates and application of medication.

9. The medical device of claim 1 wherein the first and second flat flexible components are adapted for wound closure alignment.

10. The medical device of claim 9 wherein said adaptation comprises alignment marks on the first and second flat flexible components for alignment with each other and/or with marks placed directly on skin.

11. The medical device of claim 1 which is capable of transdermal drug delivery.

12. The medical device of claim 1 further comprising an elastic tension indication element.

13. The medical device of claim 12 wherein the elastic tension indication element is removable with the pulling elements.

14. The medical device of claim 1 further comprising a rigid polymer bar attached to the edges of the first and second flat flexible components which are nearest to and substantially parallel the wound or incision.
