Systems and Methods for Closing a Tissue Opening
First Claim
1. A method of non-invasively closing a tissue opening, the method comprising:
- affixing to the skin an assembled pair of substantially identical closure components so that the assembled pair is affixed to the skin in a manner so that each of the closure components is disposed on an opposite side of the tissue opening, each component having;
a strip with a preapplied adhesive layer on a first side thereof to affix the attachment strip to the skin;
an assembly mounted on a second side of the strip;
a toothed pull-tab coupled to the strip through the assembly and defining a longitudinal axis, the assembly having a forward face to which the pull-tab is affixed and an opposed rearward face, the forward face including a sloped portion that is sloped rearward as it approaches the strip; and
a female connective element mounted on the second side of the strip and built into the assembly for receiving and releasably engaging a pull-tab from the other component and into which the pull-tab from the other component has been placed,wherein each pull tab has a length sufficient to reach and be received by the female connective element of the other closure component; and
drawing the pull tab of each closure component through the female connective element of the other component, so as to close the opening non-invasively while causing substantial contact of the sloped portions of the forward faces of the components with one another and reliably introducing eversion of tissue edges that defined the opening, when each assembly pivots about a location of contact of each forward face thus causing lifting of the forward faces resulting in upward traction of the tissue edges.

Abstract
The present invention is directed to tissue closure devices for closing a tissue opening, including one or more closure components, each closure component having a first member and a second member, each of the first and second members having a first surface that adheres to a tissue surface proximate to the tissue opening, each of the first and second members having a second surface substantially orthogonal to the first surface, and each of the first and second members having a transitional region between the first surface and the second surface which is contoured to evert an edge of the tissue opening upon the drawing together of the first and second members. The present invention is also directed to systems and kits, dressing systems, and methods for tissue repair and closure.
