Abstract

The present invention includes a first and a second interlaced component, each having a permeable adhesive-backed wound edge pad for attachment to the skin of a patient adjacent to a laceration or incision to be closed. Each of the permeable wound edge pads is attached to an opposing tension adjusting pad that also has an adhesive backing. The wound edge pads are connected to the respective tension adjusting pads by elongate connecting elements that may be flat or tubular in shape. The present invention also includes an adhesive that may be applied in liquid form to the permeable wound edge pads. Adhesion of the adhesive on and within the permeable wound edge pads seals the wound site and adds structural rigidity to the interlaced components.
