Abstract
A multi-barbed apparatus is provided, and methods of use, for penetrating two sides of a wound and holding the edges in apposition. The apparatus may be inserted within a wound or underneath the skin, and mechanically adheres the two sides of the wound together. The apparatus includes a biocompatible substrate carrying a multiplicity of tissue penetrating barbs on a least one side thereof, and may be formed as a rigid or flexible sheet, tube or other shape.
