Wound closure device
First Claim
Patent Images
1. A wound closure device for a wound in a region of skin which defines an epidermal layer and a germinal layer, said device comprising:
- means for defining first and second concave skin contacting surfaces, each presenting a respective concave surface to the epidermal layer;
an adhesive layer covering the first and second skin contacting surfaces and adapted to secure the skin contacting surfaces to the epidermal layer on either side of the wound to cause the epidermal layer to conform to the concave skin contacting surfaces; and
means for holding the first and second skin contacting surfaces in alignment to close the wound, to hold the epidermal layer together in alignment across the wound, and to evert the skin on both sides of the wound to enhance alignment of the germinal layer across the wound and thereby reduce scar tissue formation.

Abstract
A wound closure device includes first and second attachment members, each of which defines a concave skin contacting surface shaped to bond adhesively to the skin on a respective side of a wound. A bridge is provided to hold the two attachment members in abutting alignment to close the wound. The attachment members are sufficiently resilient to evert the skin on both sides of the wound to bring the skin into healing alignment across the wound. In this way, both the epidermis and the germinal layer or dermis of the skin can be aligned properly to minimize scar tissue formation.

6. A wound closure device for a wound in a region of skin, said device comprising:
-
first and second attachment members, each comprising a concave skin contacting surface shaped to bond adhesively to the skin on a respective side of a wound, each of said concave skin contacting surfaces presenting a respective concave surface to the skin; an adhesive layer covering the first and second skin contacting surfaces and adapted to secure the skin contacting surfaces to the skin on either side of the wound to cause the skin to conform to the skin contacting surfaces; and means for releasably aligning and holding the two attachment members together to close the wound; said attachment members being sufficiently resilient to evert the skin on both sides of the wound to bring the skin into healing alignment across the wound. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A wound closure device for a wound in a region of skin, said device comprising:
-
first and second attachment members, each comprising a cylindrically concave skin contacting surface, an array of upstanding spaced, parallel legs connected to an inner longitudinal edge of the skin contacting surface, and a rail extending parallel to the inner longitudinal edge and connected to the legs, said skin contacting surfaces each defining an array of stiffening ribs extending transversely to the inner longitudinal edge and an array of slits, each extending between an adjacent pair of ribs, said skin contacting surfaces each presenting a respective concave surface to the skin; a layer of adhesive on each of the skin contacting surfaces to secure the skin contacting surfaces to the skin on either side of the wound to cause the skin to conform to the skin contacting surfaces; a bridge shaped to slide over the rails of the attachment members to hold the attachment members together with the skin contacting surfaces in alignment to hold the skin together in alignment across the wound, said bridge comprising a top wall which defines an array of spaced apertures and a pair of parallel side walls, each defining an array of spaced openings; said skin contacting surfaces shaped to evert the skin on both sides of the wound when adhesively secured to the skin. - View Dependent Claims (16, 17)
