Abstract:
A wound closure system for closing a wound on a patient, comprising:an elongated flexible backing strip having opposite ends, first and second surfaces facing away from one another and a length and width sufficient to secure facing edges of the wound in close juxtaposition to one another, said backing strip comprising a first portion disposed between said ends and adapted to overlie the facing edges of said wound, and second and third portions disposed on either side of said first portion and each provided with a predetermined number of spaced-apart perforations extending through said backing strip from said first surface to said second surface, said first portion being free of any aperture extending through said backing strip from said first surface to said second surface; a first pressure-sensitive adhesive coated on at least part of the first surface of said backing strip including said second and third portions thereof, to adhere at least said second and third portions of said backing strip to the patient with the facing edges of said wound in said close juxtaposition; a first protective member removably attached to said backing strip and covering said pressure-sensitive adhesive; and a flowable, moisture-curable surgical adhesive for application into said perforations to strengthen the adhesion of said second and third portions of said backing strip to the patient; whereby after (a) removal of said protective member to expose said pressure-sensitive adhesive, (b) application of said backing strip with the exposed pressure-sensitive adhesive onto said patient to secure the facing edges of said wound in said close juxtaposition, and (c) application of said surgical adhesive into said apertures, said surgical adhesive flows through said perforations and upon curing forms discrete bonding sites cooperating with said backing strip to maintain the facing edges of said wound in said close juxtaposition without the cured adhesive adversely affecting the flexibility of said backing strip, wherein a second protective member having a second pressure-sensitive adhesive coated on one side thereof is removably attached to said backing strip and covers said second surface, said strip being disposed between said first and second protective members, and wherein said second protective member is provided with a corresponding number of perforations registering with the perforations defined in said second and third portions of said backing strip, and being in flow communication therewith.
