Abstract
Abstract A skin closure system includes an elongated bandage provided with a fabric layer formed of relatively thick, pliable material and a support layer formed of relatively thin, stiff material. An intermediate adhesive layer is provided between the support layer and the fabric layer for securing them together, and an exposed adhesive layer is provided on the fabric layer opposite the support layer. An elongated strip of backing material is retained on the exposed adhesive layer of the bandage and is removable from the exposed adhesive layer to allow application of the bandage to the skin.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
A skin closure system comprising: a primary bandage including a fabric layer formed of a first material having a thickness of about 1-5 mils and presenting opposed surfaces, a support layer formed of an elongated strip of a second material, an intermediate adhesive layer between the support layer and one surface of the fabric layer for securing them together, and an exposed adhesive layer on the opposed surface of the fabric layer, the support layer having a thickness less than the thickness of the fabric layer and being inflexible relative to the first material; and an elongated strip of backing material that is retained on the exposed adhesive layer of the primary bandage and is removable from the exposed adhesive layer to allow application of the bandage to the skin.
Claim 2
Dependent Claim
130 words
A skin closure system comprising: a primary bandage including a fabric layer formed of a first material having a thickness of about 1-5 mils and presenting opposed surfaces, a support layer formed of an elongated strip of a second material, an intermediate adhesive layer between the support layer and one surface of the fabric layer for securing them together, and an exposed adhesive layer on the opposed surface of the fabric layer, the support layer having a thickness less than the thickness of the fabric layer and being inflexible relative to the first material; and an elongated strip of backing material that is retained on the exposed adhesive layer of the primary bandage and is removable from the exposed adhesive layer to allow application of the bandage to the skin.
Claim 3
Dependent Claim
22 words
A skin closure system as recited in claim 1, wherein the fabric layer is a netting formed of high density polyethylene (HDPE).
Claim 4
Dependent Claim
18 words
A skin closure system as recited in claim 2, wherein the fabric layer is about 4.4 mils thick.
Claim 5
Dependent Claim
27 words
A skin closure system as recited in claim 1, wherein the support layer is a film of polyurethane having a thickness of about 1 mil or less.
Claim 6
Dependent Claim
23 words
A skin closure system as recited in claim 1, wherein the intermediate and exposed adhesive layers are formed of a nonsensitizing acrylic copolymer.
Claim 7
Dependent Claim
35 words
A skin closure system as recited in claim 1, wherein the backing material is kraft, and is provided with a coating of silicone which permits the kraft to be removed from the exposed adhesive layer.
Claim 8
Dependent Claim
166 words
A skin closure system as recited in claim 1, further comprising a secondary bandage which also includes a fabric layer formed of an elongated strip of relatively thick, pliable material presenting opposed surfaces, a support layer formed of an elongated strip of relatively thin, stiff material, an intermediate adhesive layer between the support layer and one surface of the fabric layer for securing them together, and an exposed adhesive layer on the opposed surface of the fabric layer; and a pair of elongated strips of backing material which are retained beside one another on the exposed adhesive layer of the secondary bandage and are independently removable from the secondary bandage so that one of the strips of backing material may be removed to allow application of the secondary bandage across from the primary bandage along the skin to be closed, and the other strip may then be removed to allow the secondary bandage to be adhered to the primary bandage across the skin to be closed.
Claim 9
Dependent Claim
58 words
A skin closure system as recited in claim 1, wherein the primary bandage includes a generally centrally located, longitudinally extending ridge defining a concave channel in the exposed adhesive layer, the strip of backing material being retained on the exposed adhesive layer of the primary bandage on both lateral sides of the channel but not within the channel.
Claim 10
Dependent Claim
15 words
A skin closure system as recited in claim 1, wherein the primary bandage is transparent.
