## Abstract

The present invention provides a wound dressing comprising a tessellated water-soluble molding matrix comprised of a polymer selected from the group consisting of polyvinyl alcohol, gelatin, and mixtures thereof and a 1,1-disubstituted ethylene monomer. The present invention further provides methods of using the wound dressing and kits containing the wound dressing.

## Claims

### Claim at position 1

1-5. (canceled)

### Claim 6

A method of treating a wound comprising:
(1) applying a 1,1-disubstituted monomer to a wound and embedding a tessellated water-soluble molding matrix comprised of a polymer selected from the group consisting of polyvinyl alcohol, gelatin, and mixtures thereof in said 1,1-disubstituted ethylene monome;
(2) polymerizing the 1,1-disubstituted ethylene monomer; and
(3) dissolving said water-soluble molding matrix leaving a molded polymer applied to said wound.

### Claim 7 (depends on 6)

The method of claim 6 wherein said 1,1-disubstituted ethylene monomer comprises a cyanoacrylate.

### Claim 8 (depends on 6, 7)

The method of claim 7 wherein said cyanoacrylate is selected from the group consisting of ethyl cyanoacrylate, n-butyl cyanoacrylate, 2-octyl cyanoacrylate, methoxyethyl cyanoacrylate, ethoxyethyl cyanoacrylate, dodecyl cyanoacrylate, 2-ethylhexyl cyanoacrylate, butyl cyanoacrylate, 3-methoxybutyl cyanoacrylate, 2-butoxyethyl cyanoacrylate, 2-isopropoxyethyl cyanoacrylate, 1-methoxy-2-propyl cyanoacrylate, hexyl cyanoacrylate, butyl lactoyl cyanoacrylate, butyl glycolcyl cyanoacrylate, ethyl lactoyl cyanoacrylate, and ethyl glycoloyl cyanoacrylate. method of claim 6 wherein the tessellated water-soluble molding matrix is comprised of cells measuring less than about 5 mm in any given dimension.

### Claim 10 (depends on 6)

The wound dressing of claim 6 wherein the tessellated water-soluble molding matrix is comprised of cells measuring less than about 3 mm in any given dimension.

### Claim at position 6

11-15. (canceled)

### Claim 16

A method of treating a wound comprising:
(1) applying a tessellated water-soluble molding matrix comprised of a polymer selected from the group consisting of polyvinyl alcohol, gelatin, and mixtures thereof to a wound and applying a 1,1-disubstituted ethylene monomer to the wound filling at least a portion of at least one cell of the water-soluble molding matrix;
(2) polymerizing the 1,1-disubstituted ethylene monomer; and
(3) dissolving said water-soluble molding matrix leaving a molded polymer applied to said wound.

### Claim 17 (depends on 16)

The method of claim 16 wherein said 1,1-disubstituted ethylene monomer comprises a cyanoacrylate.

### Claim 18 (depends on 17)

The method of claim 17 wherein said cyanoacrylate is selected from the group consisting of ethyl cyanoacrylate, n-butyl cyanoacrylate, 2-octyl cyanoacrylate, methoxyethyl cyanoacrylate, ethoxyethyl cyanoacrylate, dodecyl cyanoacrylate, 2-ethylhexyl cyanoacrylate, butyl cyanoacrylate, 3-methoxybutyl cyanoacrylate, 2-butoxyethyl cyanoacrylate, 2-isopropoxyethyl cyanoacrylate, 1-methoxy-2-propyl cyanoacrylate, hexyl cyanoacrylate, butyl lactoyl cyanoacrylate, butyl glycolcyl cyanoacrylate, ethyl lactoyl cyanoacrylate, and ethyl glycoloyl cyanoacrylate.

### Claim 19 (depends on 16)

The method of claim 16 wherein the tessellated water-soluble molding matrix is comprised of cells measuring less than about 5 mm in any given dimension.

### Claim 20 (depends on 16)
