Abstract

Methods and systems for closing wounds using wound closures and a flowable adhesive skin paint are disclosed. The flowable adhesive does not adhere the wound closures to the skin over the wound to reduce irritation. In some embodiments, the skin paint may include 1-40% of a siloxane-containing polymer; 60-99% of an Alkane-Based Siloxane Polymer Reaction Solvent; and 0-15% of adjuvants. The wound closures used with such a skin paint may include a wound bridging portion of microporous polypropylene film.

Claims

1. A wound closure system comprising:

a quantity of a flowable adhesive skin paint comprising

1-40% of a siloxane-containing polymer;

60-99% of an Alkane-Based Siloxane Polymer Reaction Solvent; and

0-15% of adjuvants; and

at least one wound closure that comprises a backing, a wound bridging portion adapted to be placed over a wound, and a pressure sensitive adhesive, wherein the adhesive skin paint does not adhere the wound bridging portion of the at least one wound closure to skin.

3. A system according to any of claims 1-2, wherein adhesion strength between the wound bridging portion and skin is about 30 grams/centimeter or less.

4. A system according to any of claims 1-2, wherein the wound bridging portion is porous.

5. A system according to any of claims 1-2, wherein the wound bridging portion comprises microporous polypropylene film.

6. A system according to any of claims 1-2, wherein the adhesive skin paint comprises a cyanoacrylate-based adhesive.

7. A system according to any of claims 1-2, wherein the adhesive skin paint comprises a pyroxylin-based adhesive.

8. A system according to claim 1, wherein the at least one wound closure comprises:

opposing elastomeric end portions; and

a wound bridging portion between the end portions;

wherein the wound closure recovers at least 85% after being stretched 30%, and wherein the wound bridging portion stretches less than the end portions when subjected to the same force, whereby the wound bridging portion tends to maintain the wound closed against forces generated by stretching of skin.

9. A system according to claim 8, wherein the wound bridging portion stretches 8% or less when the wound closure stretches 30%.

10. A system according to claim 8, wherein the wound bridging portion stretches 1% or less when the wound closure stretches 30%.

2. A wound closure system comprising:

a quantity of a flowable adhesive skin paint; and

at least one wound closure that comprises a backing, a wound bridging portion adapted to be placed over a wound, and a pressure sensitive adhesive, wherein the adhesive skin paint does not adhere the wound bridging portion of the at least one wound closure to skin; and

wherein the at least one wound closure comprises;

opposing elastomeric end portions; and

the wound bridging portion between the end portions;

wherein the wound closure recovers at least 85% after being stretched 30%, and wherein the wound bridging portion stretches less than the end portions when subjected to the same force, whereby the wound bridging portion tends to maintain the wound closed against forces generated by stretching of skin.
