Abstract

The present invention is directed to using cryogenic compositions, which are non-toxic, non-flammable, and have desirable ozone depletion and global warming potential, for cooling heated skin during skin treatments with a skin treatment apparatus.

Claims (13)

1. A method for cooling skin tissue comprising:

using a cryogenic composition in a skin treatment apparatus to cool heated skin during skin treatments, the cryogenic composition including

propyne in combination with one or more of the following: 1,1,3,3,3-pentafluoropropene, 1,2,3,3,3-pentafluoropropene, or trifluoroiodomethane.

2. The method of claim 1 wherein the cryogenic composition is a mixture of trifluoroiodomethane and propyne, with trifluoroiodomethane being present in an amount of about 97% to about 99% by weight of the composition.

3. The method of claim 1 wherein using a cryogenic composition in a skin treatment apparatus to cool heated skin during skin treatments comprises:

positioning an electrode of the skin treatment apparatus adjacent a skin surface, the skin treatment apparatus adapted to deliver energy via the electrode to tissue located beneath the skin surface;

applying energy to tissue located beneath the skin surface via the electrode; and

spraying the cryogenic composition against a non-patient side of the electrode to cool the tissue.

4. The method of claim 3 further including detecting a temperature of the electrode.

5. The method of claim 1 wherein the cryogenic composition is propyne in combination with 1,1,3,3,3-pentafluoropropene, 1,2,3,3,3-pentafluoropropene, or trifluoroiodomethane.

6. The method of claim 1 wherein the cryogenic composition is propyne in combination with 1,1,3,3,3-pentafluoropropene.

7. The method of claim 1 wherein the cryogenic composition is propyne in combination with 1,2,3,3,3-pentafluoropropene.

8. The method of claim 1 wherein the cryogenic composition is propyne in combination with trifluoroiodomethane.
