Abstract

A method and combination for performing laser therapy, involving the steps of providing a sheet of clear film of appropriate size and thickness, and placing the sheet of clear film over an area of a skin to be treated prior to laser therapy. The method may further include steps of replacing the sheet with a new sheet of clear film, periodically during the therapy.

Claims

1. In combination:

a laser device having a contact surface, for performing laser treatment of an area of a surface of a patient; and

a protecting/cooling article of a substantially transparent gel film sheet which is cut to an appropriate size for covering said area of said surface of said patient, which gel is not a liquid gel material;

the gel film sheet for positioning between the laser device contact surface and said surface of said patient to be treated;

wherein the gel film sheet is for applying to said area of said surface of said patient to be treated prior to performing laser treatment to said area;

wherein laser treatment is performed to said area by passing a laser beam from said laser device to said surface of said patient through said gel film sheet without substantial attenuation of said laser beam when transmitted through said gel film sheet;

wherein said gel film sheet, when applied to said surface of said patient to be treated, provides cooling of said surface of said patient during laser treatment; and

wherein said gel film sheet protects said contact surface of said laser device during said laser treatment.

2. The combination of claim 1, wherein said laser device is a photothermolysis laser (PTL) device.

3. The combination of claim 1, wherein said transparent gel film sheet is a hydrophilic, organic transparent gel.

4. The combination of claim 1, wherein said substantially transparent gel film sheet is a polyacrylamide agar moist gel.

5. The combination of claim 1, wherein said gel film sheet has a thickness in a range of approximately 0.1-25 mm.

6. The combination of claim 1, wherein said substantially transparent gel film sheet has a thickness in a range of approximately 0.5-10 mm.

7. The combination of claim 1, wherein said substantially transparent gel film sheet has a thickness in a range of approximately 1-5 mm.

8. The combination of claim 5, wherein said substantially transparent gel film is a polyacrylamide agar moist gel.

9. The combination of claim 6, wherein said substantially transparent gel film is a polyacrylamide agar moist gel.

10. The combination of claim 1, wherein said protecting/cooling article consists essentially of said substantially transparent gel film sheet.

11. In combination:

a laser device having a contact surface, for performing laser treatment of an area of a skin surface of a patient; and

a protecting/cooling article of a substantially transparent gel film sheet which is cut to an appropriate size for covering said area of said skin surface of said patient, which gel is not a liquid gel material;

the gel film sheet for positioning between the laser device contact surface and said skin surface of said patient to be treated;

wherein the gel film sheet is for applying to said area of said skin surface of said patient to be treated prior to performing laser treatment to said area;

wherein laser treatment is performed to said area by passing a laser beam from said laser device to said skin surface of said patient through said gel film sheet without substantial attenuation of said laser beam when transmitted through said gel film sheet;

wherein said gel film sheet, when applied to said skin surface of said patient to be treated, provides cooling of said skin surface of said patient during laser treatment; and

wherein said gel film sheet protects said contact surface of said laser device during said laser treatment.

12. The combination of claim 11, wherein said laser device is a photothermolysis laser (PTL) device.

13. The combination of claim 11, wherein said transparent gel film sheet is a hydrophilic, organic transparent gel.

14. The combination of claim 11, wherein said substantially transparent gel film sheet is a polyacrylamide agar moist gel.

15. The combination of claim 11, wherein said gel film sheet has a thickness in a range of approximately 0.1-25 mm.

16. The combination of claim 11, wherein said substantially transparent gel film sheet has a thickness in a range of approximately 0.5-10 mm.

17. The combination of claim 11, wherein said substantially transparent gel film sheet has a thickness in a range of approximately 1-5 mm.

18. The combination of claim 15, wherein said substantially transparent gel film is a polyacrylamide agar moist gel.

19. The combination of claim 16, wherein said substantially transparent gel film is a polyacrylamide agar moist gel.

20. The combination of claim 11, wherein said protecting/cooling article consists essentially of said substantially transparent gel film sheet.
