Abstract

A method of treating infected tissue with topical nitric oxide exposure includes the steps of providing a source of nitric oxide containing gas and delivering the nitric oxide containing gas to a skin surface containing infected tissue so as to bathe the infected tissue with nitric oxide.

Claims

1. A method of treating infected tissue with topical nitric oxide exposure comprising the steps of:

providing a source of nitric oxide containing gas; and

delivering the nitric oxide containing gas to a skin surface containing infected tissue so as to bathe the infected tissue with nitric oxide.

2. The method of claim 1, wherein the nitric oxide is delivered to the skin surface using a bathing unit surrounding the infected tissue.

3. The method of claim 1, wherein the concentration of nitric oxide in the nitric oxide containing gas that bathes the infected tissue is less than about 200 ppm.

4. The method of claim 1, further comprising the step of refreshing the infected tissue with a fresh supply of nitric oxide containing gas.

5. The method of claim 1, wherein a jet of nitric oxide containing gas is delivered to the portion of the skin surface containing the infected tissue.

6. The method of claim 1, wherein the source of nitric oxide containing gas is a pressurized cylinder containing nitric oxide gas.

7. The method of claim 1, further comprising the step of monitoring the concentration of nitric oxide bathing the infected tissue.

8. The method of claim 1, further comprising the step of monitoring the concentration of nitrogen dioxide bathing the infected tissue.

9. The method of claim 1, further comprising the step of evacuating the nitric oxide containing gas from the area surrounding the infected tissue.

10. The method of claim 9, further comprising the step of stripping nitric oxide from the evacuated gas.

11. The method of claim 9, further comprising the step of stripping nitrogen dioxide from the evacuated gas.
