Light therapy treatment
First Claim
1. A light therapy device comprising:
- a first light source configured to generate light with a first wavelength including 730-770 nm;
a second light source configured to generate light with a second wavelength including 950-970 nm; and
a processor configured to operate the first and second light sources to inhibit cytochrome c oxidase when applied to organic tissue in response to an ischemia-reperfusion event,wherein the first and second wavelengths are applied at a power density that penetrates tissue of a human patient;
wherein the processor is configured to;
reduce a brightness of the light generated to inhibit cytochrome c oxidase following the inset of reperfusion;
reduce the drightness by individually disabling the light sources at different times; and
reduce the brightness by disabling discrete groups of the light sources at different times.

Abstract
An exemplary method includes selecting at least one light source configured to generate light at a particular wavelength and applying the light to tissue following an ischemic event. Applying the light to the tissue inhibits cytochrome c oxidase activity. Another exemplary method includes selecting at least one light source configured to generate light at a particular wavelength and applying the light to tissue following an ischemic event and prior to either reoxygenation of the tissue or clinical intervention to reduce cell damage. An exemplary light therapy device includes at least one light source configured to generate light having a wavelength of at least one of approximately 730-770 nm, 850-890 nm, 880-920 nm, and 930-970 nm.
