Abstract
Present invention discloses methods and devices for treating skin and nail infections such as onychomycosis and dermatophytosis, caused by pathogenic microbes such as fungi. in a preferred embodiment, a method for treating skin and nail infections comprises irradiating the treatment site with a light radiation source operating at one or more near infrared wavelengths which are absorbed by the pathogenic microbes, specifically operating at 980±30 nm, 1470±40 nm and/or 1900±60 nm. In another preferred embodiment, a method for treating skin and nail fungus comprises irradiating the treatment site with a device emitting laser radiation of 980±30 nm wavelength. In another embodiment, a device for treating toenail fungus comprises a laser radiation source which emits a combination of radiation wavelengths at about 980±30 nm and 1470±40 nm; or 980±30 nm and 1900±60 nm; or 1470±40 nm and 1900±60 nm; or 980±30 nm, 1470±40 nm and 1900±60 nm. In another embodiment, devices for treating skin and nail infections include a laser radiation source and delivery apparatuses such as brush or toothed comb for nail and scalp infections respectively.
