Abstract
Abstract An apparatus for radiating high intensity energy at a subject for treating diseases such as rheumatoid or psoriatic arthritis and a method for using the same. A radiation source generating radiation at a predetermined output wavelength transilluminates affected tissues of the subject for a predetermined duration. The radiation source has sufficient intensity and is applied for sufficient duration to photolyze disease-specific antigens within the transilluminated tissues responsible for evoking complex immune response, thus reducing inflammation and disease progression.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
75 words
A method of treating rheumatoid and psoriatic arthritic inflammation on the body of a subject, the method comprising the steps of: providing a radiation source having an output wavelength bandwidth between 640 nanometers and 800 nanometers; and irradiation said output at the epidermis of the subject to transilluminate the arthritic joint with an incident power in the range of 40 to 200 milliwatts per square centimeter for a time sufficient to provide an effective treatment.
Claim 2
Independent Claim
75 words
A method of treating rheumatoid and psoriatic arthritic inflammation on the body of a subject, the method comprising the steps of: providing a radiation source having an output wavelength bandwidth between 640 nanometers and 800 nanometers; and irradiation said output at the epidermis of the subject to transilluminate the arthritic joint with an incident power in the range of 40 to 200 milliwatts per square centimeter for a time sufficient to provide an effective treatment.
Claim 3
Dependent Claim
38 words
The method of treating arthritic inflammation as recited in claim 1 further comprising the step of facilitating penetration of the radiation by coating the target epidermis with mineral oil prior to directing the radiation source at the subject.
Claim 4
Dependent Claim
32 words
The method of treating arthritic inflammation as recited in claim 1 further comprising the step of preventing thermal damage to the epidermis by directing airflow to the irradiated area of the epidermis.
Claim 5
Independent Claim
131 words
A method of treating rheumatoid and psoriatic arthritic inflammation on the body of a subject, the method comprising the steps of: providing a radiation source that produces a converging beam with wavelengths having a bandwidth in the range of 640 to 800 nanometers; converting the beam; filtering all wavelengths outside the wavelength bandwidth while the beam is converging then diverging; directing the filtered radiation at the epidermis of the subject adjacent the arthritic inflammation; and reducing the arthritic inflammation by maintaining the radiation output at an incident power on the order of between about 40 to 200 milliwatts per square centimeter for a time sufficient to provide an effective treatment but not to exceed 100 joules per square centimeter when the output of the radiation source transilluminates the affected soft tissues.
Claim 6
Independent Claim
131 words
A method of treating rheumatoid and psoriatic arthritic inflammation on the body of a subject, the method comprising the steps of: providing a radiation source that produces a converging beam with wavelengths having a bandwidth in the range of 640 to 800 nanometers; converting the beam; filtering all wavelengths outside the wavelength bandwidth while the beam is converging then diverging; directing the filtered radiation at the epidermis of the subject adjacent the arthritic inflammation; and reducing the arthritic inflammation by maintaining the radiation output at an incident power on the order of between about 40 to 200 milliwatts per square centimeter for a time sufficient to provide an effective treatment but not to exceed 100 joules per square centimeter when the output of the radiation source transilluminates the affected soft tissues.
