Electromagnetic radiation and its therapeutic effect
An electromagnetic radiation therapy system comprising an apparatus that emits electromagnetic radiation centred at or around 1072 nm and configured so as to be placed around a large proportion or the whole of a human or animal body. The invention also includes methods of treating diseases associated with a lack of compliance and or elasticity of vessels such as airway and/or blood vessels.
1. A method of treating chronic obstructive pulmonary diseases associated with a lack of compliance and/or elasticity of an airway within a body cavity, the method comprising treating a superficial area of skin of a chest/thorax abdomen or a whole body of a living human or animal subject by applying to said area divergent electromagnetic radiation having a wavelength centered around 1072 nm having an intensity of at least 500 mW/cm^2 and up to 4 W/cm^2 at the site to be treated, wherein the method is non-invasive, and wherein the radiation penetrates below the superficial area of skin from about 5 mm to 500 mm to tissues and organs within the body cavity and wherein the method does not rely on thermal effects to achieve a therapeutic effect.
2. A method according to claim 1 wherein the superficial area of skin to be treated is irradiated so that the affected tissue within the body cavity receives at least 500-2000 mW/cm 2 peak intensity of radiant energy for at least a minimum of 10-15 microseconds at a repetition rate/frequency of 200-900 Hz and wherein a treatment duration is for at least 30 seconds.
3. A method according to claim 1 wherein divergence of the electromagnetic radiation is in the range 15° to 45° half angled divergent.
4. A method according to claim 1 wherein the electromagnetic radiation centred around 1072 nm has a bandwidth of between 5 to 120 nm.
5. A method according to claim 1 wherein an operating peak output of an electromagnetic radiation source is within 0 to 10 nm of 1072 nm.
6. A method according to claim 1 wherein the electromagnetic radiation is emitted from at least one of solid state light emitting devices, laser diode, solid state light emitting diodes, gas discharge devices and/or light emitting polymers.
7. A method according to claim 1 wherein the electromagnetic radiation centred around 1072 nm has uniform light distribution.
8. A method according to claim 1 wherein the electromagnetic radiation is continuous or pulsed.
9. A method according to claim 1 wherein when the electromagnetic radiation is pulsed, an intensity of the electromagnetic radiation is at least between 500 mW/cm 2 and 2 W/cm 2 peak power and wherein an average intensity is up to 4 W/cm 2 .
10. A method according to claim 1 wherein a treatment area is selected to treat a disease within a body cavity selected from the group consisting of chronic bronchitis and emphysema.
11. A method according to claim 1 , wherein the method is non-invasive.
