Abstract

Deep Tissue Low Intensity Laser Therapy or Treatment (DT-LILT) as described here is a novel methodology through which selective destruction of nociceptive (pain) nerves can be brought upon by a medical laser delivery system using the phenomenon of absorption and cell resonance. Using this method nerve cells that transmit pain can be selectively destroyed leaving the surrounding tissues intact as no heat is generated. The delivery system incorporates a fine needle through which a 703 nm (range 690 to 710) pulsed wave low intensity laser is delivered deep into the body, directly to the area of pain causing selective destruction of pain nerves. Laser devices based on this methodology should be used only by the physician or equivalent professional community since diagnosing and defining the area of pain is critical to providing successful pain relief.

Claims

1. A method of laser therapy in the treatment of pain conditions by selective destruction of nociceptive or pain nerves, comprising the steps of:

a. A laser generator that generates pulsed wavelength laser which is transmitted fiberoptically through a laser fiber and

b. Attaching the laser fiber to a spinal needle and

c. Using the spinal needle with the attached laser fiber to contact the area where pain nerves require destruction,

Whereby, the pulsed laser with the wavelength as above is able to destroy the pain nerves on contact without affecting the other types of nerves or surrounding tissues.

2. The method as described in claim 1 further comprising the step of laser wavelength to be 700 nm to 705 nm with a range between 690 nm to 710 nm for optimal absorption of laser energy by pain nerves.

3. The method as described in claims 1 and 2 further comprising the step of pulsation of the above laser wavelength to cause cell resonance within the pain nerves promoting self destruction.

4. The method as described in claims 1, 2 and 3 further comprising the step which has the optimal average output power of laser to be 4 mW to 6 mW which is limited and adjustable within a range between 1 mW to 6 mW, whereby heat generation is prevented through low energy laser outputs, preserving the integrity of non pain nerves and surrounding tissues.

5. The method as described in claim 1 further comprising the step of attaching the laser fiber to a spinal needle by:

a. Using a luer lock mechanism.

b. Making the laser fiber and the spinal needle as one non detachable unit.

Whereby movement and displacement of the laser fiber within and out of the spinal needle is prevented during treatment sessions consisting of insertion, contact, laser delivery and removal of the spinal needle and the laser fiber.

6. The method as described in claims 1, 2, 3, 4, 5 further comprising the step of limiting laser delivery through timer control.

7. The method as described in claims 1, 2, 3, 4, 5 and 6 wherein the said steps are guided by clinical diagnosis, fluoroscopy and related techniques for identifying the treatment area.

8. The method as described in claims 1, 2, 3, 4, 5, 6 and 7 wherein the said steps are guided by following specific patterns of laser contact and laser delivery for treating pain due to spinal facet joints whereby optimal pain relief is produced.
