This application relates to laser medical devices and its use in pain medicine.
Contents of the provisional patent application Ser. No. 61/122,393 with a Filing Date: Dec. 14, 2008.
Definition of Terms:
1. DT-LILT : Deep Tissue Low Intensity Laser Treatment or Therapy.
2. DT-LIL : Deep Tissue Low Intensity Laser.
3. DT-LILA : Deep Tissue Low Intensity Laser Ablation.
4. DT-LILNA : Deep Tissue Low Intensity Laser Neuroablation.
The use of terms DT-LILT, DT-LIL and DT-LILA are first defined here.
Scientific Concept of DT-LILT: A low intensity laser capable of producing cell resonance within the nerve cell can selectively cause destruction of the nerve cells without affecting the surrounding tissues. The selection of laser wavelength will depend on the absorption characteristics of the nerve cells. Heat may or may not be generated, perhaps not needed as the selective destruction takes place by cell resonance rather than heat coagulation. Use of DT-LILNA is first described here and is different from other medical or tissue lasers whose primary effect is through heat generation.
Delivery System for DT-LILT:
1. Laser Generator capable of generating the appropriate wavelength. Desirable in the 690 nm to 710 nm range. No other medical or tissue laser exists in the world today generating wavelengths between the 690 nm to 710 nm range except as described in this patent.
2. Laser fibers with diameters less than 0.7 and 0.5 mm.
3. Common Quincke Spinal Needle.
4. Laser fiber fixator through luer lock mechanism with the Quincke needle. Such fixation can also be achieved by making the laser fiber and the spinal needle as one non detachable unit.
Ideal Laser Characteristics:
1. Laser Wavelength: 700 nm to 705 nm
2. Laser Output Average Power: 4 mW to 6 mW (range 1 mW to 6 mW)
3. Laser Pulsation, pulsed at nano seconds or picoseconds
4. Laser is Timer controlled: 5 s and 10 s.

Intra-operative Treatment Methodology:
Application: Facet Joint Neuroablation (synonymous medial branch neuroablation). Conventional neuroablation is contingent upon finding the medial branch nerve in an oblique/lateral X ray view and using heat or chemical substance to destroy the medial branch. The method described here is the first to use the simple AP X-ray view and pass laser or DT-LIL to cause the neuroablation DT-LILA or DT-LILNA
Definition of Laser Points: First described here are the laser points for using DT-LILT by use of the above delivery system (as represented in
