This invention is a diode laser irradiation system (10) for treating biological tissue of a subject without exposing the tissue to damaging thermal effects. The system includes a manipulable wand (14) for contact with the tissue, a diode laser (70) disposed in the wand for irradiating the tissue with coherent optical energy at a power output level of less than one thousand milliwatts, and laser setting controls (24 26) for operating the diode laser , to achieve a rate of absorption and conversion to heat in the irradiated tissue in a range between a minimum rate sufficient to elevate the average temperature of the irradiated tissue to a level above the basal body temperature of the …

Why it's free to use
- Filed March 21, 1997 and granted September 10, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 21, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 21, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
