Abstract
The present invention provides a device and method for a laser treatment that couples surgical or activating laser power with a biomodulating power to enhance proper tissue healing and regeneration after treatment. This treatment is achieved using an optical fiber system delivering laser power from two separate laser sources. One source provides laser energy at a power level and density suitable for the surgical or activation action desired. The second source produces laser power at a wavelength suitable for producing biomodulating effects in the treated tissue. Biomodulation treatment of the tissue promotes cellular healing and regeneration and ensures that proper healing occurs. In addition, the present invention describes a method by which the device is used for treatment. The surgical or activating laser energy is applied to a site as the device is passed over the treatment area. During this treatment, the device also emits a biomodulating treatment beam onto the site over which the first beam has already passed. The device in this manner systematically performs a surgical or activation action and then follows immediately with a healing action, enhancing the success of the trea…
