One embodiment is directed to a system for altering the function of a sensory unit that innervates a targeted tissue region in an animal, the sensory unit being configured to express a light-responsive protein, comprising a light delivery element configured to direct radiation to at least a portion of a targeted tissue structure; and a light source configured to provide light to the light delivery element; wherein the targeted tissue structure is illuminated transcutaneously with radiation such that a membrane potential of cells comprising the targeted tissue structure is modulated at least in part due to exposure of the light-responsive protein to the radiation.

A method for treating pelvic pain and or chronic prostatitis, and or overactive bladder symptoms. Energy, preferably in the form of infrared or near infrared wavelength light may be applied across the vaginal tissue or rectal tissue to treat pelvic pain and or chronic prostatitis. This method of energy application may cause local heating, alteration of cellular respiration, and alterations of local blood flow resulting in decreased muscle spasm, and or decreased pain, and or decreased overactive bladder symptoms. The method of the present invention may effectively treat chronic pelvic pain and or the symptoms of chronic prostatitis. The method of the invention may combine massaging of tissue with irradiation of same.

Methods, systems, and devices for integrated photo-responsive contouring treatment are described. Methods include identifying a region of skin corresponding to a contouring treatment of the skin. The region of skin may be provided with a photo-responsive material overlying a portion of the region of the skin. Methods may include identifying one or more treatment regions overlapping the photo-responsive material. The treatment regions may be identified at least in part to apply the contouring treatment. Methods may include determining an irradiation profile for each of the one or more treatment regions to contour each respective treatment region as part of applying the contouring treatment. Methods may also include irradiating the photo-responsive material at the one or more treatment regions in accordance with the respective irradiation profiles. Irradiating the photo-responsive material may induce a localized change in shape of the photo-responsive material in the respective treatment regions.

In one or more embodiments, an apparatus comprises a housing, an emitter, and an electronic circuit. The housing is configured to fit within a patient's mouth. The emitter is at least partially encased within the housing. The emitter is configured to emit an effective amount of light to the alveolar soft tissue when the housing is disposed within the mouth. The electronic circuit is operatively coupled to the emitter. The electronic circuit is configured to control the emitter when the housing is disposed within the mouth and the apparatus is in use during orthodontic treatment. The apparatus and its use for regulating tooth movement or maintaining or improving oral tissue health are disclosed herein.

A method is provided for treating a plaque-based arterial occlusion in a carotid artery of a subject. The method includes performing a carotid endarterectomy on the subject; determining the levels in the subject of a plurality of biomarkers B.sub.i[B.sub.1, . . . , B.sub.n], wherein n 2; and performing light therapy on the subject if any of the plurality of biomarkers B.sub.i has a level x.sub.i in excess of a corresponding threshold value t.sub.i.
