Abstract: A phototherapy device is provided for treating a medical condition by delivering phototherapy using a pad and a light source supported by the pad. The light source includes multiple light emitters that are located at different positions on the pad and that emit treatment electromagnetic radiation. A treatment property of the phototherapy varies spatially based on medical properties of the anatomical treatment area.

Abstract: An intraoral phototherapy device is provided that improves tissue illumination. Oral tissue illumination is particularly difficult inside of the teeth. That is, it is particularly difficult to illuminate the roof of the mouth, floor of the mouth, sides of the tongue, and/or ventral surface of the tongue. The intraoral phototherapy device improves illumination of these tissues using a bifurcated central projection that receives a portion of the tongue. An intraoral phototherapy device is also provided that includes a breathing tube to improve patient breathing and vocalization for enabling illumination of tissues at the back of the mouth. An intraoral phototherapy device is additionally provided that allows for separate control of light emission from different areas of the intraoral phototherapy device.
