Publication number: 20050070976Abstract: An ambulatory device for use in a therapeutic and/or cosmetic treatment, the device comprises an organic light-emitting semiconductor which, in use, covers an area to be treated and emits electromagnetic radiation to cause said therapeutic and/or cosmetic treatment of the area. The light source may be extensive to provide uniform irradiation of the area to be treated and may be pulsed. The device may also include a photopharmaceutical.Type: ApplicationFiled: November 15, 2002Publication date: March 31, 2005Inventors: Ifor David Samuel, James Ferguson
