Abstract
A light-emitting treatment device including one or more light-emitting elements disposed in a flexible and stretchable pad (or a body-conforming shaped article) defining a skin- or tissue-adhering surface having an inherently tacky characteristic for secure application to the skin, tissue, or other external or internal regions of the patient's body. The light-emitting treatment device is configured to contact and adhere to the skin or tissue of a patient, and irradiate an underlying region for photodynamic therapy. The treatment device may be fabricated from a shell member and a filler material (such as a molded silicone rubber shell member and a silicone gel filler material), to provide a skin-adhering, peelable, washable, and repositionable contact surface.
