Abstract
A stent device including a stent coated with a photosensitizer, the stent including a pair of electrodes; and a circuit fixed to the stent, the circuit including a light emitting diode, a power receiving means for wirelessly receiving power from the outside, and converting the power to electric power; a second communicating means for receiving a control command from the outside; and a second control means for applying, based on the control command, the electric power to the electrodes causing an electric current to flow through the stent between the electrodes, the flow causing heating of the stent, and for controlling a temperature of the stent to provide hyperthermia therapy to a tumor, the second control means further for applying, based on the control command, the electric power to the light emitting diode to emit a predetermined wavelength of light to the photosensitizer to provide photodynamic therapy to the tumor.
