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.

Abstract: The present invention relates to a stent using wirelessly transmitted power, and to an external driving device thereof. To this end, a stent is provided with: a power receiving part wirelessly receiving power from the outside; a power storing part storing the power; a second communicating part receiving a control command from the outside; an electrical stimulation part generating electrical stimulation by using the power; a photosensitizer coated onto a stent; an LED illuminating the vicinity of the stent; and a second control part controlling the heat-generating stent on the basis of the control command.
