PROBLEM TO BE SOLVED: To provide a stent for electrothermal treatment, which prevents electric current from flowing through the inside of the body other than a lesion portion and which is inserted into a stenosed or obstructed lesion portion in a lumen of the body to expand the lesion portion and to apply electric heat to the lesion portion to cauterize the lesion portion.SOLUTION: At least two or more separated bodies 10-1, 10-2 are formed by separating in a longitudinal direction a hollow cylindrical body formed by weaving superelastic shape memory alloy wires 2, the separated bodies being connected with each other through an insulator 20 formed of a flexible material. The separated bodies respectively include power connection lines formed protrudingly by extending the wires to rear sides thereof. When an electricity generator is connected to the power connection lines of the separated bodies, an electric current flows between the separated bodies to generate electric heat by which the lesion tissue is cauterized. |
