摘要：
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.COPYRIGHT: (C)2015,JPO&INPIT【課題】病変部位以外の他の身体の内部に電流が流れないようにしながらも、身体内の内腔で発生した狭窄または閉塞する病変部位に挿入して拡張させるとともに電気熱を加えて病変組職を焼灼させることができる電気熱治療用ステントを提供する。【解決手段】超弾性形状記憶合金ワイヤ2を編んでなる中空円筒状胴体が長手方向に沿って少なくとも二つ以上の分割胴体10-1、10-2に分割形成され、フレキシブル材の絶縁体20で互いに連結構成され、それぞれの前記分割胴体の後方にワイヤ2が延長されて電源連結線がそれぞれ突設され、それぞれの前記分割胴体の電源連結線に電気発生器を連結し、各分割胴体の間で電流が流れることによって発生する電気熱で病変組職を焼灼する。【選択図】図2
