摘要： A treatment apparatus to treat a tissue in a body cavity is disclosed. The apparatus comprises a base disposed in the vicinity of a tip-end portion of an endoscope, and an in-tissue inserting portion including a base end supported by the base and a tip end insertable in the tissue in the body cavity in a direction substantially parallel to the surface of the tissue, and extending to the tip end from the base end in a tapered shape. The in-tissue inserting portion has an inner side disposed in the vicinity of the surface of the tissue when inserted into the tissue. The apparatus further comprises a high-frequency electrode, for treating the tissue, supported by the base and disposed in the vicinity of the inner side of the in-tissue inserting portion, and a cable which supplies power to the high-frequency electrode from a high-frequency power source outside the body.
