Abstract
A flexible sheath is removably inserted into an instrument-inserting channel of an endoscope. A treating member for applying a treatment to mucous membrane in a body cavity is projected from and withdrawn into the distal end of the sheath by an operation conducted at the proximal end of the sheath. An exposed electrode is provided at the distal end surface of the sheath. An electrically conductive member extending through the sheath is electrically connected at a distal end thereof to the electrode and at a proximal end thereof to a high-frequency power supply at the proximal end of the sheath.
