Abstract
A snare for an endoscope has a snare wire formed from an elastic wire that is connected to the distal end of a control wire axially movably inserted in a flexible sheath. When the control wire is advanced axially, the snare wire projects from the distal end of the flexible sheath and expands in a loop shape by its own elasticity. When the control wire is retracted axially, the snare wire is pulled into the distal end of the flexible sheath and thus contracted. The distal end surface of the flexible sheath is provided with a plurality of claw-shaped projections projecting forward in parallel to each other.
