Abstract

A medical device includes an endoscope and an endoscopic treatment instrument. An insertion portion of the endoscope includes a treatment instrument lumen and a curved part. The endoscopic treatment instrument includes a tube having a knife wire lumen, a knife wire housed in the knife wire lumen, and a support member. The knife wire includes a first wire part including an exposed part, and a second wire part. In a specific state in which the endoscopic treatment instrument is inserted into the treatment instrument lumen and a portion from a position of a distal end of the exposed part of the knife wire exposed from the tube to a proximal end side by a predetermined distance is projected from an opening of the insertion portion, a distal end of the second wire part is located on a more distal end side than a proximal end of the curved part.
