    Abstract: An endoscopic tissue resection device configured to be attached at a distal tip of an endoscope is disclosed. The device comprises a cap, a snare sheath, a snare, and a spring wire. The snare comprises a collapsible snare wire configured to be retracted from the cavity of the cap into the snare sheath, the collapsible snare wire reversibly collapsing upon retraction, and to be advanced from the snare sheath into the cavity of the cap, the collapsible snare wire reversibly expanding upon advancement. The spring wire is reversibly deflectable from a resting state to a deflected state. In the resting state the spring wire orients and stabilizes an apex of the collapsible snare wire within the cap such that two opposing wire portions of the collapsible snare wire are positioned in apposition to a distal opening of the cap.
