Abstract: Described herein are devices for reversibly constraining an endoscope. Such devices may comprise: a base positionable proximate a patient; a column extending vertically from the base; an arm extending horizontally from the column; and a clamp coupled to the arm. In some embodiments, the clamp comprises a holder comprising an annular ring defining an endoscope receiving area or a first sidewall and a second sidewall together defining an endoscope receiving area. The holder is transitionable between a first configuration in which the annular ring or the first and second sidewall are configured to set apart from an endoscope in the endoscope receiving area and a second configuration in which the annular ring or the first and second sidewall are configured to clamp the endoscope in the endoscope receiving area.

Abstract: An endoscopic snare tool with a loop wire positioned substantially within a catheter shaft and capable of deploying from and retracting into a distal end thereof at a consistent shape and angle. The shaft may include a guide tip with bisecting bores which guides the loop wire as it deploys or retracts from a lateral position of the shaft so that a consistent shape and angle are maintained. The loop wire may be formed from a composite design or a specially-treated monofilament to further maintain the shape of the loop during reduction or expansion and may further include a torsion spring positioned at a tip of the loop wire to additionally maintain the circular shape of the loop and aid in excision of tissue.
