Abstract: A retrieval device attachable to a scope includes a handle which has an attachment portion configured to couple the handle to the scope; a shaft coupled to the handle having a wire immovably coupled to the handle; and a sheath movable relative to the handle over the wire between a distal position and a proximal position via an actuator of the handle. The actuator actuates a slider assembly of the handle. The slider assembly is coupled to the sheath and movable relative to the attachment portion to move the sheath and an expandable end effector coupled to the distal end of the wire. The end effector is movable between a collapsed configuration when the sheath is moved distally to the distal position to cover the end effector and an expanded configuration when the sheath is moved proximally to the proximal position, uncovering the end effector.

Abstract: An endoscopic deployment device includes a body mountable on an endoscopic device, a communication interface, and a motor. The body has a movable carrier couplable to an elongated end effector device. The effector device has an end effector shaft covered by an outer sheath and an end effector extending from a distal end of the shaft. The sheath is sized and shaped for insertion through a working channel of an endoscopic shaft of the endoscopic device. The body has a carrier channel sized for the carrier to slide therein. The end effecter is actuatable between open and closed positions by sliding the carrier in the carrier channel which in turn slides the sheath over the end effector shaft to uncover/cover the end effector. Rotation of a drive shaft of the motor is sliding the carrier in the carrier channel and actuating the end effector in response to a signal.
