The grasper may have a first jaw and a second jaw and a main body having a barrel portion. The barrel portion may have a lumen extending therethrough, and a portion of the delivery device may be advanced through the lumen to rotate one or both of the jaws. The delivery devices may include a handle, a shaft, and a distal engagement portion. The delivery devices may further include an actuation rod which may be advanced through a barrel portion of a grasper to actuate the grasper. In some instances, the delivery device may further include a locking sheath, wherein the locking sheath is configured to temporarily couple to a grasper.
