The self-deflecting multilateral junction, according to this aspect, further includes a lateral stinger positioned within the main tubular and releasably coupled to the deflection device, the lateral stinger including a nose end configured to extend into the second flow path, a valve member, and a lateral seal for engaging the lateral seal bore.
