Abstract
A technique facilitates deflecting a tubing string into a desired branch of a surrounding tubular structure. A deflector assembly is provided with a deflector tube, an orienting member, and a latching feature, such as latch dogs which are circumferentially disposed on the deflector tube in an asymmetrical pattern. The deflector assembly may be moved within the outer tubular structure, e.g. wellbore tubing, to a desired junction. The deflector tube and the latching feature are then oriented in an alignment sleeve of the surrounding tubular structure by moving the orienting member along a profile within the outer tubular structure. The latching feature is able to securely latch at the selected junction. The latching feature may use a pattern of latch dogs which matches a corresponding asymmetrical pattern of latch openings in the alignment sleeve.
