The invention provides a selective system of placing a guide stock into a wellbore by braided line, coil tubing or drill pipe. The device facilitates selective intervention by providing a selective orientation key an angular relationship to the lateral through a system of selective keys and dogs allowing the diverter of the guide stock to be aligned at any desired angle with the orientation sub. The orientation sub includes a key for picking up on a helical slot in the packer to rotate the assembly and a set of selectively profiled dogs to engage a selected packer and halt downhole movement of the device.
