Claim:
1. An intranasal device for delivering a medicament to a patient in need thereof comprising: an injector comprising a first, proximal, end including a hub with a syringe-attachment Luer structure, said first end configured to remain outside a nasal passage of the patient; a second, distal, end configured for entry into the nasal passage of the patient; and a tubular injector body between the first end and second end; and an introducer configured for engagement with a nostril of the patient, wherein the introducer comprises an introducer passageway configured for slidably receiving the injector, wherein the introducer passageway slidably receives a syringe barrel when a hub-attached syringe is advanced distally within the introducer; wherein the injector is moveable, relative to the introducer, between a storage position and an engaging position; wherein the hub comprises a radially-extending stop bar and wherein an inward-facing surface of the introducer passageway comprises a pair of substantially parallel longitudinal ledges configured to abut against and be tracked along by the stop bar on first and second opposing sides of the stop bar, wherein said ledges provide for a first longitudinal linear path and a second longitudinal linear path, each parallel to the other and to a central longitudinal axis, separated radially from each other by a predetermined number of degrees of rotation corresponding to a desired medicament delivery angle; and wherein the length of the ledges corresponds to at least a portion of longitudinal distance between the storage position and the engaging position of the injector relative to the introducer.
