A method for guiding a therapy delivery device to a sympathetic nerve chain target of a subject includes: (a) selecting a sympathetic nerve chain target; (b) using ultrasound imaging to obtain an ultrasound image of anatomical structures relevant to the sympathetic nerve chain target; (c) determining an implantation pathway based on the ultrasound image, the implantation pathway defining a trajectory that avoids the relevant anatomical structures and extends between an insertion point on the skin of the subject and a bony spinous target; (d) inserting an introducer into the insertion point, the introducer including a bevel located at a distal end thereof; (e) navigating the introducer through the implantation pathway until the distal tip is positioned adjacent or proximate to the bony spinous target; and (f) advancing the therapy delivery device through the introducer to the sympathetic nerve chain target. Steps (d)-(f) are performed using real-time ultrasound imaging.
