1. A method comprising:
- using an oral surgical guide generated using CT scan data and comprising (a) an arch portion configured to be placed on a dental arch of a subject, and (b) an extension portion extending from the arch portion, and shaped to define a guide hole to determine (i) a location of a greater palatine foramen of a palate of an oral cavity of the subject, and (ii) a suitable angle for entering a greater palatine canal;
inserting a steerable implantable neural stimulator at the suitable angle into the greater palatine foramen of the subject, through the hole in the surgical guide; and
advancing the stimulator through the greater palatine canal of the subject to a sphenopalatine ganglion (SPG) of the subject.

7. A method comprising:
-
using an oral surgical guide generated using CT scan data to determine (i) a location of a greater palatine foramen of a palate of an oral cavity of a subject, and (ii) a suitable angle for entering a greater palatine canal; inserting a steerable implantable neural stimulator at the suitable angle into the greater palatine foramen of the subject, through a hole in the surgical guide; and advancing the stimulator through the greater palatine canal of the subject to a sphenopalatine ganglion (SPG) of the subject, wherein inserting the stimulator comprises inserting the stimulator using a tool, and wherein the method further comprises, following the advancing of the stimulator, allowing the tool to be withdrawn from the greater palatine canal without dislodging the stimulator, by disengaging a locking element of the stimulator from the tool, and wherein the locking element is shaped as a ball, and wherein disengaging the locking element comprises disengaging the ball-shaped locking element from the tool.
