Abstract
Apparatus for treating a subject is provided, the apparatus comprising (a) a stimulation device (352), adapted to be implanted in a vicinity of a site selected from the list consisting of: a sphenopalatine ganglion (SPG) (52) of the subject and a neural tract originating in or leading to the SPG; and (b) a connecting element (356), coupled to the stimulation device (352), and adapted to be passed through at least a portion of a greater palatine canal (282) of the subject. Also provided is a method for implanting a treatment stimulation device (352) in a vicinity of a site of a subject, the method comprising passing the device (352) through a greater palatine foramen (22) of the subject, and bringing the device (352) into contact with the vicinity of the site, the site selected from the list consisting of: a sphenopalatine ganglion (SPG) (52) of the subject and a neural tract originating in or leading to the SPG.

113. An apparatus for insertion into a greater palatine canal of a subject, comprising a stylet, which comprises:
-
a proximal rod shaft, having a first diameter; and a distal rod shaft, having a second diameter less than the first diameter, such that a region between the proximal rod shaft and the distal rod shaft is shaped so as to define a shoulder which is adapted to prevent insertion of the distal rod shaft into a sphenopalatine fossa of the subject beyond a depth of the greater palatine canal, wherein the proximal rod shaft has a length of between about 20 mm and about 150 mm, wherein the first diameter is between about 1.5 mm and about 6 mm, wherein the distal rod shaft has a length of between about 3 mm and about 20 mm, and wherein the second diameter is between about 1 mm and about 1.5 mm. - View Dependent Claims (114, 115)

116. A method comprising:
-
inserting a stylet into a greater palatine canal of a subject, the stylet including a proximal rod shaft, having a first diameter, and a distal rod shaft, having a second diameter less than the first diameter, such that a region between the proximal rod shaft and the distal rod shaft is shaped so as to define a shoulder; and advancing the stylet through the greater palatine canal until the shoulder reaches an entrance of a greater palatine foramen, thereby preventing insertion of the distal rod shaft into a sphenopalatine fossa of the subject beyond a depth of the greater palatine canal. - View Dependent Claims (117, 118)
