Implant and delivery system for neural stimulator
First Claim
1. Apparatus for use with an optical fiber shape-sensing system, the apparatus comprising:
- an optical fiber, optically couplable to the optical fiber shape-sensing system, and configured to change shape during advancement through a greater palatine canal of a subject;
a delivery tool configured to be removably coupled to the optical fiber and to distally advance the optical fiber through the greater palatine canal; and
a neural stimulator implant, which is (a) shaped and sized to be delivered to a sphenopalatine ganglion (SPG) of the subject by the delivery tool, (b) configured to not be in contact with the optical fiber during delivery of the neural stimulator implant by the delivery tool, and (c) configured to apply electrical stimulation to the SPG.

Abstract
Apparatus is provided for use with an optical fiber shape-sensing system. The apparatus includes an optical fiber, optically couplable to the optical fiber shape-sensing system, and configured to change shape during advancement through a greater palatine canal of a subject. The apparatus additionally includes a delivery tool configured to be removably coupled to the optical fiber and to distally advance the optical fiber through the greater palatine canal. The apparatus further includes a neural stimulator implant, configured to apply electrical stimulation to a sphenopalatine ganglion (SPG) of the subject. The neural stimulator implant is not in contact with the optical fiber, and is shaped and sized to be delivered to the sphenopalatine ganglion (SPG) by the delivery tool. Other applications are also described.

9. A method comprising:
-
using a delivery tool, distally advancing, through a greater palatine canal of a subject, an optical fiber being configured to change shape during advancement through the greater palatine canal; assessing a shape of the palatine canal using an optical fiber shape-sensing system, based on a shape of the optical fiber during advancement; removing the optical fiber from the greater palatine canal; and subsequently to removing the optical fiber, distally advancing through the greater palatine canal a neural stimulator that is configured to apply electrical stimulation to a sphenopalatine ganglion (SPG) of the subject. - View Dependent Claims (10, 11, 12, 13, 14, 15)
