METHODS AND SYSTEMS FOR USE IN GUIDING IMPLANTATION OF A NEUROMODULATION LEAD

摘要

Methods and systems for use in guiding implantation of a neuromodulation lead during an implant procedure are disclosed herein. Certain methods and system are for use in guiding implantation of a lead toward an implant position where at least one electrode of the lead is located near a target dorsal root ganglion (DRG). Such methods can involve inserting a distal end of the lead into an epidural space of a spinal column within which is located the target DRG, and using one or more electrodes of the lead to obtain a sensed signal indicative of proximity of at least one electrode of the lead relative to the target DRG. Additionally, the sensed signal is used to guide placement of at least one electrode of the lead toward the implant position near the target DRG.

1. A method for use in guiding implantation of a lead toward an implant position where at least one electrode of the lead is located near a target dorsal root ganglion (DRG), the method comprising:
(a) inserting a distal end of the lead into an epidural space of a spinal column within which is located the target DRG; (b) using at least one electrode of the lead to obtain a sensed signal indicative of proximity of the at least one electrode relative to the target DRG; and (c) using the sensed signal to guide placement of at least one electrode of the lead toward an implant position near the target DRG.
