Methods, systems and devices for neuromodulating spinal anatomy

摘要

Devices, systems and methods for treating pain or other conditions while minimizing possible complications and side effects. Treatment typically includes electrical stimulation and/or delivery of pharmacological or other agents with the use of a lead or catheter. The devices, systems and methods provide improved anchoring which reduces migration of the lead yet allows for easy repositioning or removal of the lead if desired. The devices, systems and methods also provide for simultaneous treatment of multiple targeted anatomies. This shortens procedure time and allows for less access points, such as needle sticks to the epidural space, which in turn reduces complications, such as cerebral spinal fluid leaks, patient soreness and recovery time. Other possible complications related to the placement of multiple devices are also reduced.

主权项

1. A method comprising:
advancing a lead into a body of a patient through an epidural space of the body, the lead comprising a shaft having a distal tip and at least one electrode disposed a distance along the shaft proximal to the distal tip; positioning the distal tip near a first dorsal root ganglion by initially passing out from the epidural space through an intervertebral foramen associated with a second dorsal root ganglion and guiding the distal tip past the second dorsal root ganglion and then inward toward the first dorsal root ganglion, wherein the first and second dorsal root ganglia are on different spinal levels; positioning the at least one electrode near the second dorsal root ganglion; and stimulating the second dorsal root ganglion with the at least one electrode.
