Back pain treatment methods

摘要

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).

1. A method of energy delivery to a vertebral body, comprising:
inserting an introducer assembly through soft tissue and positioning a distal end of the introducer assembly at a surface of a vertebral body, wherein the introducer assembly comprises an elongate shaft and a sharpened, straight stylet received within the elongate shaft; confirming proper positioning of the introducer assembly; withdrawing the sharpened, straight stylet from the elongate shaft; inserting a curved cannula assembly through the elongate shaft and advancing a distal tip of the curved cannula assembly beyond the distal end of the introducer assembly and into an inner cancellous bone region of the vertebral body, wherein the curved cannula assembly comprises a curved cannula and a curved stylet, wherein a distal portion of the curved cannula and a distal portion of the curved stylet have corresponding curves that are configured to be aligned, wherein the curved cannula assembly forms a curved path within the inner cancellous bone region toward a target treatment site; confirming proper positioning of the curved cannula assembly with respect to the target treatment site; withdrawing the curved stylet from the curved cannula; advancing a distal end of a straight channeling stylet through the curved cannula and beyond an opening at a distal end of the curved cannula and through bone tissue to the target treatment site, thereby creating a linear path within the bone tissue; removing the straight channeling stylet from the curved cannula while maintaining the position of the curved cannula and the introducer assembly; inserting an energy delivery device within the curved cannula and advancing a distal end of the energy delivery device beyond the opening at the distal end of the curved cannula along the linear path within the bone tissue to the target treatment site; confirming proper positioning of the distal end of the energy delivery device at the target treatment site; and activating the energy delivery device to cause energy to be delivered to the target treatment site sufficient to denervate at least a portion of a basivertebral nerve within the vertebral body.
