Systems and methods for preventing, mitigating, or reducing the occurrence of impedance-related stoppages during radiofrequency procedures, such as intraosseous nerve or basivertebral nerve ablation procedures for treatment or prevention of back pain or other tissue ablation, stimulation, or other modulation or modification procedures are described.

Impedance stoppage mitigation during radiofrequency tissue ablation procedures

A steerable, or curveable, introducer drill to access a target treatment region within bone along a curved trajectory is disclosed. The drill may include a drive shaft including a proximal rotational member, a distal drill tip, and an elongate shaft portion extending from the proximal rotational member to the distal drill tip. The distal drill tip may be sharp and include cutting flutes. The drill may also include an outer tube surrounding the drive shaft. A distal end portion of the outer tube may include a segmented tube section configured to facilitate controlled bending of the segmented tube section of the outer tube. The drill may also include an actuator operably coupled to the drive shaft and adapted to apply tension to the drive shaft which, in turn, causes the segmented tube section of the outer tube to bend.

Introducer drill

Described herein are various implementations of systems and methods for accessing and modulating tissue (for example, systems and methods for accessing and ablating nerves or other tissue within or surrounding a vertebral body to treat chronic lower back pain). Assessment of vertebral endplate degeneration or defects (e.g., pre-Modic changes) to facilitate identification of treatment sites and protocols are also provided in several embodiments. Several embodiments comprise the use of biomarkers to confirm or otherwise assess ablation, pain relief, efficacy of treatment, etc. Some embodiments include robotic elements for, as an example, facilitating robotically controlled access, navigation, imaging, and/or treatment.
