1. A method for treating a basivertebral nerve in a vertebral body of a patient, the method comprising:
inserting an introducer having a handle coupled to a shaft defining a central channel and an opening at a distal tip through a pedicle of the vertebral body until the opening reaches the cancellous bone of the vertebral body;
delivering a cannula having a proximal end, a rotatable member, and a distal end through the central channel of the introducer, wherein the cannula distal end is deflectable relative to a central axis of the introducer;
advancing the cannula and a first stylet coupled with the cannula distal end further into the cancellous bone while rotating the rotatable member;
extending the cannula and the first stylet past the opening at the distal tip of the introducer to generate a curved path in the cancellous bone; and
via a treatment device coupled with the cannula distal end, delivering treatment to a treatment location proximate the basivertebral nerve.
