Abstract

Systems and methods for augmenting a vertebral body. The system includes an access cannula, an introducer device, a sheath device, and a treatment device. The introducer device may be moved from unconstrained state to a constrained state in which a pulling element is tensioned. The access cannula may initially prevent the shaft sheath from assuming a curve, after which the introducer device and the sheath device may be advanced relative to the access cannula to assume the curve within the vertebral body. An actuator of the introducer device may include a resilient arm configured to resiliently deflect such that a lock head releasably engages a feature of a handle of the introducer device. A spacer lock facilitates proximal movement of the sheath relative to the access cannula so as to expose the treatment device within the vertebral body at a location offset from a longitudinal axis of the access cannula.
