Abstract
Systems and methods for augmenting a vertebral body may include an optional access cannula, introducer device, and a stylet having a stylet shaft. The access cannula includes a hub portion and a cannula shaft extending from the cannula hub. The cannula shaft includes a distal end positionable within the vertebral body that defines a lumen along a longitudinal axis. The introducer device may be a telescoping or pivoting introducer device that is removably coupled to the hub portion of the access cannula. The introducer device controls the movement of the flexible distal portion of the stylet shaft and the flexible sheath from within the introducer device through the access cannula to within a target site in the vertebral body, wherein the flexible distal portion is moved from the constrained to the unconstrained state to displace cancellous bone within the target site.
