Abstract

The invention relates to a systems, devices and methods of delivering and deploying a stent into a curvilinear cavity within a vertebral body or other bony or body structure. In some instances, a system can include an elongate shaft for delivering a self-expanding, cement-directing stent. The elongate shaft can include at least one of an inner shaft, an outer shaft, a tubular sheath, a flexible guidewire, and an internal polymer extrusion. A rotational handle can be used to control movement of the elongate shaft. The rotational handle can incorporate one or more pins in slots associated with each of the components (e.g., inner shaft, outer shaft, and tubular sheath), such that upon rotation of the handle, the pins are forced to move in the direction of their respective slots.
