Abstract: Disclosed herein are devices for minimally invasive vertebral augmentation and restoration of spinal lordosis using a steerable cannula assembly. When deployed, the articulating cannula, including an outer cannula and an inner cannula extending into a central lumen of the outer cannula and coupled to each other at their distal ends, can be manipulated to curve/bend the body of the articulating cannula. This manipulation is used to create a void within the interior body and may also be used to control delivery of a treatment element to the interior body.

Abstract: A Posterior Dynamic Stabilization (PDS) device that regulates physiologic spinal elongation and compression. Regulation of elongation and compression are critical requirements of Posterior Dynamic Stabilization devices. Elongation and compression of the device allow the pedicles to travel naturally as the spine flexes and extends. This interpedicular travel preserves a more natural center of rotation unlike some conventional PDS devices that simply allow bending. The device incorporates two components: 1) a spring that allows elongation/compression, and 2) a polymer core component that serves to increase the stiffness of the device in shear, bending, and tension, and also prevents soft tissue ingrowth.

Abstract: This invention relates to an intervertebral motion disc having two opposing endplates, a central articulating core, and a peripheral helical shock absorber.

Abstract: A Posterior Dynamic Stabilization (PDS) device having a telescopic sub-assembly that allows axial movement but restricts bending, shear and in some configurations torsion, and an outer polymeric sleeve component that primarily resists elongation and axial rotation but also encapsulates the telescopic assembly to prevent tissue ingrowth.

Abstract: A Posterior Dynamic Stabilization device that comprises a dual lead titanium spring, a polymer core component disposed within the spring, and a bone anchor attachment feature, wherein the dual rod comprises an intermediate spring portion comprising first and second springs, each spring having a helical intermediate portion, the helical intermediate portions oriented to form a double helix.

Abstract: A flexible rod for use in spinal stabilization having a tube having a helical slit defining a gap and an elastomeric jacket provided in the throughbore of the tube, within the gap, and upon the outer surface of the tube.
