Devices and methods for minimally invasive treatment of degenerated spinal discs

摘要: Spinal stabilization devices and their methods of insertion use to treat degenerated lumbar, thoracic or cervical spinal discs in minimally invasive, outpatient procedures are described. In one embodiment, the device is an expandable cage made a coil perforated cylindrical tube with bulbous bullet-shaped distal end flat rounded proximal end. preferred mechanically expanded larger diameter superelastic nickel-titanium alloy which thermally programmed expand relatively when pre-determined transition temperature below body reached. To disc, guide wire inserted into disc endoscope through posterolateral puncture back advanced up facet spine. Mechanical tools laser energy, under endoscopic visualization, used remove vaporize portion bone, creating opening foraminal space spine for endoscope, enables vertebra nerves be seen. The passageway expanded, mechanical RF energy make tunnel delivery cannula tunnel. An tool insert more preserving mobility spine, while maintaining proper between vertebra. Laser radio frequency (RF) coagulate bleeding, debris shrink annulus close, at least partially, disc.
