Abstract: A cannula tool in combination with other tools is used to provide multiple instruments necessary for surgical procedures. The cannula tool is used in combination with a piercing tool to form a dilator instrument to access a treatment site and in combination with a plunger tool to deliver biological or grafting material to a treatment site. Each of the plunger and piercing tools includes a guide lumen to track the tools over a K-wire or other guide device for placement at the treatment site. The application discloses asymmetrical piercing and plunger tools for placement proximate to a facet joint for treatment.

Abstract: The present application discloses an implantable device for spinal treatment or stabilization. The device includes a spinal rod support and gripping jaws. The gripping jaws operate between an opened position and a closed position to grip and release a first spinal rod implanted into a patient. The spinal rod support includes a perimeter structure having an interior cavity and passage to connect a second spinal rod to the device to operably connect the first and second spinal rods through the implantable device to form a spinal stabilization structure.
