Claims18
A spinal joint distraction system, comprising:
- a spinal facet joint implant;
- a delivery device comprising:
- a tubular shaft;
- and
- a pair of tines extending from a distal portion of the tubular shaft, the tines adapted to penetrate a facet joint;
- and
- a driver assembly comprising:
- an elongated shaft;
- and
- opposing first and second implant engagement portions each extending from a distal portion of the elongated shaft, each implant engagement portion adapted to engage at least a portion of a proximal end face of the spinal facet joint implant,
- wherein at least a portion of the driver assembly is adapted to be received by the tubular shaft of the delivery device.
A spinal joint distraction system, comprising:
- a spinal facet joint implant;
- a delivery device comprising:
