Minimally invasive spinal fusion implant systems and methods

A system for stabilizing a joint between a superior vertebra and an inferior vertebra, the system comprising:

• an implant comprising:
• a body;
• a wing mechanism configured to engage a superior spinous process and an inferior spinous process;
• and
• a first actuation mechanism configured to engage the wing mechanism;
• wherein:
• actuation of the first actuation mechanism expands at least a portion of the body to distract an interspinous space between the superior vertebra and the inferior vertebra;
• and
• further actuation of the first actuation mechanism deploys the wing mechanism to engage the superior spinous process and the inferior spinous process.

A system for stabilizing a joint between a superior vertebra and an inferior vertebra, the system comprising:

• an implant comprising:
• a body configured to be implanted between a superior spinous process of the superior vertebra and an inferior spinous process of the inferior vertebra;
• a first facet arm;
• a second facet arm;
• and
• a wing mechanism configured to engage the superior spinous process and the inferior spinous process;
• and
• a guided access device configured to be docked with an interspinous space between the superior vertebra and the inferior vertebra;
• wherein:
• the guided access device comprises a cannula configured to receive the implant and direct the implant to the interspinous space;
• the implant is configured to pass through the cannula to engage the superior vertebra and the inferior vertebra;
• the first facet arm comprises a first aperture configured to be aligned with a first facet joint;
• the second facet arm comprises a second aperture configured to be aligned with a second facet joint;
• the guided access device further comprises a first trajectory guide comprising a first longitudinal axis that is alignable with the first aperture;
• and
• the guided access device further comprises a second trajectory guide comprising a second longitudinal axis that is alignable with the second aperture.
