Abstract

A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.

15. The device of claim 13, wherein the longitudinal shaft comprises a rod.

16. The device of claim 15, wherein the rod is proximally displaced within the elongated tubular body to disengage the implant and the implant engagement feature.

17. The device of claim 15, wherein the rod is distally displaced within the elongated tubular body to disengage the implant and the implant engagement feature.
