Vertebral joint implants and delivery tools
First Claim
1. A spinal facet implant system, comprising:
- an implant configured for placement in a spinal facet joint space, the implant comprising a leading distal portion and a trailing proximal portion;
a delivery device comprising a tubular body defining a lumen, the delivery device further including a proximal end and a distal end, and an anchoring fork at the distal end; and
a driver assembly comprising;
a hollow implant shaft defining a second lumen, the implant shaft having a proximal end and a distal end, the implant shaft configured to extend through the lumen of the delivery device; and
a handle coupled with the proximal end of the hollow implant shaft; and
wherein the delivery device and the driver assembly are configured such that, when the anchoring fork is positioned in the spinal facet joint space, the implant is advanced into position in the spinal facet joint space.

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.
