Abstract:
A distally expanding facet implant with integrated plate and delivery device for distracting a cervical intervertebral facet joint to treat symptoms of degenerative processes of the cervical spine, including widening the intervertebral space and foramina while maintaining or restoring natural lordosis and preventing kyphosis. The distally expanding facet implant with integrated plate and delivery device generally includes opposed plates having distal and proximal ends, a diverting member having a stationary component and a moveable component comprising a diverting nut with a substantially fusiform cross-section between the plates, and a driving member comprising an elongated screw rotationally coupled with the moveable component. Rotation of the screw causes an engagement surface of the diverting nut to slide against a complementary engagement surface of the stationary component. The dimension of the nut present between the distal ends of the plates increases as the surfaces slide against each other causing the distal ends to divert without diverting the proximal ends. Deployed within a facet joint, the implant produces distraction of the facet joint and widening of the intervertebral spacing and foramina while maintaining natural lordosis and preventing kyphosis.

Claim (Index 17):
The implant of  claim 13 , wherein the diverting member comprises a lock adapted to prevent moveable engagement of the second engagement surface with the first engagement surface in a direction toward the first ends of the plates.
