The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A spinal implant for placement between adjacent processes of the human spine comprising:
a spacer having a first end, a second end, and a spacer axis; extending therebetween,
the spacer having an outer surface spaced from the spacer axis; and at least one deployable retention member moveable from a first position in which the retention member is positioned generally at or inwardly of the outer surface to a second position in which the retention member projects outwardly beyond the outer surface.
2. The spinal implant of claim 1 wherein the retention member comprises a loop.
3. The spinal implant of claim 1 wherein the retention member is contained within the spacer in the first position.
4. The spinal implant of claim 1 wherein the spacer includes an interior cavity receiving
the retention member and an actuator mounted to the spacer, the actuator being responsive to rotation to translate relative to the spacer and move the retention member from the first position to the second position.
5. The spinal implant of claim 1 wherein the retention member is biased into a curved shape and wherein the retention member is elastically straightened in the first position and recovers to its curved shape in the second position.
6. The spinal implant of claim 1 wherein the spacer includes a passageway at least partway through the spacer and at least a portion of the retention member moves within the passageway from the first position to the second position.
7. The spinal implant of claim 6 further comprising a fixed extension projecting outwardly beyond the outer surface adjacent the first end, an interior cavity that houses the retention member, and an actuator screw threadably engaged with the spacer, the actuator screw being responsive to rotation to translate relative to the spacer and move the retention member from the first position to the second position, the retention member projecting outwardly beyond the outer surface adjacent the second end.
8. The spinal implant of claim 1 wherein the spacer includes a curved passageway and at least a portion of the retention member moves through the passageway from the first position to the second position causing the portion to curve as it moves to the second position.
9. The spinal implant of claim 1 further comprising at least one end piece spaced further from the spacer in the first position and spaced nearer to the spacer in the second position, the end piece including a passageway receiving at least a portion of the retention member for translation therethrough.
10. The spinal implant of claim 9 further comprising a threaded shaft connecting the spacer to the end piece, the shaft being responsive to rotation to move the spacer and shaft nearer to one another and thereby force the retention member to project out of the end piece and away from the spacer axis.
11. The spinal implant of claim 1 wherein the spacer comprises a passageway extending through it, the spinal implant further comprising a core receivable in the passageway, the retention member being mounted to the core.
12. The spinal implant of claim 11 wherein the retention member is mounted to the core in generally outwardly oriented relationship transverse to the spacer axis, the retention member being elastically moveable to a position generally parallel to the spacer axis for insertion with the core through the passageway.
13. The spinal implant of claim 12 further comprising a tube removably received around the core and retention member temporarily maintaining the retention member generally parallel to the spacer axis.
14. The spinal implant of claim 11 wherein the retention member comprises a plurality of strands moveable from an orientation along the sides of the spacer to a pattern of loops extending outwardly transverse to the spacer axis.
15. The spinal implant of claim 14 wherein the strands comprise first and second strand ends and the first strand ends are mounted for translation nearer to the second strand ends, the strands being responsive to translation of the first strand ends nearer to the second strand ends to project outwardly transverse to the spacer axis and form a pattern of loops.
16. The spinal implant of claim 11 wherein the spacer is deformable from a first dimension transverse to the spacer axis to a second, smaller, dimension transverse to the spacer axis to facilitate insertion between adjacent processes prior to inserting the core.
17. The spinal implant of claim 16 wherein the spacer is responsive to stretching transverse to the spacer axis to deform from the first dimension to the second dimension.
18. The spinal implant of claim 1 wherein the spacer comprises a passageway extending through it generally parallel to the spacer axis and the retention member comprises a strip of material having a nominally curved shape, the retention member being withdrawn into the passageway at at least a first end of the passageway in the first position and the retention member extending from the first end of the passageway in the second position.

20. A spinal implant for placement between adjacent processes of the human spine comprising:
a spacer having a first end, a second end, a spacer axis extending therebetween, a passageway through the spacer having a first passageway end and a second passageway end, and an outer surface spaced from the spacer axis; and
at least one deployable retention member comprising an elongated member preformed into a nominal shape able to extend outwardly from the passageway transverse to the spacer axis beyond the outer surface, the retention member being receivable through the passageway from the first passageway end to the second passageway end, the retention member being responsive to exiting the second passageway end to recover its nominal shape and extend outwardly beyond the outer surface.
21. A spinal implant for placement between adjacent processes of the human spine comprising:
a spacer having a first end, a second end, a spacer axis extending therebetween, and
an outer surface spaced from the spacer axis; and at least one deployable retention member mounted adjacent the first end and being expandable from a first position in which the retention member is positioned generally at or inwardly of the outer surface to a second position in which the retention member projects radially outwardly beyond the outer surface.
