Abstract
The present invention provides a spinal implant for placement between adjacent processes of the human spine. In some embodiments the spinal implant includes a spacer and one or more retention members. In some embodiments, the retention members are fixed relative to the spacer and in other embodiments the retention members are deployable from a first or compact or stowed position to a second or expanded or deployed position. In some embodiments the spacer is expandable from a first size to a second size. In some embodiments the spacer has a tapered body.

1-72. (canceled)
A spinal implant for placement between adjacent processes of a human spine, the spinal implant comprising:
- a spacer including a first end, a second end, a plurality of channels, and a spacer axis extending between the first end and the second end, the plurality of channels extending through the spacer parallel to the spacer axis;
- and
- a plurality of deployable retention members extendable through the plurality of channels.
A spinal implant system for implanting a spinal implant between adjacent spinous processes, the system comprising:
- the spinal implant including:
- a hollow body including a first end, a second end, and a longitudinal axis extending between the first end and the second end, the first end and the second end including a plurality of channels;
- and
- a plurality of deployable retention members extendable through the plurality of channels and extending through the hollow body parallel to the longitudinal axis*;
- and a implantation tube configured to contain at least a portion of the spinal implant for positioning between the adjacent spinous processes.
A spinal implant comprising:
- a hollow body adapted for implantation between adjacent spinous processes, the hollow body including a first end, a second end, and a longitudinal axis extending therebetween;
- and
- a plurality of deployable retention members extendable through the hollow body and when deployed the plurality of deployable retention members extending radially away from the longitudinal axis to grip at least a portion of each of the adjacent spinous processes.
