Interspinous process spacer
First Claim
1. A device for placement between a pair of spinous processes, the device comprising:
- (a) opposed abutment surfaces sized and shaped for engaging adjacent spinal processes;
(b) at least one side-to-side through channel disposed between the opposed abutment surfaces; and
(c) at least one band receivable in the through channel.

Abstract
An interbody or intervertebral spacer device for placement in an interspinous space between a pair of adjacent interspinous processes includes arcuate opposed abutment surfaces sized and shaped for engaging adjacent spinal processes. A curved through channel is disposed between the opposed abutment surfaces. A pair of bands is receivable in the curved through channel. A method of implanting such an interspinous spacer includes the steps of making an incision lateral to the spine; laterally inserting the spacer between a pair of interspinous processes without detachment of the supraspinous ligament; and laterally securing the spacer to the pair of interspinous processes with a pair of bands.

9. In a device for placement between adjacent spinous processes having opposed abutment surfaces for engaging adjacent spinal processes and at least two bands for attaching the interbody device to the spinous processes, the improvement wherein:
the device defines a through channel located between the abutment surfaces and running substantially transverse to the abutment surfaces, the through channel receiving the at least two bands therethrough. - View Dependent Claims (10, 11, 12)

13. In a device for placement between adjacent spinous processes having opposed abutment surfaces for engaging adjacent spinal processes and at least two bands for attaching the interbody device to the spinous processes, the improvement wherein:
the device is asymmetrical, with one of the abutment surfaces defining a curvate furrow and the opposed abutment surfaces being curvate and smooth. - View Dependent Claims (14)

15. In a method of implanting an interspinous spacer, the improvement including the steps of:
-
a) making an incision; b) unilaterally inserting the spacer between a pair of interspinous processes without detachment of the supraspinous ligament; and c) securing the spacer to the pair of interspinous processes with a pair of bands.

16. In a method of implanting an interspinous spacer, the improvement including the steps of:
-
a) making an incision in skin located over the spine; b) inserting the spacer between a pair of interspinous processes from one side of the spine without detachment of the supraspinous ligament; and c) securing the spacer to the pair of interspinous processes with a pair of bands.
