INTERSPINOUS PROCESS CUSHIONED SPACER
First Claim
1. An interspinous process spacer implant device adapted to be inserted between two adjacent spinous processes, the implant device comprising:
- an implant body including;
a central portion defining a left side, a right side, an anterior face, and a posterior face;
opposing first and second superior legs extending upwardly from the central portion in a spaced fashion to define a superior zone for receiving a spinous process;
opposing first and second inferior legs extending downwardly from the central portion in a spaced fashion to define an inferior zone for receiving a spinous process;
wherein the central portion is adapted to support spinous processes disposed within the superior and inferior zones, respectively, and forms a continuous, lateral passage extending through the central portion such that the lateral passage is open at both the left and right sides.

Abstract
An implantable dorsal spinous process spacer device including an implant body having a central portion, opposed superior legs, and opposed inferior legs. The central portion defines a lateral passage extending between, and exteriorly open to, left and right sides thereof. Optional cushions are affixed to opposite faces of the central portion, within receiving zones defined thereby. The implant body is attached to adjacent spinous processes. The implanted device spreads apart the posterior vertebral structures relieving a variety of disabling spine problems that have resulted from degenerative disc collapse. A narrow non-absorbable woven band, strap or plurality of suture filaments is passed around the two spinous processes, crossing through a lateral passage provided in the implant, stabilizing the spinal segment.

15. A kit for repairing a damaged vertebral column including adjacent vertebral segments each having a posterior spinous process, the kit comprising:
-
first and second interspinous process spacer implant devices, each comprising; an implant body including; a central portion defining a left side, a right side, an anterior face, and a posterior face; opposing first and second superior legs extending upwardly from the central portion in a spaced fashion to define a superior zone for receiving a spinous process; opposing first and second inferior legs extending downwardly from the central portion in a spaced fashion to define an inferior zone for receiving a spinous process; wherein the central portion is adapted to support spinous processes disposed within the superior and inferior zones, respectively, and forms a continuous, lateral passage extending through the central portion such that the lateral passage is open at both the left and right sides; wherein a lateral spacing between the superior legs of the first implant device is greater than a lateral spacing between the superior legs of the second implant device. - View Dependent Claims (16, 17, 18)

19. A method of repairing a damaged vertebral column including adjacent superior and inferior vertebral segments each having a posterior spinous process, the method comprising:
-
providing an interspinous process spacer implant device comprising an implant body including a central portion, opposing superior legs, and opposing inferior legs, wherein the superior legs extend upwardly from the central portion in a spaced fashion to define a superior zone, and the inferior legs extend downwardly from the central portion in spaced fashion to define an inferior zone; positioning the spinous process of the superior vertebral segment within the superior zone; positioning the spinous process of the inferior vertebral segment within the inferior zone; and passing a band through the lateral passage and about the superior legs to secure the implant device to the superior vertebral segment; wherein upon final implant the implant device establishes and maintains a spacing between the vertebral segments. - View Dependent Claims (20)
