US Patent 8623024 Implantation tools for interspinous process spacing device

Various embodiments described herein provide devices and associated methods for treating spinal disease by implanting one or more interspinous process spacing devices. In one embodiment, an interspinous process spacing device includes a first attachment side and a second attachment side, whereby each attachment side includes one or more slots formed in the outer surface and oriented proximate one end for receiving fasteners extending inwardly from a second interspinous process spacing device. The device further includes a spacer tray positioned between the first attachment side and the second attachment side, the spacer tray extending from the first attachment side and slideably insertable through a tray slot formed in the second attachment side, wherein the spacer tray is adapted to retain adjacent spinous processes in a spaced apart orientation. The device further includes securing means for securing the second attachment side relative to the first attachment side, wherein, upon securing the second attachment side relative to the first attachment side, the interspinous process spacing device is engaged with the adjacent spinous processes.
