Abstract
Abstract An implantable spinal stabilizing device, developed initially for correcting and maintaining the correction of scoliotic curves, but also useful for fixing spinal fractures and dislocations, involves a pair of spaced parallel rigid bars, each bar having a succession of apertures. The bars are located on opposite sides of the spinous processes, between the spinous and respective transverse processes, and held in this location by tape laced through the bar apertures and around the spinous laminae or transverse processes. The tape is tensioned and secured by plugs in the relevant apertures, and the overall assembly serves to stabilize the spine in a required configuration.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
96 words
An implantable spinal stabilizing device comprising two rigid bars to be located one at each side of the spinous processes between the spinous and respective transverse processes and including a length of tape, each of said bars having a plurality of apertures therein and disposed in a sequence along the bar for receipt of said tape in laced engagement tHerewith while embracing adjacent transverse processes or laminae, means for securing said tape to said bars, and rigid spacer means for holding said bars in substantially parallel spaced apart relationship at opposite sides of the spinous processes.
Claim 2
Dependent Claim
96 words
An implantable spinal stabilizing device comprising two rigid bars to be located one at each side of the spinous processes between the spinous and respective transverse processes and including a length of tape, each of said bars having a plurality of apertures therein and disposed in a sequence along the bar for receipt of said tape in laced engagement tHerewith while embracing adjacent transverse processes or laminae, means for securing said tape to said bars, and rigid spacer means for holding said bars in substantially parallel spaced apart relationship at opposite sides of the spinous processes.
Claim 3
Dependent Claim
38 words
A device according to claim 1 wherein said apertures are tapered in a common direction through said bars, and said securing means comprise a plurality of tapered plugs for individual engagement in said apertures having tape laced therethrough.
Claim 4
Dependent Claim
13 words
A device according to claim 2 wherein said plugs have serrated side surfaces.
Claim 5
Dependent Claim
28 words
A device according to claim 2 wherein said securing means further comprises two cover plates for respective connection along said bars over the larger ends of said apertures.
Claim 6
Dependent Claim
30 words
A device according to claim 1 wherein slots are provided between one side of each of said bars and the respective apertures therein to facilitate lacing of tape without threading.
Claim 7
Dependent Claim
41 words
A device according to claim 1 wherein said spacer means comprise two rigid bars of shorter length than the first-mentioned bars, said first bars and spacer bars being adapted for interconnection at their ends to form a rigid generally rectangular assembly.
Claim 8
Dependent Claim
43 words
A device according to claim 6 wherein each of said first bars extend beyond its connection points with said spacer bars, has a plurality of said apertures extending between said points, and has at least one aperture therein beyond each of said points.
Claim 9
Dependent Claim
92 words
A device according to claim 1 wherein: said apertures provided with slots between one side of each of said bars and the respective apertures, and said apertures are tapered in a common direction through said bars; said securing means comprise a plurality of tapered serrated plugs for individual engagement in said apertures having tape laced therethrough; and said spacer means comprise two rigid bars of shorter length than the first mentioned bars, said first bars and spacer bars being adapted for interconnection at their ends to form a rigid generally rectangular assembly.
