Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 60 words
1 . An intervertebral disc assembly comprising a nucleus pulposus; an annulus fibrosus substantially surrounding a lateral edge of said nucleus pulposus, wherein said annulus fibrosus has a defect therein; and a cured bio-compatible, cross linked polymeric visco-elastic sealant in said defect in a form sufficient to at least impede exudation and extrusion of nucleus pulposus material through said defect.
Claim 2
Dependent Claim 60 words
1 . An intervertebral disc assembly comprising a nucleus pulposus; an annulus fibrosus substantially surrounding a lateral edge of said nucleus pulposus, wherein said annulus fibrosus has a defect therein; and a cured bio-compatible, cross linked polymeric visco-elastic sealant in said defect in a form sufficient to at least impede exudation and extrusion of nucleus pulposus material through said defect.
Claim 3
Dependent Claim 30 words
2 . An intervertebral disc assembly as claimed in claim 20 wherein said sealant has been disposed in said defect in an uncured condition, and has been cured in situ.
Claim 4
Dependent Claim 24 words
3 . An intervertebral disc assembly as claimed in claim 20 wherein said sealant has been disposed in said defect in a cured condition.
