Abstract
The invention relates to the repair of spinal annular defects. An appartatus comprises a scaffold comprised of a biodurable, resiliently compressible, elastomeric reticulated composition to obliterate spinal/vertabral connective tissue defects, to obliterate spinal-annular nuclear tissue defects, and for spinal annulo-nucleoplasty regeneration. The apparatus comprises an at least partially cylindrical member.
Claims24
A method of treating spinal annular defects which comprise the steps of:
- (a) inserting an at least partially cylindrical apparatus comprising a scaffold comprised of a biodurable, resiliently compressible, elastomeric reticulated matrix into the lumen of a delivery means;
- (b) advancing the distal tip of the delivery means into an opening in an annulus;
- (c) advancing the apparatus through the lumen into the opening;
- and (d) withdrawing the delivery means, whereby the apparatus expands into the opening.
