Abstract:
1. A method of delivering a nucleus pulposus replacement material comprising: inserting a cannulated delivery tube through an opening in an annulus fibrosus of an intervertebral disc, the cannulated delivery tube including an inflatable balloon; positioning the inflatable balloon within the opening in the annulus fibrosus; expanding the inflatable balloon into contact with the annulus fibrosus about the opening to create a seal between the balloon and the annulus fibrosus; delivering through the tube and the sealed opening in the annulus fibrosus an amount of a nucleus pulposus replacement material directly into the annulus fibrosus and not into an implant placed in the annulus fibrosus, the nucleus pulposus replacement material contacting an inner wall of the annulus fibrosis; removing the tube; and closing the opening in the annulus fibrosus.
