摘要：
A method of performing a procedure on an intervertebral disc includes inserting a cannulated delivery tube through an opening in an annulus fibrosus of the intervertebral disc, positioning an expandable portion of the tube within the opening in the annulus fibrosus, expanding the expandable portion into contact with the annulus fibrosus about the opening to create a seal between the expandable portion and the annulus fibrosus, performing a procedure through the cannulated delivery tube within the annulus fibrosis, removing the tube, and closing the opening in the annulus fibrosus.
