摘要：
A system and method for manipulating intervertebral tissue in one embodiment includes a conduit, a segmented expansion media configured to pass through the conduit, and an expandable node comprising a plurality of abrading strands and operably connected to the intervertebral tissue removal system conduit so as to receive the segmented expansion media therein, the expandable node expandable from a first condition whereat the plurality of abrading strands define at least one opening having a first maximum diameter, to an expanded condition whereat the at least one opening has a second maximum diameter larger than the first maximum diameter, wherein the second maximum diameter is less than a minimum diameter of the segmented expansion media, such that insertion of the segmented expansion media through the intervertebral tissue removal system conduit and into the expandable node causes the expandable node to expand from the first condition to the expanded condition.
