Device and method for manipulating intervertebral tissue
First Claim
1. An intervertebral tissue removal system comprising:
- an intervertebral tissue removal system conduit;
a segmented expansion media configured to pass through the intervertebral tissue removal system 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 opening size, to an expanded condition whereat the at least one opening has a second opening size larger than the first opening size, wherein the second opening size is sized such that the segmented expansion media cannot pass through the at least one opening, 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.

Abstract
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.

12. A method of removing intervertebral tissue, comprising:
-
inserting at least one abrading member for abrading tissue into an area to be cleared; inserting a segmented expansion media through an intervertebral tissue removal system conduit into an expandable node of the at least one abrading member, the expandable node including a plurality of abrading strands; forcing the segmented expansion media against the plurality of abrading strands, thereby expanding the expandable node from a first condition whereat the plurality of abrading strands define at least one opening having a first opening size, to an expanded condition whereat the at least one opening has a second opening size, wherein the second opening size is sized such that the segmented expansion media cannot pass through the at least one opening; abrading tissue in the area to be cleared with the expanded expandable node; and removing the abraded tissue from the area to be cleared. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
