1. An apparatus for disrupting tissue in an intervertebral disc space, comprising:
- a delivery cannula;
a barrier member having a first configuration for insertion into the disc space within the delivery cannula; and
a tissue disruption tool positioned within the delivery cannula, externally of the barrier member, for insertion into the disc space, whereinthe barrier member has a second configuration when deployed outside of the delivery cannula and within the disc space in which the barrier member at least partially defines a perimeter of a working region within the disc space, andthe tissue disruption tool is configured for advancement outside of the delivery cannula and along at least a portion of the barrier member into the working region to disrupt tissue on only one side of the barrier member, within the working region.

Abstract
An apparatus for disrupting tissue in the intervertebral disc space that includes a barrier member having a first configuration for insertion into the disc space and a second configuration when deployed within the disc space. The second configuration of the barrier member is adapted to at least partially define a perimeter of a working region within the disc space. The apparatus also includes a tissue disruption tool configured for insertion into the working region.

2. An apparatus for disrupting tissue in an intervertebral disc space, comprising:
-
a barrier member having a first configuration for insertion into the disc space and a second configuration when deployed within the disc space, wherein the second configuration of the barrier member is adapted to at least partially define a perimeter of a working region within the disc space; a tissue disruption tool configured for insertion along at least a portion of the barrier member into the working region, up to a distalmost tip of the barrier member, without extending beyond the distalmost tip of the barrier member, wherein the tissue disruption tool is configured to disrupt tissue on only one side of the barrier member, within the working region; and a delivery cannula including first and second lumens, wherein at least a portion of the barrier member is positioned within one of the first and second lumens prior to deployment of the barrier member into the disc space, and at least a portion of the tissue disruption tool is positioned within the other one of the first and second lumens prior to deployment of the tissue disruption tool into the disc space.
