1. An intervertebral spacer comprising:
- a spacer body; and
a first expandable member and a second expandable member, each of the first and second expandable members including a pivot end and a free end opposite the pivot end, wherein only the pivot end is pivotably attached to the spacer body at a respective first and second pivot axis, each of the first and second expandable members defining a longitudinal length dimension spanning from the pivot end to the free end, respectively, and a spacer length dimension is defined as spanning from the first pivot axis of the first expandable member to the second pivot axis of the second expandable member,wherein the intervertebral spacer is sized to be placed through Kambin'"'"'s triangle, andwherein the spacer length dimension is smaller than the longitudinal length dimension of each of the first and second expandable members.

14. An intervertebral spacer comprising:
-
a spacer body; and a first expandable member including a pivot end rotatably attached to the spacer body and a free end opposite the pivot end, wherein the pivot end rotates about a pivot point adjacent the pivot end and the free end sweeps through a radial arc as the first expandable member rotates about the pivot point, the at least one expandable member defining a longitudinal length dimension between the pivot end and the free end; and a second member including a first end attached to the spacer body and an unattached opposing second end, wherein the intervertebral spacer is sized to be placed through Kambin'"'"'s triangle, wherein a spacer length dimension is defined as spanning from the pivot point of the first expandable member to a point where the first attached end of the second member is attached to the spacer body, and wherein the spacer length dimension is smaller than the longitudinal length dimension of the first expandable member. - View Dependent Claims (15, 16, 17, 18, 19, 20)
