A PEEK spacer for use in the spine is disclosed. The PEEK spacer may be configured to fit through Kambin's Triangle and expand upon insertion.
Claims20
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, and
- wherein the spacer length dimension is smaller than the longitudinal length dimension of each of the first and second expandable members.

A system for performing facet sparing spine surgery comprising:
- a spacer, including a spacer body sized to be placed through Kambin's triangle;
- 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 at a respective first and second pivot axis, each of the first and second expandable members defining a longitudinal length dimension between the pivot end and 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;
- and
- a tool configured to move the spacer from a first closed position to a second open position,
- wherein the spacer length dimension is smaller than the longitudinal length dimension of each of the first and second expandable members.
2 more elements
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.
