Abstract
Various embodiments comprise an expansible intervertebral implant intended to be implanted in a space between two adjacent vertebrae to at least partly supplant an intervertebral disc, said implant being able to expand along three substantially mutually orthogonal axes so as to comply with the lordosis of the patient while still having increased stability and reliability.

1-13. (canceled)
An expandable interbody implant comprising:
- a body elongated along a first axis extending between a proximal end and a distal end of the body;
- a first pair of opposing arms pivotally mounted to the distal end of the body, the first pair of opposing arms pivotable from a folded position to a deployed position, each arm of the first pair of opposing arms including a flexible extension extending from a free end of each arm;
- and
- an actuation means configured to transition the first pair of opposing arms from the folded position to the deployed position to laterally expand the interbody implant.

An expandable interbody implant comprising:
- a body elongated along an X-axis extending between a proximal end and a distal end of the body, the body including a superior portion movably coupled to an inferior portion;
- a plurality of arms including a first arm, a second arm, a third arm and a fourth arm, the first arm pivotably coupled to a lateral distal portion of the superior portion of the body, the second arm pivotably coupled to the superior portion opposite the first arm, the third arm pivotably coupled to a lateral distal portion of the inferior portion of the body, and the fourth arm pivotably coupled to the inferior portion opposite the third arm;
- a plurality of flexible extensions extending from free ends of each arm of the plurality of arms;
- and
- an actuation means configured to transition the plurality of arms from a delivery position folded against lateral sides of the body to a deployed position pivoted laterally outward to expand the interbody implant along a Y-axis.
